General Features

Shank Flat and narrow single margin DIN 6535 HAK Reduced frictional resistance and heat development

Large cooling channels Large chip pocket Improved coolant distribution Improved chip evacuation

Sumi-Power Coating Increased wear resistance and long tool life

Sharp cutting edge Stock Size Optimised for stainless steel Ø3,0 ~ Ø12,0 and reduction in cutting forces Increment 0,1mm Ø12,1 ~ Ø16,0 Standard diameter

Advantages

High process reliability in stainless steel and low carbon steel Can be used on low-performance machines! (àavoids overload!) High surface quality in the bore Sharp cutting edge High adhesion resistance by Sumi-Power Coating
