Machine tap DIN 371C – TECWERK M8 x 1.25 mm, HSS‑Co, TiN‑coated, 6H

The TECWERK machine tap M8 x 1.25 mm is a universal DIN‑371C tap designed for producing ISO metric internal threads in blind holes across a wide range of metals.

• Machine tap DIN 371C, universal design
• HSS‑Co material with TiN coating for wear resistance
• Right‑hand 40° spiral ideal for blind holes
• ISO metric M8 x 1.25, tolerance ISO2 (6H)
• Shank Ø 8 mm for secure machine clamping

High durability for demanding production runs

Constructed from HSS‑Co (cobalt high‑speed steel) and finished with a TiN coating, this tap delivers extended service life and stable cutting performance when machining tougher materials. The cobalt alloy increases hot‑hardness and resistance to abrasion, while the titanium nitride layer reduces friction and improves chip flow. The result is fewer tool changes and more predictable cycle times, supporting higher throughput on production machinery.

Clean chip control and superior thread quality in blind holes

The right‑hand 40° spiral geometry actively evacuates chips toward the flute, which is especially advantageous when forming threads in blind holes. Combined with the flank honing (flanks honed) the tool produces a finer thread surface and reduces the risk of burr formation. This geometry lowers the likelihood of tap breakage in interrupted cuts, enabling reliable threading even in interrupted or cast surfaces.

Consistent thread fit and interchangeability

Produced to the ISO metric profile and complying with DIN 13, sheet 1, the tap creates threads with the ISO2 (6H) tolerance field for internal threads, ensuring standardised fit and compatibility with commonly used bolts and fasteners. This precision reduces rework and guarantees consistent assembly behaviour across batches, making it suitable for components where repeatable fastening performance is required.

Machine‑ready design optimises setup and handling

The universal type with a shank diameter of 8 mm provides easy clamping in standard toolholders and collets, simplifying tool changes on CNC machines and tapping heads. The tool is specified for machining steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals, offering versatility across workshop and industrial applications. The green ring marking supports rapid visual identification of the tap grade on the tool trolley.

FAQ

What materials can this tap machine reliably cut?
The TECWERK machine tap M8 x 1.25 mm is specified for use in steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals, making it suitable for most workshop and industrial applications.

Is this tap suitable for blind holes only or also through holes?
The spiral 40° geometry and flank honing make this tap particularly effective for blind holes, but it can also be employed for through holes where the material and machine setup are appropriate.

How does the TiN coating benefit production?
The TiN coating on the TECWERK tap reduces friction and increases wear resistance, extending tool life and improving surface finish under continuous production conditions.

What tolerance and thread standard does the tap produce?
Threads are formed to the ISO metric profile in accordance with DIN 13, sheet 1, with an internal tolerance of ISO2 (6H) for consistent fit and interchangeability.

Can the tap be used in automated tapping heads or CNC machines?
Yes, the shank Ø 8 mm is compatible with common collets and holders, enabling secure clamping for automated tapping heads and CNC tool spindles.
