Milwaukee Tool 49-22-4084 Utility Hole Saw Kit 11 Pc

Product Description

The MILWAUKEE TOOL 49-22-4084 is an 11-piece bi-metal utility hole saw kit covering a diameter range from 3/4 inch to 2-1/2 inches. The kit includes 8 hole saws with toothed cutting edges, stored in a plastic carrying case for jobsite organization. Bi-metal construction combines a high-speed steel tooth edge with a flexible alloy steel body, delivering durability in wood, plastic, and thin non-ferrous materials. The compact case measures 7.5 inches long by 5.4 inches wide by 3 inches high and weighs 3.2 pounds, making it easy to transport to the work area. Licensed electricians, plumbers, and HVAC technicians commonly reach for this kit when running rough-in through wood framing and light building materials.

This kit is suited for residential and light commercial rough-in work. Electricians use hole saws in this size range to bore through studs and top plates for conduit and cable runs. Plumbers use them for drain, waste, and vent pipe penetrations through wood framing. HVAC technicians use them for low-voltage control wiring, refrigerant line sets, and condensate drain routing. The 3/4-inch to 2-1/2-inch range covers the most common rough-in diameters encountered in these trades. The included plastic storage case keeps saws organized and protects teeth between uses.

Installation Notes

Install hole saws onto a compatible arbor before use and confirm the arbor locking mechanism is fully engaged before applying power. Use appropriate PPE including safety glasses and work gloves when boring. Electricians should verify circuits are de-energized and plumbers should confirm water is shut off before cutting through existing assemblies. Follow applicable NEC, IPC, or IFGC clearance and firestopping requirements when creating penetrations through fire-rated assemblies.
