OSCO Industries has operated foundries in South-Central Ohio for nearly 150 years. Serving a wide variety of industrial markets from air conditioning and refrigeration to automotive, power-transmission equipment, and pumps & valves, the team at OSCO were well equipped, ready and willing to make an American kettlebell of the highest standard, using Class 30 Grey Iron to produce our 9LB through 44LB increments. This is the same highly durable cast iron often found in industrial strength frying pans, manhole covers, diesel engine blocks, gearboxes, and machine tool parts.

The town of Cadillac, Michigan has a long and storied manufacturing history, and Cadillac Casting, Inc., has been a big part of it, designing and producing a wide variety of complex and safety-critical components for the automotive industry and other industrial clients since the 1920s. This reputable, privately owned foundry employs 400 highly skilled workers, who seamlessly took on the job of producing the 53LB through 88LB KBs for our powder coat line, as well as our complete E-Coat line. Cadillac uses Ductile Iron, aka nodular cast iron, which contains strong graphite nodules that give it a superior tensile strength and corrosion resistance well suited to automotive components, wheels, gearboxes, machine frames, and, of course, kettlebells.

After casting, each KB is CNC-machined to precisely cut and smooth over the flat bottom and ensure a weight tolerance of +3% / -0% (based on the KG measurement). This machining is handled by Cadillac Casting (in Michigan) and MAKO Finished Products (in Ohio).

Next, the kettlebells are sent for powder coating, with the work handled by two more Midwest leaders: Greenfield Products (Greenfield, Ohio) and CRM, Inc. (Traverse City, MI). These companies have nearly 100 years combined experience, specializing in advanced finishing work for the appliance, automotive, and marine equipment industries. Their advanced powder coating systems enable the proper conditioning of materials for achieving Class A specifications (with maximum inspection time and minimum allowable defects). This textured powder coat finish doesn’t just look good; it delivers an enhanced grip, consistent feel, and scratch/chip resistance beyond that of most traditional kettlebells on the market. With all KB sizes, the finish has a matte black, low gloss appearance with Rogue branding + “Made in the USA” on one side and debossed weight indications in both KG & LB on the other.

Whether you’re purchasing a single set of KBs for your garage gym or outfitting a large facility, this first series of Rogue Powder Coat Kettlebells is available in a wide range of weight increments to suit most goals—from lightweight beginner bells (starting at 9LB / 6KG) up to 53 LBS / 24 KG. The handle diameters, noted below, range from 1.2” to 1.5”. Please Note: The actual weight of each kettlebell is designed to match the KG weight. So for example, the 35LB Rogue Kettlebell is actually spec'd to weigh exactly 16KG with a +3% /- 0% tolerance.
 Rogue E-Coat Kettlebell Handle Diameters:
9LB - 18LB: 1.2"
26LB: 1.4"
35LB - 88LB: 1.5"

The 40LB Rogue Kettlebell meets all requirements for use with the United States Army’s Combat Fitness Test, a 6-event readiness assessment that replaced the previous 3-event Army Physical Fitness Test in 2020. The grueling new ACFT is neutral across all genders and age groups, and includes a strength deadlift, standing power throw, hand-release push-ups, sprint/drag/carry, leg tuck,and a 2-mile run.
