FANAR TAP M10 DIN-376C R40 EL (6H) HSSE 800 Machine Tap for Through Holes

This FANAR machine tap stands out with its extra-long R40 design and cobalt-alloyed HSSE steel, delivering dependable thread cutting in deep or hard-to-reach through holes. The DIN 376 C form with a 2-3 thread lead and 6H tolerance ensures precise metric M10 coarse threads in a single pass.

Highlights

• M10 x 1.5 mm metric coarse thread, DIN 376 standard
• C chamfer form (2-3 threads lead) for through-hole tapping
• HSSE high-speed steel with cobalt for enhanced wear resistance
• Straight flutes for efficient chip evacuation
• Uncoated bright finish, suitable for steel, cast iron, non-ferrous metals, and stainless steel

In daily use

The extra-long R40 shank provides the reach needed for recessed or deep workpieces, while the robust HSSE construction maintains sharpness over extended runs. The 6H tolerance class produces threads that accept standard metric fasteners with a precise fit, reducing the risk of cross-threading or assembly issues.
