Made to cut accurate holes in machinable material, more cleanly and efficiently than ever before possible. Revolutionary thick-cup design, twice as thick as ordinary hole saws, provides more
strength and longer-lasting cutting peformance by eliminating pilot-hole elongation that results in excessive vibration and chatter. Smoother operation also eliminates kick-back that causes operator wrist fatigue, prolongs bearing life of the drill motor
and reduces saw-tooth breakage.
Klein thick-cup hole saws are recommended for steel and cast iron pipe, steel plate, aluminum, copper, brass, stainless steel, wood and plastics. Features include welded seams, one-piece blade with
specially-hardened teeth and slanted knock-out slots in sides allowing easy core removal. Saws cut to a depth of 1 1/8 Inch (29 mm) from one side and up to 2 1/4 Inch (57 mm) when sawing from both sides.
