Features of product
New Thinning shape
Because of low thrust, achieved excellent biting
property. From biting till hole ends therefore,
possible to get accurate hole size and position.
New margin shape
New margin shape has rigidity and burnishing
action, which reduce
frictional resistance and cutting force resistance.
Smoothing process for flute
Favorable chip shape from low-speed machining
to high-speed machining.
Good chip evacuation machining is realized even drilling depth is 5D and 8D.
