Kierretappi M14 DIN-376C R40 (6H) HSSE 800 konekierretappi läpirei'ille

This M14 machine tap in HSSE cobalt high-speed steel delivers reliable thread cutting in through holes. Its spiral point geometry pushes chips forward, preventing clogging and ensuring smooth, precise M14 x 2.0 mm threads to tolerance class 6H. Conforming to DIN 376 with a C chamfer (2-3 threads), it is engineered for efficient, high-quality threading in general purpose steels, alloy steels, stainless steels, and cast iron.

Advantages

The R40 geometry and cobalt-alloyed HSSE material provide high wear resistance and heat tolerance, extending tool life even in demanding materials. The spiral point flute design eliminates chip evacuation problems in through holes, allowing faster cutting speeds and reducing the risk of tap breakage. The uncoated surface offers a cost-effective solution without compromising performance in standard applications. The square drive shank ensures secure clamping and positive torque transmission in machine tapping operations.

Suitable for

• Through-hole threading in steel, alloy steel, stainless steel, and cast iron
• Machine tapping on CNC machining centers, lathes, and drilling machines
• Production environments requiring consistent thread quality and tool longevity
• Thread repair and maintenance tasks where a precise 6H fit is required
