End mill DIN 844 Type HR, Ø20 mm – HSS‑Co PM, ALCRONA coated (TECWERK)

The End mill DIN 844 Type HR is a short, 4‑flute milling cutter designed for high‑strength steels and stainless materials, optimised for medium‑duty slotting and finishing operations.

• ALCRONA coating for extended tool life
• Powder‑metallurgy HSS‑Co for toughness
• Weldon shank with drive flat for secure clamping
• Centre‑cutting, 4‑flute short design

Higher throughput through improved cutting performance

The short, 4‑flute geometry combined with HSS‑Co PM material delivers a balance of toughness and wear resistance that suits interrupted cuts and demanding shopfloor conditions. The ALCRONA coating reduces built‑up edge and friction, which extends tool life and stabilises cutting forces; this translates into fewer tool changes and higher machine uptime. For production planners, this means measurable efficiency gains without compromising surface quality.

Repeatable precision and confident toolholding

A Weldon shank with drive flat and nominal Ø20 mm shank diameter provide reliable torque transmission and repeatable concentricity in standard holders. The centre‑cutting design enables limited plunge cuts, while the effective length 52 mm and overall length 104 mm suit compact tool setups. Compliance with DIN 844 Type HR ensures the geometry and tolerances meet recognised workshop standards, making tool selection and fixture planning straightforward.

Suited materials and robust construction for tough applications

Engineered for machining materials up to approximately 1400 N/mm², the cutter is rated very good for steel, stainless steel and cast materials, and conditionally suitable for non‑ferrous metals and special alloys. An improved stiffness results from the conical flute root, which reduces deflection during side milling and finishing, enhancing dimensional accuracy. The combination of HSS‑Co PM and ALCRONA coating also reduces wear on edges, helping to preserve profile and surface finish over longer tool lives.

Practical advantages for workshop and production use

The short variant simplifies tool management in cells with limited clearance while maintaining cutting reliability. A right‑hand cutting direction matches conventional spindle rotation, and the balanced four‑flute layout supports fine surface quality in slotting and light profiling. For procurement and maintenance teams, the robust design means predictable replacement intervals and easier inventory planning, contributing to a stable production rhythm.

FAQ

Is this cutter suitable for plunge cutting?
The End mill DIN 844 Type HR is centre‑cutting, so limited plunge operations are possible; for full-depth plunging, follow machine and process guidelines.

Which materials does the cutter handle best?
TECWERK’s HSS‑Co PM end mill performs very well on steels, stainless steel and cast materials and is conditionally suitable for non‑ferrous metals and special alloys up to ~1400 N/mm².

What clamping system is recommended?
Use a secure holder compatible with a Weldon shank and ensure the drive flat is engaged for consistent torque transmission and repeatable concentricity.

How does the ALCRONA coating benefit machining?
The ALCRONA coating reduces friction and adhesion, improving edge life and surface finish, which lowers the frequency of tool changes in production.

Can this cutter be used for finishing passes?
Yes; the 4‑flute geometry and conical flute root provide good surface quality and stiffness suitable for finishing light to medium cuts.
