Hole processing field such as engineering,rail transit, bridges, ships, machinery manufacturing, aerospace. Re-sharpening：can be easily re-sharpened on a grinding machine and can be re-used for drilling. Processing Aplication Suitable for working with both ferrous and non-ferrous metals,cast iron, stainless steel, aluminum,copper,and plastic,wood, in either plate. Time saving：The annular cutters have fewer teeth and less wear, therefore with an annular cutter holes can be made at higher or faster cutting speed and a faster feed rate of the drilling machine. Easy Using：Due to the unique geometry of the annular cutters, making holes at awkward angles is also very easy. Make overlapping holes, slotting holes and edge cuts; Cuts holes in steel accurately, quickly & safely. Large holes can be drilled up to ten times faster...

Re-grinding can be done until the desired cutting length is available on the annular cutter. HSS annular cutters required Cutting oil, not coolant. Mild & Structural Steel. 2 Inch Annular Cutter Cement Drop In Anchors OSCARBIDE 1-3/16"x2 Annular Cutter,3/4 Inch Weldon Shank,1-3/16 Inch Cutting Diameter,2 Inch Depth Of Cut,2 Flat Mag Drill Bit With Pilot Pin For Magnetic Drill Press,1 Piece Mag Drill Magnetic Drill Press Bits Product description No pre-step drilling is required; holes are cut in as little as 15 seconds Brand Name: OSCARBIDE Material: High Speed Steel (HSS) Weldon Shank: 3/4 inch Cutting Depth: 2 inch Cutting Diameter: 1-11/16 inch Number of Flats: 2 Pilot Pin Size: 1/4 inch x 4 inch(6., 34x102mm) A correct lubrication and coolant delivery more life for annular cutters. OSCARBIDE Annular bits will drill large holes up to ten times faster than regular drill bits,and the mag drill bits are thin-walled and have dual alternating teeth for efficient and aggressive cutting that is easier than traditional hole saws and twist drill bits,It can drill a much larger hole and requires less force and time. Annular cutters help make holes in pipe and tubes without dimpling and deburring. Insert the ejector pin inside the annular cutter,never use an annular cutter without an ejector pin. these cutters can be easily used with light duty drilling machines or portable magnetic base drilling machines. More finishing：The hole made using an annular cutter is more finished, precise and accurate. Best used with a drill press or magnetic drilling machine, both for their stability against high torque forces created by such a drill bit and lower RPMs compared to other types of drills. These HSS Slugger Bit ability to re-sharpen and burr-free holes and smooth holes, resulting in less scrap and wastage of material,has higher accuracy and multiple cutting edges for ply-cutting and lower friction to reach better performance of endurance and removal of chips. Features Annular Cutters cut only the periphery of the hole,ejecting the remaining center as a slug.
