Straight Shank Type
Morse Taper Shank Type

  • Right handed spiral moves cutting chips forward, and allows hi-speed reaming.  
  • 0/+0.005 blade tolerance as our standard, suitable for high precision holes. 
Cutting Conditions
   1: Refer to the table below before determining the cutting speed r.p.m..
   2: Keep the removal amount to 0.1 dia. - 0.2mm dia. or less for difficult-to-cut materials and 0.2 dia. - 0.4mm dia. for alloy steels non-ferrous metals.
   3: When the best surface roughness is required, use a cutting speed of 0.1mm/rev or less . Normally use 0.1- 0.2mm/rev.
