Technical Details
• 1-3/4" (44mm) MEGA Tungsten Carbide 2-1/4" deep hole saw
• 2 TCT carbide teeth
• Cuts wood, sheetrock, fiber cement board, plaster, fiberglass, OSB, chipboard, MDF, and other tough materials
• Use any 5/8"-18 thread hole saw arbor and any standard 3-3/4" or longer pilot bit
• Do NOT use with 1/2" stud drills such as Milwaukee Hole Hawg which will cause the teeth to rip off
• USE on cordless drill MEDIUM to HIGH SETTING for best results
I have hardware cloth in my ceiling, so a regular hole saw failed very quickly. This thing ripped two holes in my ceiling and didn't even notice. It's a shame I don't have dozens more to do, because this tool looks ready for real work.
