TECWERK Shank End Mill (DIN 844 Type N, D 12 mm) — HSS‑Co8, long 4‑flute milling cutter

The TECWERK shank end mill is a long, centre‑cutting HSS tool designed for robust milling of steel and cast components in general workshop and production environments.

• HSS‑Co8 for improved heat resistance
• DIN 844 Type N long version
• 4 flutes, centre‑cutting for axial plunging
• Weldon shank with drive flat for secure clamping

High‑temperature resistance for consistent steel machining

The tool is made from HSS‑Co8, a high‑speed steel alloy with 8% cobalt that increases red hardness and wear resistance compared with conventional HSS. This material composition enables stable cutting performance when machining medium‑strength steels: the uncoated tool is rated for materials up to 800 N/mm², while coated variants can extend that capability toward 1200 N/mm². The result is reduced edge wear, fewer tool changes and more predictable cycle times — a clear efficiency gain for serial production and repair work.

Precise axial plunging and reliable surface finish

A centre‑cutting geometry combined with 4 flutes allows for safe axial plunging and good load distribution across the cutting edges. The four‑flute layout balances surface finish and chip control for finishing passes in steels and castings, producing uniform surfaces with lower hand‑fettling. For users familiar with milling terminology: centre‑cutting means the tool can enter material axially without pre‑drilling, while the flute count is a trade‑off between chip space and finish quality — here optimised for metalworking tasks.

Secure holding and toolholder compatibility

Conforming to DIN 844 Type N, the long shank and Weldon shank with a drive flat provide a predictable interface with standard toolholders and clamping systems. The cylindrical shank with dedicated drive flat reduces slippage in high‑torque cuts and simplifies changeover. The cutter is right‑hand cutting by design, matching customary spindle rotation and feed directions in most milling centres and manual mills, which helps maintain consistent cutting forces and part tolerances.

Ready for workshop production with clear material guidance

Application data shows very good suitability for steel and cast components, while non‑ferrous metals and stainless steels (INOX) are conditionally workable depending on feed, speed and coolant strategy. Choosing appropriate cutting parameters and, where beneficial, a suitable coating will extend tool life and increase productivity. Metav’s approach to precision makes high‑quality measuring and tooling affordable: with a broad product range and decades of experience, Metav Werkzeuge supports selection and integration to keep production reliable and procurement simple.

FAQ

Can this end mill plunge directly into the workpiece?
Yes. The tool features a centre‑cutting geometry that allows axial plunging without prior drilling for many steels and cast materials, provided appropriate feeds and speeds are used.

What materials is the cutter best suited to?
The TECWERK shank end mill is very well suited for steel and cast components; non‑ferrous metals and stainless steels are conditionally workable depending on cutting data and coolant.

Does the tool require a special toolholder?
No special holder is required; the Weldon shank with drive flat fits standard Weldon clamping systems and ensures secure holding under typical milling loads.

Is the tool coated?
The supplied tool is identified as HSS‑Co8 and uncoated; coating can increase the upper strength range (up to approximately 1200 N/mm²) when a coated variant is selected.

What is the article number for ordering and reference?
The article number is 2000866382NW; use this SKU when requesting the TECWERK long shank end mill to ensure the correct item is supplied.
