Strojový závitník M10 DIN 371 C 6HX R45 HSS-PM EL-CUT pre priechodné otvory

When tapping M10 coarse threads in through holes on CNC machines, standard taps often struggle with chip evacuation and tool life. The EL-CUT series from NO NAME changes that: a 45° spiral flute geometry pulls chips forward, out of the hole, preventing clogging and reducing torque peaks. Made from powder-metallurgy high-speed steel (HSS-PM), this tap offers a finer carbide distribution than conventional HSS, resulting in higher toughness and wear resistance. The reinforced shank with square drive ensures secure clamping and reliable torque transmission, while the 6HX tolerance class guarantees a precise fit for standard metric threads. Whether you are machining steels, stainless steels, cast iron, or non-ferrous metals, this tap delivers consistent performance in high-volume production.

Highlights

• 45° spiral flute for efficient chip evacuation in through holes
• HSS-PM substrate for extended tool life and higher cutting speeds
• DIN 371 C with reinforced shank and square drive for stable clamping
• 6HX tolerance class for standard metric thread fits
• EL-CUT technology for reduced cutting forces and improved surface finish

In daily use

This machine tap is intended for use on CNC machining centers, tapping machines, or other rigid setups. The C chamfer form (2-3 threads lead) provides easier starting and reduces the risk of cross-threading. The right-hand cutting direction matches standard spindle rotation. For best results, use a suitable tapping fluid and follow recommended cutting parameters for the workpiece material. The tap is suitable for through holes only; for blind holes, consider a different flute geometry.
