for the Hardest Steels
Not all steel is created equal — and some materials are known for destroying standard cutters.
Turbo™ Endurance+ is built to cut through:
- High-strength structural steels
- Hardened and heat-treated steels
- Wear-resistant plate (e.g. Hardox-type materials)
- Stainless steels
- Work-hardened materials
- Thick and heavy-section steel
These are the applications where heat, resistance, and material hardness cause rapid tool wear and failure.
Overcome Common Drilling Challenges
If you’ve experienced any of the following, this range is built for you:
- Burnt-out cutters after minimal use
- Excessive heat build-up during drilling
- Chipped or broken cutting teeth
- Slow, inconsistent cutting performance
- Poor hole quality in hard materials
Turbo™ Endurance+ is engineered to eliminate these problems, giving you a more reliable and productive drilling process.
Engineered for Extreme Conditions
Turbo™ Endurance+ cutters are designed to maintain performance under pressure:
- Advanced cutting geometry for harder materials
- Enhanced wear resistance for extended tool life
- Efficient chip evacuation to reduce clogging and heat
- Stable cutting under load for accuracy and consistency
This allows operators to push harder and cut with confidence in demanding environments.
More Holes. Less Downtime.
In difficult materials, downtime costs money.
Turbo™ Endurance+ helps you:
- Drill more holes per cutter
- Reduce time spent changing tools
- Maintain consistent cutting performance
- Lower your overall cost per hole
Frequently Asked Questions
What is the best annular cutter for hardened steel?
Turbo™ Endurance+ annular cutters are specifically designed for hardened and high-strength steels. They offer improved wear resistance, reduced heat build-up, and longer tool life compared to standard cutters.
Can you drill Hardox or wear plate with annular cutters?
Yes — however, standard cutters wear quickly in abrasive materials like Hardox. Turbo™ Endurance+ cutters are engineered to handle wear-resistant plate more effectively, delivering longer life and more consistent performance.
Why do annular cutters fail in stainless steel?
Stainless steel tends to work-harden during drilling, which increases heat and causes rapid tool wear. Turbo™ Endurance+ cutters are designed to reduce heat build-up and maintain cutting efficiency in these conditions.
How do I improve tool life when drilling hard steel?
Using the correct cutter is key. Turbo™ Endurance+ is specifically designed for difficult materials, helping reduce wear, improve cutting performance, and extend tool life. Proper speeds, feeds, and coolant will further enhance results.
Are these cutters suitable for site work?
Yes — Turbo™ Endurance+ cutters are ideal for on-site applications where materials are often tougher and conditions are less controlled. They provide reliable performance in real-world environments.
