The Tolsen 75121 Black & Gold HSS 7mm Drill Bit penetrates industrial-grade metal and stainless steel via M2 high-speed steel construction. A 130-degree split point enables self-centering to stop bit walking on hard surfaces. This model upgrades the previous 118-degree point and replaces the polished finish with heat-resistant black and gold oxide.
Key Features
- 130° Split Point: 130-degree self-centering tip for immediate metal penetration. Stops the bit from skating across smooth surfaces.
- Black & Gold Oxide: Dual-tone finish for lubrication and heat management. Reduces friction to prevent bit breakage in drills.
- M2 Steel Grade: Industrial-grade high-speed steel construction for metalworking. Maintains a sharp edge while drilling hardened alloys.
- Straight Shank: DIN338 standard 109mm length with 69mm flute. Fits into standard 3-jaw chucks in local workshops.
