H&V Expert milling cutters for hard machining were specifically designed and developed to meet the requirements of hardened steels. Selected ultra-fine grain substrates, proven geometries, coordinated edge preparation, and the long-established blue coating form the perfect synergy for reliable machining of hardened steels up to 70 HRC.

• The often imitated but never achieved original blue coating for hard machining.

• Cutting edge preparation tried and tested for decades and optimized to perfection.

• Carbide specially developed for hardened steels.

• Extremely soft cut at up to 70 HRC.

• Radius and face geometries optimized for breakout resistance.

• Sophisticated geometry for reliable chip removal and consistently high process reliability.

• Controlled and even wear
