Using industrial M2 steel, the Tolsen 75115 Black and Gold HSS Twist Drill Bit bores through stainless and alloyed metals. Under high-speed rotation, a 130-degree split point prevents this 4.5mm bit from walking. For deep drilling accuracy, this 80mm jobber length tool follows the DIN338 standard.
Key Features
- 130° Split Point: Self-centering geometry reduces bit walking during metal penetration. Holes stay aligned without center punching.
- Black and Gold Finish: Titanium Nitride coating resists high heat during heavy friction. Bits don't soften under load.
- Industrial M2 HSS: High-speed steel construction maintains sharp cutting edge hardness. Edges survive high-speed drilling.
- DIN338 Standard: Fully ground straight shank with 47mm flute length. Road dust won't jam the shaft.
Frequently Asked Questions
What is the use of 130 degree split point drill bit?
The 130-degree split point enables self-centering on hard metal surfaces. This geometry stops the bit from walking before it bites.
Is Tolsen black and gold drill bit good for metal?
This industrial-grade M2 steel bit cuts through stainless and alloyed steels. The titanium nitride coating prevents thermal damage during rotation.
