Machine tap M27×3 mm (DIN 376C) – HSS‑Co, nitrided and vapour‑treated (TECWERK)

Machine tap M27×3 mm (DIN 376C) is a high‑performance cutting tool designed for producing metric ISO threads in stainless, acid‑ and heat‑resistant steels, optimised for blind‑hole applications.

• HSS‑Co construction for extended tool life
• Suitable for blind holes (DIN 376C)
• ISO2 tolerance (6H) for precise threads
• Nitrided and vapour‑treated surface

Precision that keeps production on target

The HSS‑Co substrate combined with the DIN 376C geometry delivers consistent thread form and dimensional accuracy for metric ISO threads such as M27×3 mm, reducing the need for rework. The tool conforms to DIN 13, sheet 1, and the ISO2 (6H) tolerance field ensures threads meet standardised fits for assemblies. For manufacturing environments where reproducible results are essential, this geometry minimises variation between cycles and supports stable process control, enabling predictable assembly performance and lowering scrap rates.

Surface treatment and geometry engineered for difficult materials

A nitrided and vapour‑treated surface provides enhanced surface hardness and abrasion resistance, which is particularly effective when machining stainless, acid‑ and heat‑resistant steels with tensile strengths above 850 N/mm². The 40° right‑hand spiral assists chip control in blind holes by directing chips away from the cutting edge, while flank relief (ground flanks) reduces cutting forces and promotes smoother thread formation. The combination of these features makes the tool suitable for demanding alloys where conventional taps would blunt prematurely, thereby lengthening in‑service life and improving process uptime.

Shop‑floor benefits and handling features that save time

Operational advantages include a recognisable blue ring for rapid tool identification and a 20 mm shank for secure clamping in standard machine holders. The relief‑ground flanks lower torque peaks during cutting, which translates to reduced machine load and more predictable tool behaviour across batches. Compliance with standard thread specifications simplifies quality assurance and documentation, while the robust construction and surface treatment reduce tool change frequency. Together, these aspects support leaner tool inventories and more efficient production scheduling.

FAQ

What materials is this tap intended for?
The TECWERK machine tap is designed for stainless, acid‑ and heat‑resistant steels and is specified for materials with tensile strength above 850 N/mm².

Can this tap be used for blind holes?
Yes, the tool follows DIN 376C geometry and is optimised for blind‑hole threads, with a 40° spiral that aids chip evacuation.

What tolerance and thread standard does the tool produce?
Threads are produced to metric ISO specifications per DIN 13 sheet 1, with a tolerance field of ISO2 (6H) for consistent assembly fits.

How is the tap identified in the tool rack?
Identification is simplified by a blue ring marking, allowing fast visual selection of the specified thread type.

What clamping shank is required?
A 20 mm shank diameter is specified for secure clamping in standard machine holders suitable for cutting‑tool applications.
