Machine Tap DIN 376C GG M12×1.75 by TECWERK — HSS‑Co, TiCN-coated

The Machine Tap DIN 376C GG M12×1.75 is a straight-fluted metric tap engineered for reliable ISO thread production in a range of cast irons and similar materials.

• HSS‑Co substrate for high wear resistance
• TiCN coating for extended tool life
• 6HX tolerance for accurate thread fit
• Straight flutes for efficient chip evacuation

Consistent thread quality for cast materials

The tap is manufactured from HSS‑Co, a cobalt-alloyed high-speed steel that retains hardness at elevated temperatures, and it is TiCN-coated to reduce abrasion and adhesion. These material choices result in a stable cutting edge and longer service intervals, which benefits production runs where repeatability matters. Conforming to DIN 376C GG and producing M12×1.75 metric threads with a 6HX tolerance, the cutter delivers predictable fit and limited need for post-process rework, especially when working with grey or graphite cast irons.

Reduced downtime through controlled chip flow and geometry

Straight flutes and ground flanks combine to enable controlled chip evacuation and smooth engagement in both through and blind holes. The form C, type GG geometry is optimised for the brittle chip characteristics of cast materials, reducing the risk of chip packing and tap breakage. With a shank diameter of 9 mm, the tool integrates easily into standard collets and holders, maintaining concentricity and reducing set-up time. These design choices translate into higher first-pass yields and fewer tool changes on the shop floor.

Practical integration and workshop advantages

Supplied as a single unit with a clear identification ring, the tool supports straightforward inventory management and traceability. The combination of standardised DIN specification and the 6HX tolerance field facilitates interchangeability and compatibility with mating parts, which streamlines assembly and inspection procedures. For smaller workshops and industrial users alike, this tap offers a dependable balance of precision and longevity, helping to keep production schedules on track without complex adjustments.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap is suitable for grey cast iron, graphite cast iron and malleable (temper) cast iron, as specified for the DIN 376C GG geometry.

Can the tap be used for both through and blind holes?
Yes, the design supports both through-hole and blind-hole threading, with straight flutes helping to control chip formation in blind bores.

What does the 6HX tolerance indicate for the thread fit?
The 6HX tolerance denotes a slightly undersized internal tolerance class that provides a reliable clearance fit for standard metric screw threads, reducing the need for trial fittings.

Is the shank size suitable for standard tool holders?
With a 9 mm shank diameter, the tap fits common collets and holders, ensuring secure clamping and good concentricity during machine tapping.

How does the TiCN coating benefit everyday use?
The TiCN coating reduces friction and abrasive wear on the cutting edges, extending tool life and maintaining stable thread quality across longer production runs.
