The Tolsen 75119 is a 6mm HSS drill bit for metal and stainless steel applications. M2 steel construction maintains hardness during high-speed rotation. Following DIN338 standards, the bit measures 93mm in total with a 57mm flute. This model updates the 75081 by switching to a Titanium Nitride coating and a 130° split point. These changes reduce bit walking and improve heat resistance during heavy drilling.
Key Features
- 130° Split Point: 130° split point for precise self-centering and reduced walking. Bit stays on target without a center punch.
- M2 High-Speed Steel: M2 construction provides heat resistance up to 600°C for durability. Resists dulling when drilling through hard alloys.
- 3-Flatted Shank: 3-flatted shank design prevents slipping in the drill chuck. Stops the bit spinning under high torque.
- Titanium Nitride Finish: Surface finished with Titanium Nitride for lower friction levels. Reduces heat buildup during industrial metal drilling.
- Heavy-Duty Application: Hardened material handles road dust and debris during metalwork. Maintains cutting edges even in high-heat environments.
Frequently Asked Questions
Is Tolsen 75119 good for stainless steel?
Yes, the M2 grade steel cuts through stainless steel and hard metals. The 130-degree point angle prevents the bit from overheating on tough surfaces.
What is the difference between black and gold drill bits?
Gold bits use Titanium Nitride coating for better lubrication and heat dissipation. Black oxide bits offer basic corrosion resistance but lack the same hardness levels.
