Machine tap DIN 376B M20×2.5 HSS‑Co PM HARDLUBE (TECWERK)

Machine tap DIN 376B M20×2.5 for universal machine tapping in steel, stainless steel and non‑ferrous alloys

• HSS‑Co PM for high wear resistance
• HARDLUBE coating reduces adhesion and wear
• Straight flute, Form B, 2×D length
• ISO metric thread M20×2.5, tolerance 6HX

Engineered performance for consistent thread quality

The TECWERK machine tap specified above is manufactured from HSS‑Co PM, a powder‑metallurgy high‑speed steel with cobalt reinforcement, which increases red hardness and wear resistance. This composition supports longer tool life under demanding cycles and higher cutting temperatures. As a result, the tool offers dependable thread form retention and fewer tool changes during production, improving overall process reliability and machine uptime.

Geometry and coating that extend tool life

The combination of HARDLUBE surface treatment and Form B geometry reduces friction and minimises adhesion in the thread flutes. The straight‑flute design promotes secure chip evacuation for through threads and helps maintain a stable cutting action in mixed materials. Optimised edge rounding and cutting geometry lower the risk of burr formation and reduce rework, which contributes to more predictable cycle times and lower per‑part machining cost.

Precision thread form and reliable tolerances

Designed to produce an ISO metric thread of M20×2.5, the tool meets the DIN 13 Blatt 1 profile and is manufactured to 6HX tolerance, ensuring compatibility with standard mating parts and gauges. The DIN 376 length and a 16 mm shank allow secure clamping in machine tool holders, while the right‑hand cutting direction suits standard spindle setups. These specifications support reproducible thread quality and simplify inspection procedures in serial production.

Versatile application and efficient machining

Rated for universal use, this machine tap machines steel, stainless steel, aluminium and copper alloys as well as cast materials, making it suitable for mixed‑batch environments. The 2×D length and the chamfer designed for through threads facilitate uninterrupted machining of blind and through holes on CNC tapping heads and multi‑spindle equipment.

FAQ

Is this tap suitable for stainless steel?
Yes. The TECWERK machine tap M20×2.5 is specified for use in stainless steel and incorporates HSS‑Co PM and a HARDLUBE coating to improve performance in tougher, work‑hardening materials.

What does the 6HX tolerance mean for assembly?
The 6HX tolerance indicates a standard internal thread tolerance for metric threads; the tap produces threads compatible with standard external threads, facilitating straightforward assembly and interchangeability for M20×2.5 fastenings.

Can this tap be used for through and blind holes?
The tool features a chamfer suited for through threads and a 2×D overall length; it is optimised for through‑hole tapping on machine applications, with reliable chip evacuation via the straight flute.

What are the clamping requirements for this tool?
The shank diameter is 16 mm, which allows rigid clamping in common machine tool holders and reduces runout; ensure the holder supports a 16 mm shank and the machine spindle is set for right‑hand cutting.

How does the HARDLUBE coating affect performance?
HARDLUBE reduces friction and adhesion on the cutting surfaces, lowering torque and heat generation during tapping cycles; this results in longer tool life and more consistent thread quality under higher production loads.
