Feature●1.The annular cutters 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.●2.Made of tough high speed steel material, with longer service life and high heat resistance.●3.Applicable materials include wood, various steel materials,steel plate, aluminum, brass, cast iron, Stainless steel of lower BHN.,etc.●4.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.●5.Includes 1 annular cutter with plastic case.Description

Application
- 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.
- The 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.
- 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
Notes
What Causes Dull or Broken Cutters?
- The primary cause of broken or prematurely dull cutters is a feed rate that is too slow. Slow feed rates will reduce the life of your cutter. Using a firm, steady feed pressure throughout the cut will maximize performance and extend tool life.
- Second reason why cutters break is movement of the drill or work piece. The cutter wall can easily be snapped if the drill and material is not held rigid.
