New Family of Optimized Straight Flute Cut Taps for Steel Balances Chip Control and Thread Quality
Sandvik Coromant has introduced CoroTap® 100 with -PM geometry, a new family of optimized straight flute cut taps for ISO P materials.
Engineered with a high-performance chip-breaking design that drastically reduces production interruptions and eliminates the need for manual chip removal, the CoroTap 100 family enables a safer production environment and a more stable machining process with continuous, reliable output and minimal manual intervention.

“By integrating precise chip management with high-quality threading, we’re helping manufacturers maintain steady production with minimal operator input,” said Cory Carpenter, global product and digital application specialist at Sandvik Coromant. “The chip breaker chamfer may seem like a subtle feature, but its effect is substantial. Applying it to just two flutes allows for efficient chip separation while preserving the accuracy and finish of the thread.”
Effective chip evacuation is critical, especially in blind holes. CoroTap 100 with -PM geometry is optimized for internal coolant delivery, ensuring clean chip removal and a high-quality thread finish. For through holes, external coolant via collets or nozzles is recommended for optimal performance.
“Coolant isn’t just a support function — it’s crucial in precision threading,” said Carpenter. “With the right flow, pressure and concentration, we can prevent chip recutting and maintain a clean, efficient process.”
The CoroTap 100 tap range is available in a comprehensive selection of geometries tailored for ISO P, K, N and H materials. The assortment includes straight flute taps, spiral point taps, spiral flute taps and forming taps, offering manufacturers the right solution for every threading challenge.
