End mill DIN 844 Type HR, 8 mm, HSS‑Co PM, ALCRONA coated — TECWERK

The End mill DIN 844 Type HR D8 mm is a long, 4‑flute HSS‑Co end mill with centre cut and Weldon shank, designed for machining steels and stainless steel up to approximately 1400 N/mm².

• PM HSS‑Co body with ALCRONA coating
• Weldon shank with drive flat for secure clamping
• Centre‑cut geometry for limited plunging
• Long reach with improved stiffness
• Very good for steel and stainless steel

Precise material pairing for consistent results

The tool combines PM HSS‑Co metallurgy with an ALCRONA surface treatment to deliver enhanced wear resistance and thermal stability during interrupted cuts. Conforming to DIN 844 and specified as Type HR, the geometry is optimised for cutting forces typical of steels and INOX with tensile strengths up to ~1400 N/mm². The combination of powder‑metallurgy steel and hard coating reduces flank wear and extends tool life, meaning more consistent part tolerances and fewer tool changes over a production run.

Robust design that keeps machining stable

A Weldon shank with a 10 mm drive flat and a 45° protective chamfer secure the tool under heavy feed and rapid direction changes. The centre‑cut capability allows direct plunging for short depths, while the 4‑flute layout balances chip evacuation and radial stiffness. With an effective length of 44 mm and an overall length of 88 mm, the long‑reach profile plus a conical flute root improves bending stiffness, reducing chatter risk and producing superior surface finish in through‑slot and shoulder milling operations.

Productivity advantages in the workshop or on the shop floor

The cutter’s short cutting length of 4 mm and the geometry tuned for right‑hand cutting help to keep forces predictable and cycle times stable. Tool life gains from the ALCRONA layer and HSS‑Co PM substrate translate into lower tooling consumption and less downtime for replacements. Suitability ratings indicate the cutter is very good for steel, stainless steel and cast materials, and conditionally suitable for non‑ferrous and special alloys — a practical choice where a single tool must cover a range of medium‑duty tasks while delivering repeatable quality and efficiency.

FAQ

What materials is the TECWERK end mill suitable for?
The TECWERK end mill is rated very good for steel, stainless steel and cast materials and conditionally suitable for non‑ferrous metals and special alloys; suitable up to around 1400 N/mm² tensile strength.

Can this tool perform plunging operations?
Yes, the centre‑cut geometry enables limited plunging and helical entry; the end mill is specified as centre‑cut to allow direct engagement where necessary.

What is the shank type and how is it clamped?
The cutter features a Weldon shank with a 10 mm drive flat to ensure secure clamping and reliable torque transmission in standard toolholders.

How does the ALCRONA coating help in production?
ALCRONA coating increases wear resistance and reduces built‑up edge tendency, which lengthens tool life and maintains surface quality under higher temperatures and interrupted cuts.

Which standard does this cutter follow?
The tool conforms to DIN 844, Type HR, specifying dimensions and tolerances for long straight‑flute end mills.
