3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.
4.Ground flutes provide fast chip removal to maximize accuracy and efficiency along the full working surface of the bit.
5.Short length drill bit offers rigidity to reduce tool deflection and breakage. |
