3mm Cylindrical Shank End Mill Short 4-Flute HSS-Co8 Z=4 DIN 844, Centre Cutting, 6mm Shank - TECWERK

Taking advantage of the combination of HSS‑Co8 wear resistance, a compact 3 mm diameter for precise finishing, and the secure clamping of a Weldon shank ensures consistent short-reach machining results; order the tool via Metav Werkzeuge or consult the technical advisors for application guidance.

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

A TECWERK end mill DIN 844 Type N designed for precision short-reach milling in low to medium-strength materials and castings, offering centre-cut capability and secure Weldon clamping

• HSS‑Co8 for increased wear resistance
• DIN 844 Type N, short cutting length
• Four‑flute centre‑cut for axial plunge
• Weldon shank with drive flat for secure clamping

Precise cutting performance for tight, short-reach tasks

The combination of HSS‑Co8 alloy and a compact 3 mm cutting diameter delivers reliable edge retention and improved heat resistance during interrupted cuts. As a cobalt‑alloyed high‑speed steel, HSS‑Co8 maintains hardness at elevated temperatures and extends tool life compared with conventional HSS, which translates into fewer tool changes and steadier process times for production runs. Conformity to DIN 844 Type N provides a predictable geometry, enabling consistent results in reaming and finishing operations where tight tolerances are required. The four‑flute geometry balances chip evacuation with surface finish, while the centre‑cutting design allows axial plunging when pocketing or entering features without pre‑drilling.

Stable clamping and machining integrity for reproducible finishes

A short overall length and the Weldon shank with drive flat promote concentric clamping and secure torque transfer in collets and holders, reducing run‑out and vibration during milling. The specified 6 mm shank and the Weldon flat simplify tool changeover and maintain stability in high‑precision set‑ups, which benefits component repeatability. With a cutting length 4 mm and an effective length 8 mm, the cutter is optimised for shallow slots, finishing passes and confined spaces where longer tools would flex. The tool’s right‑hand cut is suitable for standard milling directions used in most conventional machining centres.

Application scope and workshop advantages

This short, four‑flute tool is particularly well suited for machining steel and cast iron, providing very good performance on these materials in typical workshop conditions; non‑ferrous metals and stainless steels are handled with conditional suitability depending on feed and speed. The tool is supplied uncoated, making it a cost‑effective choice for general finishing and one‑pass operations; coating options can increase surface strength for tougher applications. For toolrooms and production shops aiming to reduce tool variety without compromising on precision, the standardised geometry and robust material choice support a dependable, low‑complexity tooling strategy.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (DIN 844 Type N, SKU 2000866322NW) is very well suited for steel and cast iron; suitability for non‑ferrous metals and stainless steel is conditional and depends on machining parameters.

Can the cutter perform axial plunges?
Yes, the four‑flute centre‑cutting geometry of the TECWERK end mill allows axial plunging for pocket entry and plunge milling within the tool’s cutting length 4 mm.

What clamping system is recommended for stable operation?
Secure clamping using a Weldon‑compatible holder or appropriately sized collet that accommodates the 6 mm shank with drive flat is recommended to minimise run‑out and ensure torque transfer.

Is the tool supplied with a coating to extend performance?
The tool is supplied uncoated; while uncoated HSS‑Co8 performs well for many finishing tasks, applying a suitable coating can increase performance for higher‑strength or abrasive materials.

What standard ensures geometric consistency for tool replacement?
Conformance to DIN 844 Type N guarantees standardised geometry for predictable replacement and consistent machining results across production cycles.
