TECWERK End Mill DIN 844 Type N, Ø 3 mm — HSS‑Co8, 4‑flute, Weldon shank

A TECWERK end mill designed as a long‑reach Type N cutter for precision milling and moderate plunge work in steel and cast materials.

• HSS‑Co8 high‑speed steel for increased red hardness
• DIN 844 Type N long series, centre cutting
• 4‑flute geometry for smooth chip evacuation
• Weldon shank Ø 6 mm with drive flat

Precise reach and cutting geometry for narrow slots and pockets

The long‑series Type N geometry, compliant with DIN 844, provides extended reach while maintaining rigidity for fine detail milling. With a Ø 3 mm cutting diameter and 12 mm effective length, the tool lets operators machine narrow slots and internal features without frequent tool changes. The 4‑flute design balances chip removal and surface finish, making the cutter suitable for finishing passes where dimensional accuracy and edge quality matter.

Material performance and where the tool excels

Manufactured from HSS‑Co8, the cutter offers enhanced hot hardness and toughness compared with standard high‑speed steels, which improves performance when cutting materials up to approximately 800 N/mm² in tensile strength with an uncoated tool. The tool is very well suited for steel and castings, and can be used for non‑ferrous and stainless materials with caution; centre‑cutting capability allows limited plunging operations without the need for a separate drill.

Secure clamping and machine compatibility for productive workflows

A Weldon shank with a 6 mm diameter and drive flat ensures positive gripping in standard collets and Weldon holders, reducing the risk of slippage under higher axial loads. The cylindrical shank form provides compatibility with common toolholders in bench mills and general machining centres, simplifying tool inventory and enhancing setup reliability across jobs.

Operational benefits: reliability, surface quality and process economy

The combination of HSS‑Co8 material and right‑hand cut geometry delivers consistent chip formation and predictable tool life in everyday workshop use. For operations requiring repeatability and reduced downtime, the tool’s long‑reach profile minimises the need for special extensions while the four cutting edges distribute wear, allowing multiple regrinds when required and therefore lowering total cost of ownership in routine production.

FAQ

Is this cutter suitable for plunge milling?
The TECWERK end mill is centre cutting, so limited plunge operations are possible; for sustained drilling a dedicated drill is recommended.

What materials can be machined with this tool?
Made of HSS‑Co8, the cutter is very well suited to steel and castings, with conditional suitability for non‑ferrous and stainless materials depending on cutting parameters.

Can the tool be used in a Weldon holder?
Yes, the tool features a Weldon shank with a drive flat and a 6 mm shank diameter for secure clamping in Weldon holders.

How does the 4‑flute geometry affect finish and feed rates?
A 4‑flute geometry improves surface finish and allows slightly higher feed per tooth in finishing passes while maintaining good chip control in moderate depth cuts.

Is any coating applied to increase performance?
This item is supplied uncoated; performance figures are based on the uncoated HSS‑Co8 tool (suitable up to ~800 N/mm²). Coated versions would extend the application range.
