Technical Details • 1-1/4" (32mm) MEGA Tungsten Carbide 2-1/4" deep hole saw • 2 TCT carbide teeth • Cut 3 times as large a hole using cordless hand drills than with a bi-metal hole saw • Cuts wood, sheetrock, fiber cement board, plaster, fiberglass, OSB, chipboard, MDF, and other tough materials • Use any 1/2"-20 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
***Arbor and pilot bit NOT INCLUDED***
IMPORTANT: We do not recommend using a corded heavy duty drill with these hole cutters nor are they needed. With no sidewall friction to overcome even the largest diameter hole cutters can be used with a cordless drill. These new highly efficient hole cutters require a different approach to maximize their life. They should be used with a 18v cordless drill with the screw setting when available. It will not slow down the cutting operation. With a 3-speed range cordless drill the middle setting works the best for all sizes.
