Electricians, plumbers, and HVAC technicians often need clean, accurate holes in wood, plastic, plasterboard, and thin metal. The Wolfcraft 2165000 hole saw set provides five bi-metal hole saws in common diameters—35, 40, 50, 68, and 83 mm—together with an arbor and centering drill bit, all packed in a robust plastic case. The variable pitch tooth geometry and HSS bi-metal construction deliver efficient cutting in a range of materials, while the hexagonal shank ensures a secure grip in drills and cordless screwdrivers.

Why choose it

The bi-metal construction combines a hardened tooth edge with a flexible body, reducing breakage risk and extending service life. Variable pitch teeth minimize vibration and produce cleaner holes. The included arbor and centering drill bit make setup quick, and the case keeps everything organized.

Ideal use cases

• Cutting holes for electrical outlets and cable pass-throughs in drywall and wood
• Installing downlights and recessed fixtures in plasterboard
• Creating openings for pipes and ducts in wood and thin metal
• General construction and renovation tasks

Good to know

For best results, use a drill with sufficient power and set the appropriate speed for the material. The hexagonal shank prevents slipping in the chuck. The set is suitable for steel up to 2 mm thickness; for thicker metal, use appropriate cutting fluid and lower speeds.
