The Tolsen 75114 Black and Gold HSS Drill Bit uses industrial grade M2 steel for boring through stainless steel. Under high pressure, the 130° split point prevents the tip from wandering across metal surfaces. With a total length of 75mm, these bits fit standard chucks for heavy workshop drilling tasks.
Key Features
- 130° Split Point: Precision self-centering geometry for immediate metal penetration. Stops bits walking on smooth surfaces.
- Industrial M2 Steel: High-speed steel construction for drilling through hardened alloys. Penetrates dense materials without edge loss.
- Titanium Nitride Coating: Black and gold finish for heat resistance and friction reduction. Resists thermal damage during high-speed rotation.
- DIN338 Standard: Compliant 43mm flute length for efficient metal chip extraction. Prevents binding during deep-hole drilling operations.
Frequently Asked Questions
Is Tolsen drill bit good for stainless steel?
The M2 grade high-speed steel penetrates stainless steel and hardened alloys. Its 130° point angle maintains focus on hard surfaces.
What is the benefit of the black and gold finish?
This coating reduces friction and heat buildup during heavy metalworking. It extends bit life in humid BD workshop conditions.
