Milwaukee Tool 49-56-9659 Bi-metal Hole Saw 7/8 in

Product Description

The MILWAUKEE TOOL 49-56-9659 is a bi-metal hole saw designed for cutting through metal and other common trade materials. It features a toothed cutting edge and delivers a cutting depth of 1-5/8 inches with a 7/8-inch saw diameter. The arbored design accepts a 3/8-inch shank, making it compatible with standard drill setups. This hole saw is suited for electricians, plumbers, HVAC technicians, and general contractors who need reliable, repeatable cuts in sheet metal, electrical boxes, conduit plates, and similar applications.

This hole saw is used in light-to-medium metal cutting applications found in residential and commercial trade work. Typical install scenarios include drilling knock-outs in electrical enclosures, cutting access holes through metal studs, and creating penetrations in HVAC sheet metal panels. The compact 7/8-inch diameter makes it a go-to size for conduit and small-bore pass-throughs. It ships as a single hole saw unit and is intended as a direct replacement or supplemental addition to a hole saw kit.

Installation Notes

Installation is performed by electricians, plumbers, and HVAC technicians using a standard corded or cordless drill or driver. Ensure the workpiece is secured before cutting to prevent movement and maintain hole accuracy. Use appropriate cutting fluid or lubricant when drilling harder metals to reduce heat buildup and extend blade life. Always wear appropriate PPE including eye protection when operating hole saws.
