TAP M16 DIN-376C (6H) HSSE 800 machine-tap

Where standard HSS taps lose their edge in alloy steels, this cobalt-enriched HSSE machine tap holds its own. The TAP M16 DIN-376C (6H) HSSE 800 is built for machinists who need clean, accurate M16 threads with a 2.0 mm pitch, run after run. Its precision-ground Form C chamfer and straight flutes keep chips moving, while the bright finish reduces friction in demanding production environments.

Highlights

• Metric ISO thread standard: M16 diameter, 2.0 mm pitch, tolerance class 6H
• HSSE (cobalt alloyed) high-speed steel for superior wear resistance and heat tolerance
• Form C chamfer with 2-3 thread lead for balanced cutting and centering
• Straight flute geometry for efficient chip evacuation in through and blind holes
• Right-hand cutting direction, suitable for machine tapping applications
• Bright surface finish for reduced friction and improved chip flow

In daily use

This tap excels in general purpose steels, alloy steels, and cast iron. The four straight flutes provide ample chip space, while the DIN 376 standard ensures compatibility with common tap holders and collets. The 12 mm shank diameter and 9 mm square drive allow secure clamping in tapping heads or drill chucks, minimizing slippage during high-torque operations.
