12mm Cylindrical End Mill HSS-Co PM Alcrona-Coated 4-Flute Long, DIN 844 Weldon Shank - TECWERK

High wear resistance from the ALCRONA coating combined with the toughness of HSS‑Co PM delivers consistent performance in deep milling. The long DIN 844 Type N geometry with Weldon shank and unequal flute division reduces vibration and ensures secure clamping — order the cutter directly via Metav Werkzeuge or consult the team for specification support.

End mill DIN 844 Type N Ø12 mm – HSS‑Co PM, ALCRONA-coated (TECWERK)

The End mill DIN 844 Type N Ø12 mm is a long, four‑flute cutter designed for milling steels, stainless steel and cast iron at moderate cutting forces up to approx. 1000 N/mm²

• HSS‑Co PM for increased heat resistance
• ALCRONA coating for extended tool life
• Long DIN 844 Type N for deep milling
• 4 flutes with centre cutting for plunging
• Weldon shank with drive flat for secure clamping

High-performance cutting for demanding shop work

The long profile and DIN 844 geometry prioritise stable chip evacuation and predictable tool life in interrupted or plunge operations. Manufactured from HSS‑Co PM, the tool offers improved red hardness and toughness compared with conventional high-speed steels, which translates into fewer tool changes and more uptime on the machine. The ALCRONA coating reduces flank wear and helps maintain cutting-edge integrity during extended runs, so process stability and surface quality are maintained even when machining stainless materials and cast components.

Rigidity and clamping that support precision and safety

A Weldon shank with a drive flat provides a reliable mechanical interface for secure clamping in holders and chucks, limiting slippage under load. The end mill’s design emphasises tool stiffness through a tapered chip-groove root, which improves dimensional control and reduces chatter. Vibration is further mitigated by the deliberately unequal flute division, producing smoother cutting forces and a more consistent surface finish — a clear benefit for small-batch production and repair tasks where repeatability matters.

Material suitability and cutting behaviour explained

The cutter is optimised for materials with low to medium tensile strength up to about 1000 N/mm², showing very good performance on steels, stainless steel (INOX) and cast iron. Non-ferrous metals and special alloys are conditionally suitable, depending on machining parameters and fixture rigidity. With a centre cutting geometry and four flutes, the tool supports light plunge cuts and provides a balance between chip clearance and contact area, enabling controlled feeds for improved tool life and workpiece integrity.

Efficient application and machining recommendations

With an effective length that supports deeper pockets, the tool is best employed in stable setups with appropriate coolant or mist lubrication for stainless applications. The short cutting length relative to the overall profile helps reduce deflection during slotting and peripheral milling. When selecting feeds and speeds, account for the HSS‑Co PM material’s higher heat resistance by favouring moderate speeds and steady feed per tooth; this approach prolongs service life and keeps machining economical. Regular inspection of the ALCRONA wear layer will indicate when reconditioning or replacement is needed to maintain quality.

FAQ

What materials is this long end mill suitable for?
The TECWERK End mill DIN 844 Type N Ø12 mm is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys may be machined under adapted conditions.

Can the cutter perform plunge cuts or drilling operations?
Yes — the four‑flute, centre cutting geometry allows light plunge cutting; for sustained drilling, a dedicated drill is recommended.

How does the ALCRONA coating affect tool life?
The ALCRONA coating reduces adhesion and flank wear, extending tool life and improving consistency in demanding stainless and ferrous applications.

What clamping method ensures the best hold for deep milling?
A secure clamping system that engages the Weldon shank drive flat is recommended to minimise slippage and maintain the positional accuracy of the cutter.

Are there recommendations for feeds and speeds with this HSS‑Co PM tool?
Moderate speeds combined with a steady feed per tooth are advised to exploit the red hardness of HSS‑Co PM, prolonging service life and ensuring stable chip formation.
