Product Features:
1.Special groove design:High-speed feed,high precision,suitable for difficult machining
conditions such as lathe machining that is easy to block.
2.Hole wall high finish: Grinded with new fine particle tungsten steel bar smooth and
sharp,not easy to stick to the knife,with high wear resistance and
strength.
3.Chamfering design:The shank chamfering design makes it easier to install the chunk.
4.Unique edge treatment:Using nano technology and advanced grinding technology, the cutting
edge of the drills sharper than before,with less cutting force,
reducing the probability of breaking the drill and improving the
quality of the hole wall.
