I’m astounded constantly by the number of unique designs, shapes, and mechanisms for the best adjustable kettlebells on the market. There are quick-changing kettlebells from REP and Titan Fitness, competition-style kettlebells from Bells of Steel and others, and even compact solutions from the likes of PowerBlock.
Then, there are kettlebell handles—pieces of equipment that can take your weight plates or dumbbells and transform them into free weights suitable for your kettlebell training. Among these options, the Ironmaster Quick-Lock Kettlebell Handle stands out since the handle is only compatible with weights used in the Ironmaster Adjustable Dumbbell Set. Using the same quick-locking screw components, this add-on handle could be a fun, engaging way to make the most of your adjustable strength training setup.
The question remains, though, is this kettlebell handle worth it to the average consumer, or is it better-suited for a specific buyer? I’ll discuss this and more in our Ironmaster Quick-Lock Adjustable Kettlebell review.
Honest Expert Reviews? We Can Handle That
We’ve covered honest and informative fitness equipment reviews at Garage Gym Reviews since 2014. Our team of product testers and writers spans a diverse range of expertise in the fitness world, including certified personal trainers, nutrition coaches, strength and conditioning specialists, and competitive athletes. We know what classifies as high-quality home gym equipment through our combined decades of experience in and out of training centers.
To date, we’ve tested more than 15 adjustable kettlebells along with quite a few traditional kettlebells. For the Ironmaster Quick-Lock Kettlebell Handle, I had GGR Senior Staff Writer Stephen Sheehan, CPT, CNC, test out the product through a variety of kettlebell exercises. He scored the kettlebell handle from 1 to 5 on several factors in accordance with our kettlebell testing methodology. Stephen looked at things such as:
- Durability: Adjustable kettlebells can be constructed of several moving parts, so we want to make sure they last through regular use. A 3 out of 5 means the kettlebell should hold up despite some parts that wobble or shift during training. Top scores go to drop-proof adjustable kettlebells (but you should never drop your weights outright).
- Adjustment Speed: How quickly can weights be adjusted? A removable pin selector gets a 3 out of 5, but higher scores go to quick adjustments that can be executed at the turn of a knob or dial.
- Weight Range: Ranges can vary product to product, but we rate a kettlebell that adjusts up to 35 pounds at a middle-of-the-road 3 out of 5, reserving top marks for ‘bells that reach 60 pounds or heavier.
- Shape: Not all adjustable kettlebells have the look and feel of a fixed kettlebell. Here, we note any odd silhouettes that might limit your range of motion, with kettlebells closely resembling a standard kettlebell earning a 4-out-of-5 score or higher.
A Quick Look at the Ironmaster Quick-Lock Adjustable Kettlebell
Ironmaster is largely known for the brand’s innovative strength training equipment made specifically for home or garage gyms, and this focus is fitting considering their slogan, “Strength For Life.”
What they’re best known for is their Quick-Lock Adjustable Dumbbell System. These high-quality adjustable dumbbell handles are thick and knurled like a barbell, and they use square 2.5-pound weight plates to make 5-pound adjustments from 5 to 75 pounds (or 2.5-pound adjustments for uneven dumbbell training). An add-on kit can be purchased, as well, which can take your dumbbell working totals as high as 165 pounds.
RELATED: Ironmaster Quick-Lock Adjustable Dumbbells Review
The Ironmaster Quick-Lock Adjustable Kettlebell is part of the Quick-Lock ecosystem, allowing you to attach the same weight plates to the kettlebell handle through the use of the quick-lock dials—a spin-lock screw that twists through the center of each weight plate. While secure and stable in its own right, this locking pin design can also be beneficial thanks to its flat-faced nature that can help keep free weights comfortable when rested against your body in racked positions.
The kettlebell’s empty handle weighs either 12.5 or 22.5 pounds, depending on which profile you purchase. We tested out the 22.5-pound version, but they’re both made similarly with a powder-coated cast iron construction.
Before You Buy
- If you have the QLDB set, you can simply use the weights from the dumbbells, but people new to Ironmaster will need to purchase a separate weight kit for the QLKB (Quick-Lock Kettlebell).
- Ironmaster offers free shipping to the lower 48 states. People in Alaska, Hawaii, and Canada will see shipping options and costs during the checkout process, but other international shoppers will need to contact Ironmaster directly for a quote.
- If you’re also in the market for adjustable dumbbells, purchasing a custom adjustable dumbbell package (which can include the QLKB, dumbbell stand, and extra weights) can save you a good bit on your order. An order over $1,100 nets you a 5% discount, while an order over $1,600 gets you a maximum discount of 10% off your order.
Is the Ironmaster Quick-Lock Adjustable Kettlebell Worth It?
Frankly, the Quick-Lock Adjustable Kettlebell Handle is a great product; Ironmaster has a reputation for producing durable goods for the home gym crowd, and this kettlebell handle is no different. Ironmaster believes in the product, too, offering a limited lifetime warranty with the handle.
Still, the amount of value you’ll see in this adjustable kettlebell will likely come from whether or not you’ve already invested in the Ironmaster Quick-Lock system. If you already own the brand’s dumbbells, you’re paying (at most) $99 for the 22.5-pound handle. However, if you don’t have the adjustable weight, you’ll have to get the weight kit—an additional $139. To reach 80 pounds (for the heavier handle), you’ll also need to buy the expansion kit, which is another $115.
Depending on your situation, the kettlebell handle can cost as much as roughly $350, making it a much lower value than other available options. The Bells of Steel Adjustable Competition-Style Kettlebell, for example, can reach as much as 70 pounds and still is $20 less. The Titan Fitness Plate-Loadable Kettlebell Swing, on the other hand, costs $75 and is compatible with standard change plates that you’d use with your Olympic barbell.
Accordingly, we rate the price at 2.5 out of 5. If you have Quick-Lock weight plates already, this is great value, but otherwise, you may have to consider the other available options.
Great for:
- People who like the classic powder-coating of a kettlebell handle
- Those who want an adjustable kettlebell that goes heavy
- Home gym users who already own Ironmaster adjustable dumbbells
Not recommended for:
- Gym enthusiasts looking for a high-value product
- Those wanting a faster adjustment mechanism for HIIT workouts
- Lifters who prefer the classic rounded shape of standard kettlebells

Using the Ironmaster Quick-Lock Adjustable Kettlebell
The Ironmaster Quick-Lock Adjustable Kettlebell was tested out by certified personal trainer (and GGR Senior Staff Writer) Stephen Sheehan. He took the kettlebell handle through multiple kettlebell exercises to get a feel for the free weight’s shape and grip. These movements included a range of kettlebell snatches, swings, goblet squats, and more.
Stephen was most impressed by the actual grip and its ergonomics, rating the handle quality at 5 out of 5. With a grip diameter of 1.375 inches (about 35 millimeters) on the 22.5-pound handle, it’s about the size of your standard fixed kettlebell—ideal for building grip strength as seen in a 2015 study1. With the powder-coated exterior, it gives you a good grip during exercises, too. “It’s wide and grippy enough for both one- and two-hand kettlebell exercises,” adds Stephen.
Unlike the handle, the shape of the bell didn’t impress Stephen nearly as much. “The handle itself resembles a standard kettlebell,” Stephen reiterates. “However, it uses square weight plates, giving it an odd shape. Plus, it’s totally flat on the bottom.” The odd square shape and flat end may make catching a kettlebell snatch or clean awkward or downright uncomfortable. As such, Stephen gives the kettlebell shape a 2.5 out of 5.
Let’s look into other aspects of this adjustable kettlebell handle.
Construction and Durability
When it comes to adjustable dumbbells and kettlebells, the most durable pieces of equipment are those that tend to avoid plastic components, especially when it comes to the inner workings. Ironmaster succeeds in making a durable product with its completely metal build, earning a 4.5 out of 5 for the construction. The powdercoat finish of the handle and weight plates is also high-quality. “It all feels heavy-duty in use,” Stephen mentions.
Stephen rates the overall durability slightly lower, however, at 4 out of 5. “The adjustable design with the weight plates makes me a little wary about dropping it,” he explains. He’s right; while accidents can happen, we usually recommend not dropping adjustable dumbbells or kettlebells outright.
This kettlebell, in particular, has a greater chance of being dropped on its quick-lock screw, since it’s located directly on the bottom of the kettlebell. So, while we consider this a highly durable adjustable kettlebell, I wouldn’t recommend dropping it if you can avoid it.
Weight Range
When using the 22.5-pound kettlebell handle and standard weight kit, you can add weight plates in 2.5-pound increments to reach a maximum weight of 57.5 pounds; the 12.5-pound handle starts and ends 10 pounds lighter. You can also purchase an add-on kit with a longer quick-lock screw and a 22.5-pound weight plate, giving you room to reach a max weight of 80 pounds (70 pounds with the lighter 12.5-pound handle).
The Ironmaster kettlebell handle has the potential to reach substantial weight, especially for an adjustable kettlebell profile. Still, we rate the weight range at 4 out of 5 because the extra weights are all additional purchases.
Adjustment Speed
Honestly, if you’re in the market for a quick-changing adjustable kettlebell, look elsewhere. The name “quick-lock” doesn’t describe the weight-changing process very well, as the kettlebell handle is essentially a loadable dumbbell handle. You’ll have to unscrew the quick-lock dial, add or remove weight plates, and then screw the dial back in to properly secure the kettlebell weights.
It’s not as bad as having to use an Allen wrench for an adjustable competition-style kettlebell, but it’s still a process, nonetheless. Stephen rates the adjustment speed at 2.5 out of 5.
Ironmaster Quick-Lock Adjustable Kettlebell vs REP Fitness Adjustable Kettlebells
If you close your eyes (although we don’t advise it because kettlebells are heavy) when using the REP Fitness Adjustable Kettlebells, you will think that you are using a regular kettlebell. The adjustment mechanism works quickly and efficiently, allowing you to make seamless transitions during your workouts.
To show the many differences between adjustable kettlebell designs, let’s compare the Ironmaster Quick-Lock system to the REP Fitness Adjustable Kettlebell—our current pick for the best adjustable kettlebell. Both are solid options but can cater to different audiences depending on what you’re looking for in your kettlebells.
The REP Fitness Adjustable Kettlebell comes in three different weight ranges:
- 8 to 16 kg (17.6 to 35 lbs)
- 16 to 24 kg (35 to 53 lbs)
- 20 to 40 lbs
Seeing as the maximum weight available is 53 pounds, the Ironmaster kettlebell can be a better choice for someone needing a heavier working total. That said, REP’s adjustable kettlebell is a bit cheaper, with the most you’ll spend being $220 for the heavier kettlebell. Ironmaster’s handle and standard weight kit (up to 57.5 pounds) will cost about $240. Ironmaster has smaller weight adjustments of 2.5 pounds, as well, compared to the 5-pound or 2-kilogram jumps from REP Fitness.
Another major difference is the adjustment speed. The REP kettlebells use a push-and-twist-dial. Basically, stack the outer shell onto your weights, twist the dial to your desired working weight, and the shell locks together to achieve the desired total. It’s a much quicker process than the Ironmaster setup.
That said, each kettlebell has its perks. If you’re looking for a quick adjustment system, REP Fitness certainly has the better option. Meanwhile, the Ironmaster QLKB handle offers the potential to go heavier and will end up costing less if you already have a pair of the brand’s adjustable dumbbells at your disposal. Compare these silhouettes further with the chart below.

Customer Experience
Stephen rates the customer experience at 4.5 out of 5. Even though there are somewhat limited ways to contact the company (I could only find phone and email options), Ironmaster has pretty solid policies for potential buyers.
Amongst these policies, Ironmaster provides a 30-day satisfaction guarantee; the company simply asks to have the equipment in its original packaging and securely fastened to prevent any scratching during the return shipping.
The Quick-Lock Adjustable Kettlebell Handle is also backed by a limited lifetime warranty. As long as you use the equipment as directed in the instruction manual, any issues or defective parts will be replaced not including any natural wear from the finish of the kettlebell.
Ordering and Assembling the Ironmaster Quick-Lock Adjustable Kettlebell
The Ironmaster Quick-Lock Adjustable Kettlebell is available only through the company website, but shipping is included if you reside in the contiguous United States. Although Ironmaster offers financing through Affirm, it appears that they don’t offer it for the $99 kettlebell handle, likely because it’s a smaller purchase than some of their bigger products (like the Ironmaster Super Bench Pro V2).
Assembling the adjustable kettlebell handle is fairly simple, too, as you’re just adding or removing weights. One important thing to note is that the instruction manual specifies to always align the weight plates so that the Ironmaster logo is facing outward. Doing otherwise might cause unnecessary damage to your equipment (and void your warranty).
Customer Reviews
At the time of this writing, Ironmaster has a perfect 5-out-of-5 score from a total of 58 customer reviews. Normally, with that high of a score, I might perceive that companies may delete their bad reviews to inflate their scores, but Ironmaster seems to be a legitimate and established brand, so I doubt that’s the case in this instance.
As the score would imply, reviews were positive, although many of them focused on the value of the kettlebell handle if you already had the Ironmaster dumbbells. The value is certainly there, as long as you’ve bought into the Ironmaster ecosystem already. Many reviews said if you already had the Ironmaster weight plates, this was a “no-brainer.”
Aside from the value, customers also appreciate the solid construction of the kettlebell, particularly the grippy and comfortable handle itself.
Final Verdict of Our Ironmaster Quick-Lock Adjustable Kettlebell Review
The Ironmaster Quick-Lock Adjustable Kettlebell Handle is a well-constructed adjustable kettlebell. While it’s certainly a solid option for a durable adjustable kettlebell that can go heavy, it can get quite pricey if you need to purchase a weight kit along with the kettlebell handle. However, if you already have the dumbbell handles and plates from Ironmaster, then this can be a great addition to your home gym setup.
- Although it’s an entirely metal construction, the Ironmaster Kettlebell Handle shouldn’t be dropped, as you’ll be exposing the quick-lock screw to most of the direct impact.
- Depending on which handle you go with, you have the potential to go up to 70 or 80 pounds with this kettlebell handle—well above the average weight we’ve seen in the category.
- The quick-lock dial locks quickly, but changing weights is still a somewhat tedious process. This isn’t the best pick if you’re looking for quick weight changes during your kettlebell workout.
Ironmaster Quick-Lock Adjustable Kettlebell
With a durable cast iron handle and weight range up to 80 pounds, the Ironmaster Quick-Lock Adjustable Kettlebell can be an excellent addition to your home gym to complement your Ironmaster adjustable dumbbells. While the quick-lock screw does take more time for adjustments than a push-and-twist dial or selector pin, the high-quality design and compatibility with Ironmaster adjustable weight plates make this a viable option for kettlebell enthusiasts everywhere.

Ironmaster Quick-Lock Adjustable Kettlebell: FAQs
Are Ironmaster dumbbells worth the price?
To be honest, the Ironmaster Quick-Lock Adjustable Dumbbells aren’t going to be the best adjustable dumbbells for every garage gym, although we think they’re a solid piece of equipment. If you’re looking for a pair of adjustable dumbbells that can go heavy, these are them; they can reach a weight of 165 pounds with an expansion kit.
That said, making adjustments is slow, so if you need a quick-changing dumbbell, there are faster options on the market.
How heavy is the Ironmaster Quick-Lock Adjustable Kettlebell?
The Ironmaster Quick-Lock Adjustable Kettlebell Handle begins at 12.5 or 22.5 pounds, depending on which weight you purchase. You can add weight kits to get the kettlebell weight up to 70 or 80 pounds, respectively.
Who makes the best adjustable kettlebells?
The ideal adjustable kettlebell will vary from person to person due to their fitness levels, training goals, and budget. However, we think the REP Fitness Adjustable Kettlebells will suit most people looking for an adjustable kettlebell. These kettlebells have a sizable weight range, a shape similar to a traditional kettlebell, and they’re competitively priced.
What is the weight limit for Ironmaster Quick-Lock Adjustable Dumbbells?
The Ironmaster Quick-Lock Adjustable Dumbbells reach a maximum weight of 75 pounds by themselves, but add-on kits can boost the maximum weight to 165 pounds.
