The Tolsen 75127 Black and Gold HSS Drill Bit bores through metal and wood surfaces. Industrial-grade M2 steel keeps the cutting edge sharp during high-friction tasks. This 10mm bit measures 133mm in total length and adheres to DIN338 industrial standards.
Key Features
- 130° Split Point: Tip geometry stops bit walking on metal surfaces. Starts holes immediately without a pilot hole.
- Black and Gold Finish: Dual-layer coating manages heat and surface lubrication. Prevents bit seizure during heavy drilling.
- Industrial Grade M2 Steel: High-speed steel alloy maintains structural integrity under heat. Resists dulling when used on stainless steel.
- DIN338 Standard: 133mm total length with an 87mm flute length. Matches global specifications for jobber length drill bits.
- Straight Shank: 10mm diameter fits standard keyed or keyless chucks. Stays secure in high-torque industrial drill machines.
Frequently Asked Questions
Is Tolsen Black and Gold drill bit good for metal?
The M2 steel grade and 130° split point penetrate various metals including stainless steel. The coating resists corrosion from high humidity and reduces heat during friction.
What is the difference between HSS and Black and Gold drill bits?
Black and Gold bits use standard HSS but add a specific surface treatment for lubrication. This finish extends tool life and prevents bits from sticking in hard materials.
