TECWERK End Mill DIN 844 Type N Ø12 mm – HSS‑Co8, 4‑flute, Weldon shank

A TECWERK end mill intended for short, high‑rigidity milling tasks in workshops and small production runs, suitable for steels and cast iron where repeatable finish and secure clamping are required.

*HSS‑Co8 for improved wear resistance
*DIN 844 short design for compact set‑ups
*Weldon shank with drive flat for secure clamping
*Four flutes with centre‑cutting for axial plunging

Deliver higher throughput with durable cobalt HSS performance

The combination of HSS‑Co8 construction and a four‑flute geometry delivers a reliable balance between toughness and wear resistance, making the tool appropriate for continuous machining of medium‑strength steels. The tool data indicate a capability for uncoated operation up to 800 N/mm² and, where a suitable coating is applied, up to 1000 N/mm², which translates into longer tool life and fewer tool changes under comparable conditions. Explained simply: cobalt‑alloy high‑speed steel improves red hardness and flank wear behaviour, so production runs remain economical without sacrificing edge life or process stability.

Improve component quality through rigid short design and secure clamping

The short design increases stiffness at the cut and reduces chatter, while the Weldon shank with drive flat provides positive torque transmission in standard toolholders. These mechanical attributes work together to lower runout and maintain concentricity, which improves surface finish and tolerances even on interrupted cuts. The centre‑cutting geometry allows controlled axial entry for spot‑facing and plunge operations, reducing setup complexity and enabling multifunctional use of a single tool in compact machining cells.

Flexible suitability for shop workflows and material mixes

The tool is optimised for ferrous work: very good suitability for steel and cast iron is specified, with conditional use on non‑ferrous metals and stainless grades. This mix supports flexible tooling strategies where one cutter can serve several operations, lowering inventory without compromising capability. For specification queries or process matching, Metav Werkzeuge supplies technical advice and can assist with holder selection and suggested cutting parameters to integrate the cutter into existing tooling systems.

FAQ

Which materials does this end mill perform best on?
The TECWERK end mill (DIN 844 Type N, SKU 2000866334NW) is specified as very well suited for steel and cast iron; use on non‑ferrous metals and stainless steel is conditional depending on cut parameters and coating.

Can the cutter be used for plunge or spot‑facing operations?
Yes, the centre‑cutting geometry enables axial entry for plunge machining, making the tool suitable for spot‑facing and controlled plunge cuts in addition to peripheral milling.

How should the tool be clamped to avoid slippage and runout?
The Weldon shank requires a compatible holder or chuck with a clamping screw seating the drive flat; this arrangement secures axial and torsional transmission and reduces runout for improved surface finish.

Is the tool supplied coated, and what is the performance difference?
The provided data differentiates uncoated capability (up to 800 N/mm²) and an increased capability when coated (up to 1000 N/mm²); the exact coating type is not specified in the dataset.
