Jestuous Annular Cutter 3/4 Inch Weldon Shank 1-3/16 Cutting Diameter 2 Cutting Depth Slugger Bits HSS Kit for Magnetic Drill Press

Specifications Cutting Diameter: 1-3/16" Cutting Depth:2" Shank Diameter: 3/4" Shank Style:Weldon Flat Number of Flats: 2 Material:High Speed Steel（HSS） Finish/Coating: Bright Treatment:all-ground Accessory:with 1 pilot pin(6.34*103mm） Packing:plastic box Fits:Hole processing field such as engineering, rail transit, bridges, ships,machinery manufacturing, aerospace. Mild & Structural Steel; Aluminum;Stainless Steel (lower BHN) Application 1. Insert the ejector pin inside the annular cutter.Fill the coolant tank with oil lubrication,never use the machine without lubricant. 2.Requirement to cutting rotate speed of annular cutter are also different for different diameters,and reasonable cutting rotate speed will prolong service life of annular cutter directly,So we recommend:1.The cutting speed:VC=20-25m/min 2.The reasonable rotate feed amount shall be fn=0.08-0.13mm/r 3.The reasonable feed rate shall be vf=36-60mm/min 3.Annular Cutter offers superior holemaking capabilities. It cut faster, last longer, produces a better hole finish, a true round hole with very tight tolerances, can be re-sharpened and drills holes with less power and torque. 4.The cutter is used for drilling through steel. They produce accurate burr-free holes to close tolerances without pre-drilling or step drilling. They can drill a much larger hole and requires less force and time than a standard twist drill bit. Warm Tip Protect your eyes and belongings away from the drilling cutter. About this item Annular cutter are compatible with almost all major brands of magnetic drills, can also be used with machine tools such as mills and large drill presses with tool holders. Made of tough high speed steel material, with longer service life and high heat resistance. Applicable materials include wood, various steel materials,steel plate, aluminum, brass, cast iron, Stainless steel of lower BHN.,etc. The biggest advantage of HSS annular slugger drill cutter bits is its 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. Includes 1 annular cutter and 1 pilot pin(6.34*103mm) with plastic case. See more product details
