Sentinel 67 Series
The Sentinel-67 Series is purpose-built for hard milling, specially developed for high-precision finishing of hardened steels up to 67 HRC with our FLATCOAT® TTN coating. This series delivers reliable performance in one of the most demanding material categories in mold and die manufacturing.
PREMIUM CARBIDE, 100% QUALITY CONTROL CHECK
Every ST Sentinel 67 tool is made from high-performance, ultra-fine grain carbide and undergoes 100% inspection. From geometry to balance, nothing escapes scrutiny. This ensures you get tools that perform with tight tolerances, superior durability, and zero surprises—even under high-speed, high-load conditions.
FLATCOAT® TTN COATING
Designed for ultra-hard materials, our FlatCoat® TTN multilayer coating delivers maximum thermal stability, wear resistance, and smooth chip flow. It outperforms standard TiN coatings thanks to its advanced layer structure, which resists peeling and abrasion—even at high speeds. Less heat, less wear, more performance.
CLEANER MILLING RESULTS, LONGER LIFETIMES #MILLMOREUNITS
With robust geometry, premium carbide, full-quality inspection, and the FlatCoat® TTN coating, the ST Sentinel 67 Series thrives in extreme environments. You'll experience longer tool life, superior surface finishes, and reduced tool changes—keeping your spindle running and your workflow efficient.
