Machine Tap DIN 371C M6×1 HSS‑Co 6H – right‑hand 40° spiral, Form C (TECWERK)

The Machine Tap DIN 371C M6×1 is a precision engineered machine tap for producing metric ISO threads in blind holes, optimised for use in steel components and standard production environments

• HSS‑Co for high wear resistance
• Right‑hand 40° spiral for chip control
• Form C geometry with flank relief
• Designed for blind holes in steels to 900 N/mm²

Consistent thread fit for repeatable assemblies

The DIN 371C geometry, combined with the ISO thread specification and 6H tolerance class, ensures a predictable fit between bolt and nut across production runs. This results in fewer rework cycles and reduced assembly variance. For purchasers seeking traceable standards, the reference to DIN 13 Sheet 1 clarifies that the thread form complies with recognised metric thread dimensions, aiding procurement and inspection processes. The specification supports consistent torque behaviour and reliable mechanical joints in repeat operations.

Powerful cutting performance in high‑strength steels

Manufactured from HSS‑Co, this tap is suited to machining steels with tensile strengths up to approximately 900 N/mm², offering improved wear resistance and thermal stability compared with conventional high‑speed steels. The right‑hand 40° spiral assists chip evacuation out of the hole, which is particularly important for blind‑hole tapping where chip control prevents jamming and thread damage. The flank relief reduces cutting forces and promotes smoother entry into pre‑formed holes, extending tool life and maintaining thread quality under continuous use.

Practical design for workshop integration and uptime

With a shank diameter of 6 mm and Form C configuration, the tap integrates with standard machine holders and powered tapping spindles designed for production use. The spiral and flank geometry minimise downtime by lowering the incidence of broken taps in blind holes and easing chip disposal during automated cycles. Clear technical parameters permit straightforward tool selection for process planners and maintenance teams, supporting efficient tool stocking and predictable changeover times in both small workshops and larger fabrication lines.

FAQ

What materials is this tap suitable for? The TECWERK machine tap (M6×1 HSS‑Co 6H, SKU 2000867266NW) is specified for use in steels up to approximately 900 N/mm² tensile strength and is therefore appropriate for many medium‑to‑high strength steel applications.

Can this tap be used for through holes? This tap is designed specifically for blind holes; while through‑hole tapping is possible with some geometries, the DIN 371C Form C with a 40° spiral is optimised for blind‑hole chip control rather than through‑hole clearing.

How does the 40° spiral benefit machining? The right‑hand 40° spiral on this TECWERK tap helps evacuate chips away from the cutting zone, which reduces the risk of chip packing in blind holes and supports more consistent thread quality.

What does the 6H tolerance mean for assembly? The 6H tolerance class indicates a standard internal thread fit that balances manufacturability and assembly clearance, providing predictable mating with external threads produced to corresponding tolerance classes.

What is the shank size and how does it affect holder choice? The shank diameter is 6 mm; this dimension allows selection of standard tap holders or collets compatible with a 6 mm shank for secure mounting during machine tapping operations.
