Mastertap M10 DIN 371B (6HX) HSSE-PM Spiral Point Machine Tap for Through Holes

For high-volume through-hole threading in demanding materials, the Mastertap M10 DIN 371B (6HX) HSSE-PM Spiral Point Machine Tap stands apart through its powder-metallurgy HSSE-PM substrate and precision-ground spiral point geometry. Unlike conventional HSS taps, this tool combines cobalt-enriched powder metal with a forward chip evacuation design, pushing chips ahead of the tap to prevent flute clogging and enable uninterrupted machining cycles. The reinforced shank with square drive ensures secure tool holding and reliable torque transmission in CNC machining centers, transfer lines, and automated tapping operations.

Highlights

• Nominal diameter M10 with 1.5 mm metric coarse pitch, conforming to DIN 371B for reinforced shank machine taps.
• Thread tolerance 6HX, optimized for high-quality internal threads in through holes.
• Spiral point (SP) flute design with Form B lead-in chamfer (4-5 threads) for efficient chip evacuation forward.
• Manufactured from HSSE-PM powder metallurgy high-speed steel with cobalt for superior wear resistance and toughness.
• Bright finish and ground thread for precise thread form and extended tool life.
• Recommended for unalloyed and alloyed steels, stainless steels, cast iron, and non-ferrous metals.
• Compatible with oil, emulsion, and air/dry coolant strategies.

In daily use

In production environments, this tap excels at threading through holes in steel and stainless steel components where chip disposal is critical. The spiral point pushes chips forward, eliminating the risk of chip packing in the flutes and allowing continuous operation without frequent tool retraction. The reinforced shank and square drive provide a rigid connection to the machine spindle, reducing vibration and ensuring consistent thread quality even at high cutting speeds. Whether used in dedicated tapping machines or flexible CNC cells, the Mastertap M10 delivers reliable performance and long tool life, reducing downtime and cost per threaded hole.
