Milwaukee 49-57-8311 Carbide Annular Cutter 1 Inch Sheet Metal

Product Description

The MILWAUKEE 49-57-8311 is a quick-change carbide-tipped annular cutter designed for cutting clean, precise holes in sheet metal and thin structural materials. With a 1-inch bit diameter and a 3/16-inch cutting depth, it handles stainless steel, structural steel studs, brass, aluminum, and other thin sheet materials. The carbide tip maintains cutting performance across these harder materials where standard bi-metal hole saws wear prematurely. This cutter is rated for materials up to 3/16 inch thick and is compatible with hand-held drills, delivering hole quality comparable to a drill press setup when used correctly.

This annular cutter is suited for HVAC, mechanical, and sheet metal trades where repetitive hole cutting in stainless or structural steel is required. Typical applications include cutting holes in steel studs, ductwork flanges, and metal framing components. It is equally effective on non-ferrous sheet materials such as brass and aluminum, making it a versatile addition to a sheet metal installer or mechanical contractor's tool kit. Use with the Milwaukee quick-change arbor 49-57-0035 for fast bit swaps on the job site. Lubrication during drilling is strongly recommended to extend carbide tip life. Milwaukee recommends Hawg Wash cutting fluid, available as part number 49-32-0081, which mixes to produce one gallon of lubricating solution per 16-ounce bottle.

Installation Notes

This cutter is installed and operated by sheet metal workers, mechanical contractors, and HVAC technicians. Always ensure the workpiece is secured before beginning the cut and apply cutting fluid throughout the drilling operation to protect the carbide tip. Disconnect or de-energize any adjacent electrical systems before drilling into metal framing or structural members. Do not operate without the recommended arbor, and inspect the carbide tip for wear or chipping before each use.
