The Tolsen 75124 cuts through industrial metals using an M2 high-speed steel core. With a 130-degree split point, the 8.5mm tip stops walking across smooth surfaces. This jobber length bit adheres to DIN338 standards for consistent hole diameter in metalworking.
Key Features
- 130° Split Point: Self-centering 8.5mm tip geometry prevents bit wandering. It starts holes immediately on stainless steel without center punching.
- M2 HSS Construction: Hardened alloy retains structural integrity at high temperatures. The edge stays sharp despite heavy friction in dense iron.
- Black/Gold Finish: Dual-layered coating manages heat dissipation and surface lubricity. It stops metal chips from welding to the 75mm flute.
- DIN338 Standard: 75mm flute length within a 117mm total body. It maintains alignment during deep drilling in thick metal blocks.
Frequently Asked Questions
Is Tolsen 75124 suitable for stainless steel?
The M2 high-speed steel grade cuts through stainless alloys. High heat resistance prevents the cutting edge from softening under load.
What is the difference between black and gold drill bits?
The black oxide retains lubricant while the gold finish lowers friction levels. This combination stops the bit from seizing in humid work environments.
