M18x2.5mm Machine Tap DIN 376C HSS-Co TiN Coated 6H For Blind Holes, 14mm Shank - TECWERK

Take advantage of the HSS‑Co core and TiN coating for durable, high‑quality M18 threads; the right‑hand 40° helix and ISO2 (6H) tolerance ensure repeatable results for blind‑hole applications — order the tap directly via Metav Werkzeuge or ask our consultants if additional data is required.

TECWERK Machine Tap DIN 376C M18 x 2.5 HSS‑Co, TiN‑coated (6H)

The TECWERK Machine Tap DIN 376C M18 x 2.5 is a precision machine tap for producing ISO metric threads in blind holes, engineered for professional workshop and industrial use.

• HSS‑Co construction for high wear resistance
• TiN coating for extended tool life
• Designed for blind holes, ISO metric thread
• 14 mm shank, right‑hand 40° helix

Consistent thread quality and machining efficiency

The tap delivers consistent ISO metric threads thanks to the DIN 376C geometry and the specified ISO2 (6H) tolerance, which together reduce rework and ensure interchangeability in assemblies. Built from HSS‑Co (cobalt high‑speed steel), the tool resists heat and wear, enabling higher cutting speeds and longer service intervals compared with standard high‑speed steel. The TiN (titanium nitride) coating further improves durability by reducing friction and increasing resistance to abrasive wear, which translates into fewer tool changes and more efficient machining cycles. For production environments focused on throughput and repeatable accuracy, these combined features support stable process parameters and predictable results.

Material compatibility and application advantages

This tap is formulated for machining a wide range of steels, with a specified capability up to 1000 N/mm² tensile strength, making it suitable for common structural and engineering steels. The 40° right‑hand helix promotes efficient chip evacuation in blind‑hole tapping, minimising the risk of chip packing and thread damage; the helix angle is optimised to work with the relieved flanks for smooth cutting action. Compliance with DIN 13 Sheet 1 ensures standard thread form and pitch, while the Form C geometry offers a balance between strength and ease of tapping. These attributes make the tool a pragmatic choice where reliability and surface quality of the internal thread are priorities.

Handling, mounting and service considerations

The tap features a 14 mm shank, suitable for secure clamping in automatic tapping heads or collets, and is intended for use in machine tapping rather than hand tapping. The relieved flanks reduce cutting forces and facilitate smoother retraction, which helps protect both the workpiece and the tool in repetitive operations. For maintenance, the TiN coating permits easier cleaning of built‑up material and extends intervals between regrinds; when reconditioning is required, the HSS‑Co substrate accepts standard regrinding procedures. Documentation of the tool geometry and adherence to recommended machine parameters will prolong tool life and support predictable cycle times in production.

FAQ

What materials can be tapped with this machine tap?
The TECWERK machine tap is suitable for steels up to 1000 N/mm² and is designed to perform well in typical engineering steels thanks to its HSS‑Co construction and TiN coating.

Is this tap suitable for blind‑hole threading?
Yes, the tool is specifically designed for blind holes; the 40° right‑hand helix and relieved flanks aid chip evacuation and reduce the risk of chip build‑up.

What shank size is required to mount the tap?
The tap has a 14 mm shank diameter and is intended for secure mounting in suitable collets or automatic tapping heads.

Does the tool comply with recognised thread standards?
The tap conforms to DIN 376C thread form and DIN 13 Sheet 1 specifications, with an ISO2 (6H) tolerance for standardised fit and interchangeability.

Can the TiN coating be reconditioned or reground?
Regrinding is possible on the HSS‑Co substrate when required; reconditioning will remove the coating locally and should follow workshop regrinding procedures to restore geometry.
