Optimized and patented, the BLUE-TEC coating offers unique durability and performance on all types of steel.
- Excellent grip thanks to fine toothing, perfectly controllable on cylinders.
- Suitable for all types of steel, such as extra hardened steel up to 70 HRC and stainless steel (RVS). Heat resistant thanks to the Blue-Tec coating.
- Also suitable for heat-resistant materials, such as nickel- and cobalt-based alloys.
- Unique durability and performance on all types of steel, ideal for milling cylinders with hardened steel.
- Hardness: HP-4
- Suitable for cast iron.
The difference between the normal cutter and the Extreme BLUE-TEC cutter:
This Extreme cutter is especially suited for extra-secured cylinders. Where the normal cutter stops, this one goes further.
Note: Cheaper imitations are also on the market.
Many milling bits are sold as cylinder cutters, but in reality, they are not specifically designed for that purpose.
ETCB's milling bits are specifically developed for opening profile cylinders and tested for hardness, durability and precision.
Our milling bits are among the best on the market and suitable for intensive professional use.
