TECWERK machine tap MF26×1.5 HSS‑Co — DIN 374C, Form C

A TECWERK machine tap MF26×1.5 engineered for cutting metric fine threads in blind holes, suitable for medium‑to‑high tensile steels, temper castings and long‑chipping non‑ferrous metals

• HSS‑Co cobalt high-speed steel
• DIN 374C Form C geometry
• Right-hand 40° spiral for blind holes
• Shank Ø 18 mm for secure machine mounting

Robust material for extended service life and repeatable production

The use of HSS‑Co (cobalt high‑speed steel) provides increased heat and wear resistance compared with standard high‑speed grades, extending tool life in continuous production. The M26×1.5 metric fine thread form, combined with the DIN 374C specification, enables reliable repeatability across batches. For manufacturing environments where consistent thread quality and downtime reduction are priorities, this construction reduces the frequency of rework and tool changes. The result is a measurable improvement in process economy and component interchangeability.

Geometry and tolerance that secure precise, interchangeable threads

The Form C geometry with flank relief reduces side pressure on the thread flank and helps produce clean thread profiles. The tool is specified to DIN 13 with a tolerance field 6H, which corresponds to a standard engineering fit for internal threads and supports compatibility with mating parts. The right‑hand 40° spiral is optimised for blind‑hole tapping, promoting controlled chip evacuation and lowering the risk of chip packing in the blind end. These design choices increase surface quality and reduce the likelihood of thread distortion during tapping.

Machine compatibility and application scope for workshop and production use

With a shank diameter of 18 mm, the tap fits common machine holders and machining centres that accept solid shanks for direct mounting. The tool is rated for use in steels up to approximately 1000 N/mm² tensile strength, in temper cast iron and in long‑chipping non‑ferrous metals, making it suitable for maintenance, small‑series production and industrial assemblies. The solid construction and ground flank detail allow stable cutting behaviour under series conditions; when combined with appropriate speeds and lubricant choice, the tap supports efficient thread creation with minimal secondary finishing.

FAQ

What materials are suitable for this tap?
The TECWERK machine tap MF26×1.5 HSS‑Co is suitable for steels up to approximately 1000 N/mm², temper cast iron and long‑chipping non‑ferrous metals, as stated in the product data.

Is the tool suitable for blind‑hole tapping?
Yes — the right‑hand 40° spiral and Form C geometry are designed for blind‑hole threads, improving chip control and reducing the risk of chip blockage at the blind end.

What tolerance and standard are provided?
The thread is produced to DIN 13 with a tolerance field of 6H, providing a standard engineering fit for internal metric fine threads.

What machine mounting is required?
The tap has a shank diameter of 18 mm, compatible with machine holders and chucks that accept solid shank tools of that size.

Does this tap require a specific coolant or lubricant?
The TECWERK HSS‑Co construction benefits from appropriate cutting fluid or lubricant for the material being machined to support surface finish and tool life; selection depends on the workpiece material and machining conditions.
