Our Internal Coolant Tapping Heads with Axial Compensation represent the pinnacle of quality and technology in CNC threading. Designed to deliver precision, durability, and superior performance, they are entirely manufactured in Italy using premium materials and are Accredia-certified, ensuring a threading depth tolerance of just ±0.1 mm.

Ideal for machining centers and programmable machines, these tapping heads feature MAS 403 BT Form B toolholders with interchangeable bushings for optimal adaptability to various machining needs. The axial compensation (also available in Code S version for pull-out compensation) ensures flawless threading by eliminating quality issues in thread profiles.

Thanks to high-pressure internal coolant systems, these tapping heads optimize lubrication and cooling, extending tool life and enhancing performance. Coolant flows through side holes, ensuring uniform fluid distribution during operation.

Their versatility makes them suitable for all CNC, mechanical, automatic, and programmable machine tools, effectively solving traditional tap and die threading challenges.

By choosing our tapping heads, you select a product that combines certified precision, robustness, and high performance, while reducing machining time and operational costs.
