12mm Cylindrical Shank Long Solid Carbide-Backed HSS-Co End Mill, ALCRONA Coating, DIN 844 Z4 110mm - TECWERK

Take advantage of the combination of HSS‑Co tool steel, ALCRONA coating and a long DIN 844 Type N geometry for consistent chip evacuation and extended service life; order the TECWERK HSS‑Co PM long end mill (Ø12 mm) directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK HSS‑Co PM long end mill Ø12 mm, DIN 844 Type N, 4‑flute

The TECWERK HSS‑Co PM long end mill is a long, centre‑cut milling cutter designed for precision milling of steels, stainless steels and cast materials in general machining applications.

• HSS‑Co PM with ALCRONA coating
• DIN 844 Type N long end mill
• 4‑flute design for smooth material removal
• Unequal flute spacing for vibration reduction

Precision machining of medium‑strength steels for predictable results

The TECWERK HSS‑Co PM long end mill combines HSS‑Co substrate and ALCRONA coating to deliver a tool that keeps cutting geometry stable under load. The DIN 844 Type N profile and Ø12 mm diameter support repeatable slotting and peripheral milling operations where dimensional accuracy matters. For production environments that prioritise consistent tolerances and low scrap rates, the cutter’s long version and centre‑cut capability help maintain process stability when machining shoulders and deeper pockets, while the material choice ensures resistance to thermal softening during interrupted cuts.

Longer tool life and improved surface finish through coating and substrate

A powder‑metallurgy high‑speed cobalt alloy (HSS‑Co PM) is more wear‑resistant than conventional HSS; the ALCRONA coating further reduces abrasive wear and adhesion of workpiece material. The result is extended tool life and higher first‑pass surface quality with fewer regrinds. For operations where tool change frequency affects throughput, this combination reduces downtime and total cost per component by maintaining sharp cutting edges over longer production runs. Coating also aids in chip flow and heat control, which benefits tool life and workpiece integrity.

Stable cutting performance with reduced vibration and secure clamping

The cutter’s 4 flutes increase material removal rate while maintaining surface integrity, and the unequal flute spacing actively contributes to reduced vibration, resulting in quieter operation and less chatter on thin walls or long overhangs. A Weldon shank with drive flat ensures reliable clamping in the toolholder and prevents slippage under torque. The tool’s 63 mm effective length and generous overall length optimise reach without compromising stiffness; this geometry improves rigidity and reduces deflection in restricted setups, making complex profiles more achievable with fewer passes.

Recommended uses and compatibility with common workshop materials

The geometry and material pairing make this long end mill particularly suitable for steel, stainless steel (inox) and cast iron, offering very good performance in those materials while remaining conditionally suitable for non‑ferrous alloys and special alloys. The centre cut feature allows limited plunge cuts and reduces the need for pre‑drilling in many profiling tasks. Given the specified 4 mm cutting length and the overall dimensions, this cutter is ideal for slotting, contouring and finishing operations where the combination of reach and precision is required. For best results, select clamping and spindle speeds appropriate to the workpiece and machine rigidity.

FAQ

What materials is this long end mill best suited for?
The TECWERK HSS‑Co PM long end mill (DIN 844 Type N, Ø12 mm, SKU 2000866047NW) is very well suited to steel, stainless steel (inox) and cast iron; it is conditionally suitable for non‑ferrous and special alloys.

Can the cutter perform plunge cuts?
Yes, the centre‑cut geometry allows limited plunge cutting; the TECWERK long cutter is designed for combined slotting and profiling operations where intermittent plunges are required.

How does the ALCRONA coating improve performance?
The ALCRONA coating reduces abrasive wear and adhesion, improving HSS‑Co tool life and helping to maintain surface finish over extended runs for the TECWERK cutter.

Does this tool require a specific holder type?
A secure toolholder with a Weldon‑style clamping system is recommended to engage the Weldon shank drive flat and prevent slippage during heavy machining.

What are the dimensional key values for setup planning?
Key values: Ø12 mm diameter, 110 mm overall length, 63 mm effective length and 4 mm cutting length for the TECWERK long end mill (SKU 2000866047NW).
