20mm Solid Carbide End Mill HSS-Co PM ALCRONA Coating Weldon Shank 4-Flute Long, DIN 844 - TECWERK

Take advantage of a robust combination of HSS‑Co PM substrate and ALCRONA coating for extended tool life, plus a vibration‑reduced flute geometry that improves surface finish and dimensional stability; order the TECWERK end mill directly via Metav Werkzeuge or ask our consultants for machining parameters.

TECWERK HSS‑Co DIN 844 Type N End Mill D20 mm — ALCRONA‑coated, long Weldon shank

TECWERK HSS‑Co DIN 844 Type N End Mill D20 mm is a long, four‑flute right‑hand cutter designed for precision milling and partial plunging in steels, stainless steel and castings up to approx. 1000 N/mm²

• HSS‑Co PM with ALCRONA coating
• Long DIN 844 Type N, 4 flutes
• Weldon shank with centre cutting
• Vibration‑reduced, tapered core for rigidity

Greater tool life and consistent cutting performance

The use of HSS‑Co PM combined with the ALCRONA coating provides a balance of toughness and wear resistance that supports sustained machining cycles. This material and surface treatment reduce flank wear and heat buildup, which means fewer tool changes and more predictable batch processing. For operations that require repeatable surface quality, the ALCRONA layer helps maintain cutting geometry and prolongs service intervals, delivering measurable uptime benefits in production environments.

Stability for long‑reach milling and improved surface quality

A long‑reach configuration with a tapered core increases bending resistance compared with standard long cutters, translating into better dimensional control on extended overhangs. The tool’s flute layout delivers vibration reduction through unequal flute division, lowering chatter and improving finish on each pass. The result is reduced rework and fewer rejected parts when working on deep slotting or shoulder milling in medium‑strength steels.

Secure clamping and effective chip evacuation

The Weldon shank with drive flat ensures reliable retention in chucks and holders, making the cutter suitable for higher radial loads. With 4‑flute geometry and a centre‑cutting point, the cutter allows limited plunging and provides efficient chip packing for interrupted cuts. Right‑hand cutting and the effective flute profile support stable feeds and moderate cutting speeds, keeping cycle times efficient while maintaining surface integrity.

Clear application limits and practical advice

The cutter is specified for machining materials up to approximately 1000 N/mm² and is very well suited to steel, stainless steel and castings; non‑ferrous metals and special alloys are conditionally suitable. For unfamiliar material grades or unusual setups, consult cutting data to match speeds and feeds with the tool’s effective length and overhang.

FAQ

What materials is the cutter suitable for?
The TECWERK HSS‑Co DIN 844 Type N end mill (SKU 2000866051NW) is very well suited to steel, stainless steel and castings up to approx. 1000 N/mm²; non‑ferrous metals and special alloys are conditionally suitable.

Can this cutter perform plunging operations?
Yes — the centre‑cutting geometry allows limited plunging, so the cutter can enter the material axially for spot‑drilling or short plunge cuts; however, plunging performance is best when kept within the specified cutting length and appropriate feeds.

Which toolholder suits the shank?
The Weldon shank with drive flat is designed for secure clamping in Weldon holders and setscrews, providing positive torque transmission and reliable retention under radial loads.

How does the vibration‑reduced geometry help production?
Unequal flute division reduces harmonic excitation, which minimises chatter, improves surface finish and often extends tool life — especially beneficial when machining long projections or deep slots.

Are there recommended speeds and feeds?
Recommended cutting data depend on material, depth of cut and machine rigidity; Metav Werkzeuge can provide tailored parameters for the TECWERK end mill (SKU 2000866051NW) based on the specific application.
