Annular cutters made with super tough M2AL high speed steel (HSS) for durability, wear resistance, high efficiency and superior service life 11 HSS core drill bit cutting tool assortment set with Outside Diameter in inches: 7/16",1/2",9/16",11/16",5/8",3/4",13/16",7/8",15/16",1",1-1/16",1 inch cutting depth for each drill cutter CNC-machined high precision annular drill bit set 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 magnetic drills including Alfra, BDS, Dewalt, Euroboor, Hougen, Ruko. Caution: if you want to use this annular cutter on a drill press, you need an extra annular cutter arbor for the drill bit cutter. Arbor is not included in this pack Sturdy good-looking case holding an assortment of 11 annular bits, 2 pilot pins and a bonus hex wrench Overview Item: HSS Standard Weldon Annular Cutter for Power Magnetic Drill Presses Includes: 11 Annular Cutters, 2 Pilot Pins, 1 Hex Wrench, 1 Carrying Case Cutting Diameter: 7/16”, 1/2”, 9/16”, 5/8”, 11/16”, 3/4”, 13/16”, 7/8”, 15/16”, 1”, 1-1/16” Cutting Depth: 1'' Shank Diameter: 3/4" Shank Style: Weldon Flat Accessories: 2 pilot pins (4.74mmx77mm and 6.34mmx77mm) Material: HSS (High Speed Steel) Finish/Coating: Bright Advantages Time savings: These annular cutters have fewer teeth and less wear; holes can be made at a higher cutting speed and a faster feed rate of the drilling machine. Energy savings：these angular cutter drills do not have to drill/cut through the complete work piece, they require less thrust and thus less energy to drill through material. Re-sharpening: the angular cutter drill can be easily re-sharpened on a grinding machine and can be re-used for drilling. Easy to use: unique geometry design of the HSS annular cutter set, making holes at awkward angles is also very easy.
