TECWERK machine tap M4 x 0.7 — HSS‑Co PM, HARDLUBE, DIN 371B

The TECWERK machine tap M4 x 0.7 (DIN 371B) is a universal straight‑flute machine tap designed for efficient production of metric ISO threads in steel, stainless steel, aluminium, copper alloys and cast iron

• HSS‑Co PM for high wear resistance
• HARDLUBE coating reduces friction and build‑up
• Straight flute for secure chip control
• DIN 13 metric thread with tolerance class 6HX

Consistent performance through material and coating choices

The combination of HSS‑Co PM (powder‑metallurgy high‑speed steel with cobalt) and a HARDLUBE surface treatment gives the tap a clearly improved resistance to abrasion and thermal stress. In practice this means more consistent thread quality over longer production runs and fewer tool changes, which raises throughput and reduces unplanned downtime. The metallurgical composition and coating are especially beneficial when machining tougher alloys where heat and wear are limiting factors.

Reliable thread geometry and tolerance for repeatable results

Constructed to DIN 371B dimensions with an ISO metric thread profile and tolerance class 6HX, the tool produces threads that meet common industrial fit requirements. The tool’s optimised cutting geometry and edge rounding reduce the likelihood of burr formation and promote a predictable thread flank finish. For workshops and production environments where interchangeability and conformity are required, this tap supports repeatable assembly and inspection criteria.

Practical shank and flute design for machine use

With a standard DIN 371 overall length, a 4.5 mm shank diameter and a right‑hand cutting direction, the tool mounts cleanly in conventional tapping holders and automatic tapping spindles. The straight flute design assists controlled chip formation and evacuation when producing through threads and pairs well with the included shearing chamfer for faster engagement. These mechanical aspects combine to reduce machining cycle time while maintaining thread integrity.

Versatile application across common workshop materials

Engineered as a universal tool, the tap is suitable for machining through threads in a broad material spectrum: mild and alloyed steel, stainless steel, aluminium and copper alloys, plus cast iron. The tool’s geometry and coating balance cutting forces and surface interaction to lower the risk of workpiece damage and extend tool life. For shops moving between different materials, the tap delivers a pragmatic compromise between specialist tools and general‑purpose performance.

FAQ

What materials is the TECWERK machine tap M4 x 0.7 suitable for?
The TECWERK machine tap M4 x 0.7 is specified for universal use in steel, stainless steel, aluminium and copper alloys as well as cast iron, thanks to its HSS‑Co PM substrate and HARDLUBE coating.

How does the HARDLUBE coating affect performance?
HARDLUBE reduces friction and adhesion during cutting, which on the TECWERK tap lowers heat generation and helps maintain cutting edges for longer service life.

What length and shank dimensions does the tap have?
The tool is manufactured to DIN 371 overall length with a shank diameter of 4.5 mm, suitable for standard tapping holders and automated spindles.

Which tolerance and thread standard does the tap produce?
Threads are produced to the metric ISO profile (DIN 13 part 1) with tolerance class 6HX, providing a common industrial fit for general assembly applications.

Is the tool intended for through threads or blind holes?
The design includes a shearing chamfer for through threads, making the tap particularly effective for through‑hole applications where chip evacuation is required.
