Tolsen 75122 bores through stainless steel and alloys using industrial-grade HSS M2. A 130° split point prevents bit wandering on smooth metal faces. This Tolsen industrial drill bit 7.5mm follows the DIN338 standard for consistent sizing.
Key Features
- 130° Split Point: 130° self-centering tip geometry for precise hole starts. With this tip, the bit won't walk across flat workpieces.
- HSS M2 Construction: Industrial grade M2 high-speed steel with high carbon. Under high-speed friction, the metal maintains its structural hardness.
- Dual-Tone Finish: Titanium Nitride coating on a black oxide flute surface. Despite humidity, the coating resists surface oxidation.
- Standardized Dimensions: 69mm flute length with a 109mm total reach. This length clears debris efficiently during deep drilling tasks.
Frequently Asked Questions
Is Tolsen Black and Gold drill bit good for stainless steel?
Industrial M2 steel provides the hardness required for stainless steel penetration. The 130° point angle bites into hard surfaces without slipping.
What is the difference between black and gold HSS bits?
The gold titanium coating reduces heat while the black flute moves chips. This pairing prevents the bit from overheating and snapping.
