Five grooves at the chamfer allow for faster wood removal. A set of 6 6.35mm 90-degree hexagonal tapered drill bits—made of standard high-speed steel. High-frequency quenching heat treatment gives these high-speed steel tapered drill bits high toughness and hardness. The titanium-coated chamfered edges are rust-proof and have a long service life. A set of 3 stepped tapered drill bits: Forged from titanium-coated high-speed steel, the hexagonal drill shank has a grooved design to help the drill hold the drill bit more securely. Suitable for drilling thinner materials such as stainless steel, carbon steel, aluminum plates, and iron plates.
