12mm Solid Carbide End Mill DIN 844 Type N 4-Flute Long With Centre Cut, ALCRONA Coating - TECWERK

Benefit from the combination of HSS‑Co PM construction, ALCRONA coating and a secure Weldon shank for long‑reach milling with reduced vibration — order the TECWERK end mill directly via Metav Werkzeuge or consult our specialists for tailored advice.

End mill DIN 844 Type N, 12 mm – HSS‑Co PM, ALCRONA‑coated (TECWERK)

The End mill DIN 844 Type N, 12 mm is a long, four‑flute, centre‑cutting tool engineered for robust milling of steels, stainless steels and cast iron in workshop and CNC environments.

• HSS‑Co PM with ALCRONA coating
• Four flutes with centre‑cutting geometry
• Weldon shank with drive flat
• Unequal flute spacing reduces vibration

Reliable wear resistance for extended service life

The long version of this DIN 844 Type N cutter combines HSS‑Co PM metallurgy with an ALCRONA coating to improve wear resistance and thermal stability in continuous milling. The powder‑metallurgy high‑speed steel matrix offers a fine microstructure for consistent edge retention, while the coating reduces adhesion and abrasion during interrupted cuts. These properties translate into fewer tool changes and a steadier process, particularly when machining demanding materials up to ~1000 N/mm² tensile strength.

Secure clamping and efficient chip control for precise results

A Weldon shank with a dedicated drive flat ensures torque transmission and secure clamping in standard toolholders, reducing the risk of slippage during heavy cuts. The four‑flute geometry balances material removal and surface finish, and the centre‑cutting design enables plunge milling when required. For long‑reach operations, the combination of secure shank fixation and optimised flute geometry supports both accuracy and repeatability on the machine.

Geometry tailored to vibration reduction and rigidity

The cutter features unequal flute spacing to break harmonic oscillations and reduce chatter, while the tapered flute root increases local stiffness and improves resistance to deflection. These design choices enhance surface quality and dimensional control in profile and slotting work. The tool is right‑hand cutting and benefits from the improved rigidity to maintain concentricity and minimise tool wear in continuous production runs.

Suitable applications and material guidance

This long end mill is very well suited for steel, stainless steel and cast iron, while non‑ferrous metals and certain special alloys are conditionally suitable depending on cutting parameters and coolant strategy. The centre‑cutting capability makes it appropriate for pocketing, plunge operations and through‑slotting where access is limited. For demanding jobs, pair the cutter with appropriate spindle speeds and feeds recommended by tooling charts and verify clamping torque to maintain process stability. Metav’s quality filter in Emmerich ensures consistent product checks before dispatch, supporting reliable supply for workshop and industrial use.

FAQ

What materials is this end mill suitable for?
The TECWERK End mill DIN 844 Type N, 12 mm is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and some special alloys are conditionally suitable depending on cutting data.

Can the cutter perform plunge milling?
Yes — the centre‑cutting geometry allows plunge operations, so the tool can be used for pocketing and through‑slotting in addition to conventional side milling.

What type of shank does the tool use for clamping?
The cutter features a Weldon shank with a drive flat to ensure secure clamping and reliable torque transmission in standard toolholders.

How does the ALCRONA coating benefit machining?
The ALCRONA coating reduces adhesion and abrasion on cutting edges, improving wear resistance and thermal performance during continuous or interrupted milling.

What design features reduce vibration and improve finish?
Unequal flute spacing and a tapered flute root increase stiffness and interrupt harmonic oscillations, which reduces chatter and enhances surface quality.
