20mm Solid Carbide End Mill DIN 844 Type N 4-Flute Short, HSS-Co PM Alcrona Coating, Weldon Shank - TECWERK

Benefit from the combination of ALCRONA coating, HSS‑Co PM construction and a secure Weldon shank for durable, precise short‑length milling; order directly via Metav Werkzeuge or consult Metav specialists for tailored recommendations.

End mill DIN 844 Type N, 20 mm — HSS‑Co PM, ALCRONA‑coated (TECWERK)

A short TECWERK End Mill DIN 844 Type N designed for high‑quality milling of steels, stainless steel and cast materials up to approximately 1000 N/mm².

• ALCRONA coating for extended tool life
• HSS‑Co PM core for high toughness
• Weldon shank with drive flat for secure clamping
• Unequal flutes reduce vibration during milling

Durable cutting performance and extended tool life

The combination of HSS‑Co PM (powder‑metallurgy high‑speed steel) and an ALCRONA coating delivers a balance of toughness and wear resistance that supports longer tool life and reliable chip evacuation. Powder metallurgy provides a homogeneous carbide distribution for improved edge stability, while the coating reduces adhesion and surface wear under continuous operation. This results in fewer tool changes and more predictable machining cycles, which positively impacts throughput and production planning.

Rigidity and process stability for precise finishing

A Weldon shank with drive flat ensures secure clamping in standard toolholders, reducing slip and maintaining concentricity under load. The tool’s four‑flute configuration combined with a centre‑cutting geometry enables both peripheral milling and limited plunging. Vibration reduction is achieved through unequally divided flutes, while the conical flute root enhances overall tool stiffness. These design choices improve surface finish and dimensional consistency, particularly when machining medium‑strength steels and stainless steels.

Clear application range and machining advantages

Engineered to mill materials with low to medium strength up to roughly 1000 N/mm², the short version offers faster tool engagement and improved control in restrained setups. Suitability ratings highlight very good performance on steel, stainless steel and cast materials, with conditional use on non‑ferrous metals and special alloys. The right‑hand cutting orientation and centre‑cutting capability make the tool versatile for slotting and profiling tasks where a compact cutter length and robust geometry are required.

FAQ

What materials can this end mill machine effectively?
The TECWERK end mill is suited to machining steel, stainless steel and cast materials very well and is rated for materials up to approximately 1000 N/mm²; non‑ferrous metals and special alloys are conditionally suitable.

Is the cutter suitable for plunging operations?
Yes, the centre‑cutting geometry allows limited plunging as well as peripheral milling, making the cutter versatile for slotting and profiling tasks.

How does the ALCRONA coating improve performance?
The ALCRONA coating reduces adhesion and wear on the cutting edges, resulting in longer tool life and more consistent machining cycles for the TECWERK end mill.

What advantages does the Weldon shank provide?
The Weldon shank with a drive flat provides secure clamping and reduces the risk of slippage in the toolholder, supporting concentricity and process stability under load.

Are there measures to reduce vibration when milling?
Yes, unequal flute spacing reduces harmonic resonance and vibration, improving surface finish and dimensional accuracy during milling.
