[DETAIL] Description 1. [High Quality Alloy Material] Made of high quality alloy, the oxy-nitriding process of the bit improves the hardness of the drill. Long service life and easier to keep sharp than normal steel drill bits. 2. [Precise Drilling] The drill bit has a neat, smooth opening, no broken edge and no chattering. Low resistance to cutting, stable drilling, and higher opening speed. 3. [Durable] Full grinding and anti-rust treatment, clean and sharp, no burr. The drill bit is more wear-resistant and durable. The shank of the drill bit is hexagonal, which makes the drill clamping more firmly and the drill does not slip.
