Milwaukee 49-22-8210 Carbide Sheet Metal Cutter Set 7 Pc

Product Description

The MILWAUKEE 49-22-8210 is a 7-piece carbide-tipped hole cutter kit engineered for sheet metal and steel plate applications up to 0.5 inches thick. Each cutter uses brazed carbide teeth that stay sharper longer than high-speed steel or bi-metal alternatives, producing clean, burr-free holes without secondary deburring. The set is designed for use with Milwaukee arbors 49-57-0035 or 49-57-0037 and is a go-to solution for electricians, HVAC technicians, and sheet metal fabricators who cut multiple holes per day in demanding materials.

These cutters are well suited for residential and commercial electrical work, HVAC ductwork, and structural steel stud framing. Primary target materials include stainless steel, structural steel plate, and steel electrical boxes. The cutters also perform on cast iron, brass, aluminum, and other thin non-ferrous metals, making the set versatile across trade applications. Milwaukee recommends Hawg Wash cutting fluid (49-32-0081) to extend cutter life during drilling; one 16 oz bottle yields one gallon of lubricating solution.

Installation Notes

Installation is performed by electricians, HVAC technicians, and sheet metal workers. Secure the appropriate Milwaukee arbor before mounting any cutter in the set. Apply cutting fluid throughout drilling to reduce heat buildup and extend carbide tip life. Always follow applicable OSHA and site safety requirements when operating hole cutters on energized or pressurized systems.
