About This

Annular cutters made with super tough M2AL high speed steel (HSS) for durability, wear resistance, high efficiency and superior service life
HSS annular drill bit with Outside Diameter 15/16 inch with 2 inch cutting depth
CNC-machined high precision cutter drill bit cutter with 3/4 inch Weldon shank (with 2 flats) for secure clamping and edge finish designed for smooth, reamed, burr-free edges of drilled holes. Use a firm steady pressure throughout the cut for best results
IMPORTANT Drill single layers of materials only. This series of annular cutter is NOT designed for drilling of multiple layers.
Avoid premature failure of cutter by using a low feed rate when engaging the bit with the work piece, especially for the smaller cutters. Increase to recommended rate once bit is about 2-3mm in.
Secure workpiece firmly before drilling. If workpiece is less than 1/2” thick, use a 3/8” steel sheet under it to ensure the magnetic drill will grip it firmly. There should be no movement between the workpiece and bit during drilling.
Compatible with various brands of mag drill including Alfra, BDS, Dewalt, Fein, Euroboor, Hougen, Ruko. Caution: if you want to use this annular cutter on a drill press, you need an extra annular cutter arbor. Arbor is not included in this pack.
