End mill DIN 844 HR, 20 mm — TECWERK, ALCRONA-coated, HSS‑Co PM, 4‑flute

A End mill DIN 844 HR, 20 mm designed as a long, centre-cutting tool for robust slotting and profile milling in high-strength steels and stainless steels

• HSS‑Co PM core for high thermal stability
• ALCRONA coating for extended tool life
• Weldon shank with drive flat for firm clamping
• Long 4‑flute design for deep slotting and profile milling

Durable performance for demanding materials

The combination of a HSS‑Co PM substrate and ALCRONA surface treatment delivers a measurable advantage in wear resistance and heat tolerance. Powder-metallurgy cobalt steel increases toughness and reduces chipping risk under interrupted cuts, while the ALCRONA coating lowers friction and delays flank wear; this translates into longer tool life and more stable cycle times when machining hard or abrasive workpieces. The DIN 844 specification ensures the tool geometry and tolerances conform to recognised industry standards, supporting reproducible results across production batches.

Secure clamping and rigid tool geometry for consistent finishes

Designed with a Weldon shank and a cylindrical shank with a drive flat, the cutter offers positive torque transmission and dependable repeatability in powered toolholders. The long version with an effective length 89 mm provides extended reach without compromising stiffness, helped by the tapered flute root which improves rigidity and reduces chatter. A centre-cutting geometry allows controlled plunge capability, while the 4‑flute layout balances chip evacuation and surface integrity for precise profile milling and slotting operations.

Broad suitability and practical machining guidance

This long end mill is optimised for materials up to approximately 1400 N/mm² tensile strength: steel and stainless steel (INOX) are particularly well suited, while non-ferrous metals and special alloys are machinable under adapted feeds and speeds. The tool is right‑hand cutting and features a 45° protective chamfer to shield the cutting edges during entry. For best results in production, pair the cutter with appropriate coolant and use conservative entry moves when working with conditionally suitable alloys to extend service life and maintain dimensional accuracy.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (End mill DIN 844 HR, 20 mm, SKU 2000866077NW) is very well suited for steel and stainless steel (INOX) and can machine cast materials effectively; non‑ferrous and special alloys are conditionally suitable with adjusted parameters.

Is the tool suitable for plunge milling?
Yes. The centre‑cutting geometry of this HSS‑Co PM cutter permits controlled plunge operations, making it appropriate for pocketing and entry moves when using correct feeds and speeds.

How does the ALCRONA coating benefit production?
The ALCRONA coating reduces friction and improves wear resistance, allowing higher sustained cutting performance and longer tool life under typical workshop cooling regimes.

What clamping system is recommended for reliable performance?
Use a secure clamping system that accommodates a Weldon shank with drive flat to ensure positive torque transmission and minimise slippage during heavy cuts.

Can this tool handle interrupted cuts or tough machining conditions?
The HSS‑Co PM substrate increases toughness and resistance to chipping, so the cutter performs reliably in interrupted cuts and demanding milling tasks when set-up and cutting data are appropriate.
