Tolsen 75118 penetrates stainless steel and hard alloys using industrial-grade HSS M2 steel. Under pressure, the 130° split point holds its position on flat surfaces without skating. This version upgrades the point angle from 118° and adds a heat-resistant Black & Gold finish for better thermal management.
Key Features
- 130° Split Point: 130-degree self-centering geometry prevents bit walking on metal. Starts drilling immediately without center punching.
- Black & Gold Coating: Titanium Nitride finish provides high thermal resistance and durability. Resists corrosion in humid BD workshop environments.
- HSS M2 Material: Industrial grade M2 high speed steel for hard metals. Cuts alloy steel without losing edge sharpness.
- DIN338 Specs: 93mm overall length with 57mm flute length measurements. Fits standard straight shank chucks for deep holes.
Frequently Asked Questions
Is Tolsen 75118 suitable for stainless steel?
Yes, the M2 high-speed steel cuts through hard alloys. High heat resistance prevents the tip from dulling under high-speed friction.
What is the difference between black and gold drill bits?
The dual coating reduces friction while dissipating heat during operation. This stops metal chips from welding to the bit flutes.
