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.
