1-1/4" x 1" M2AL High Speed Steel Cyclone Annular Cutter, 3/4" Shank, 2 Flats

Evolution standard geometry is sufficient for most drilling applications. Manufactured specifically to maximize hole accuracy while minimizing cutter vibration and extending annular cutter life. Annular cutters save time and energy when compared to other hole producing methods. While cutting only the periphery of the hole, annular cutters produce a reamed quality, burr-free hole. No step drilling is required & holes are cut quickly and accurately. Tooth hardness is optimized and heat treated to 68HRC to maximize cutter performance. M2AL cutters also include a tapered hardness from the shank, through the cutter body and to the cutter teeth. This makes the cutters more resistant to the torque created while cutting and thus prevent breakage. Includes Pilot Pin
