Milwaukee Tool 49-22-4020 Hole Saw Kit 11-piece Hss

Product Description

The MILWAUKEE TOOL 49-22-4020 is an 11-piece high-speed steel hole saw kit built for multi-purpose cutting in wood, plastic, drywall, and light metal. The kit spans a diameter range of 1-3/8 inches to 6-1/4 inches, covering the most common trade hole sizes needed for HVAC duct penetrations, plumbing rough-in, and electrical box cutouts. Maximum cutting depth is 3 inches. Each saw uses a toothed cutting edge at 3.5 teeth per inch, and the included arbor accepts a 3/8-inch hex shank, making it compatible with standard cordless drills and right-angle drivers commonly used on job sites.

This kit is suited for residential and light commercial trade work where a single portable kit needs to cover multiple disciplines. HVAC installers use it for duct collars and register cutouts. Plumbers use it for pipe penetrations through framing and subfloor. Electricians use it for panel knockouts and fixture rough-in. The clamshell storage case keeps all components organized between jobs. The 1/4-inch pilot drill and 3.5-inch pilot drill length provide accurate starting points without pre-drilling in most framing materials.

Installation Notes

Installation of this kit requires a corded or cordless drill driver with a compatible chuck or hex-shank adapter. Always secure the workpiece before cutting and use appropriate eye and hand protection. When cutting near electrical wiring or plumbing, verify clearances and de-energize circuits or isolate supply lines per applicable NEC or IPC requirements before drilling penetrations. Allow the saw to reach full speed before contacting the material to avoid pilot bit deflection and blade binding.
