○ 2D flat hole drilling with 10D ejecting length.(industry's longest) ○ Solid carbide drill for 4D flat hole.
○ From carbon steel to alloy steel. cast iron → Very wide !
○ Enhanced performance on chip breakage and its emission. ○ Intermediate double margin control generation of hole expansion for high accuracy drilling.
Amount of oversize is reduced due to a double margin and the shape of the negative rake blade tip.
Improved resistance to oxidation. heat and wear
