Machine Tap DIN 371C M10×1.5 HSS‑Co5 6H – 35° right‑hand spiral, RUKO

The Machine Tap DIN 371C M10×1.5 HSS‑Co5 6H is a high‑performance threading tool designed for blind holes in steels, cast iron and non‑ferrous metals, conforming to DIN 13 Blatt 1

• HSS‑Co5 for increased heat resistance
• 35° right‑hand spiral for reliable chip evacuation
• ISO2 (6H) tolerance for precision threads
• Form C for blind‑hole threading

Precision threads with durable high‑speed cobalt steel

The Machine Tap DIN 371C M10×1.5 is manufactured from HSS‑Co5, a cobalt‑alloyed high‑speed steel that improves red‑hardness and wear resistance under elevated temperatures. The combination of material and ISO2 (6H) tolerance delivers consistent, accurate threads in line with DIN 13 Blatt 1, reducing rework and maintaining thread quality across production batches. For industrial workshops and subcontractors, this means fewer rejects and predictable assembly fits when producing metric ISO threads.

Efficient chip control and secure cutting geometry

Engineered with a 35° right‑hand spiral and relieved flanks, the threading tool actively promotes chip evacuation when creating blind holes. This geometry prevents chip packing at the tool tip and lowers the risk of thread damage in through‑stopped holes, improving process reliability. The tool’s 10 mm shank diameter and right‑hand cutting direction ensure compatibility with standard tap holders and automatic tapping spindles, enabling smooth integration into existing machining setups and uninterrupted cycle times.

Broad material compatibility and workshop benefits

Specifically designed for blind‑hole applications (Form C), the tap is suitable for unalloyed and alloyed steels up to 1000 N/mm², malleable cast iron and a range of non‑ferrous metals. The balanced design extends tool life under typical shop conditions and supports efficient production in maintenance, toolroom and serial machining environments. Reliability is further supported by adherence to recognised standards, making this threading tool a practical choice for precision applications where consistent thread quality and process uptime are essential.

FAQ

What materials can be tapped with this tool?
The machine tap is suitable for unalloyed and alloyed steels up to 1000 N/mm², malleable cast iron and non‑ferrous metals; this capability is specified for the RUKO Machine Tap DIN 371C M10×1.5 HSS‑Co5 6H (SKU 4000601998NW).

Is the tap suitable for blind holes?
Yes, the tool is Form C (DIN 371C) and specifically designed for blind‑hole threading, with a 35° right‑hand spiral to aid chip evacuation in stopped holes.

What tolerance and thread quality can be expected?
Threads are produced to ISO2 (6H) tolerance in accordance with DIN 13 Blatt 1, providing consistent metric ISO threads and reliable assembly fits.

Which shank size and cutting direction does the tap use?
The tap features a 10 mm shank and is designed for right‑hand cutting, compatible with standard holders and automatic tapping equipment.

How does the spiral and flank design affect performance?
The 35° spiral and relieved flanks promote controlled chip flow and reduced risk of chip jamming in blind holes, extending tool life and lowering scrap rates for high‑volume or precision operations.
