End mill DIN 844 Type HR, 25 mm, 63 mm cutting length (HSS‑Co5, TiCN, Weldon shank) — TECWERK

The end mill DIN 844 Type HR, 25 mm is a short, four‑flute HSS‑Co5 milling cutter with TiCN coating and Weldon shank, designed for high‑performance machining of steel and cast iron in workshop and production environments.

• HSS‑Co5 core with TiCN coating
• Weldon shank for secure clamping
• DIN 844 Type HR, four‑flute design
• Very good for steel and cast iron

High‑performance cutting for demanding materials

The end mill DIN 844 Type HR, 25 mm is manufactured from HSS‑Co5, providing a favourable balance between toughness and hardness for interrupted and continuous cuts. The TiCN coating increases wear resistance and thermal stability; with a coated tool the cutter is suitable for machining materials up to approximately 1200 N/mm², whereas an uncoated variant is indicated up to around 800 N/mm². This combination reduces flank wear and extends service life, which supports higher productivity and steadier component quality in serial and single‑part production.

Precision geometry for consistent surface quality

The DIN 844 Type HR four‑flute geometry and centre cutting capability permit reliable plunge operations and efficient slotting, while the hinterschliffenes feines Kordelprofil (fine, relieved cord profile) promotes controlled chip breakage and an improved surface finish. A 45° protection chamfer reduces edge chipping at entry, and the cylindrical shank with drive flat is supplied as a Weldon (TW) shank for positive drive and repeatable concentricity. These design features are intended to produce consistent tolerances and minimise setup time in batch processing.

Practical application and workshop integration

Short overall length and robust core material make this cutter well suited to finishing and medium‑duty roughing tasks where rigidity and chip control are decisive. Suitability is specified as very good for steel and very good for cast iron, with conditional applicability for non‑ferrous metals, stainless steels and special alloys; selection should match part requirements and machining strategy. Handling is simplified by the Weldon shank for secure clamping, and the TiCN coating supports longer intervals between tool changes, reducing downtime and tool inventory turnover.

FAQ

Is this cutter suitable for plunge milling?
The end mill DIN 844 Type HR, 25 mm features centre cutting, which permits plunge operations; the four‑flute geometry and TiCN coating further support controlled chip evacuation and stability during plunging.

What materials can be machined with this TECWERK cutter?
This TECWERK HSS‑Co5 cutter is specified as very good for steel and very good for cast iron, with conditional suitability for non‑ferrous metals, stainless steels and special alloys; selection should be based on component hardness and machining strategy.

Does the TiCN coating improve tool life significantly?
Yes, the TiCN coating increases wear resistance and thermal stability; a coated tool is indicated for materials up to approximately 1200 N/mm², which extends service life compared with an uncoated variant.

How is the tool secured in the machine?
The cutter is supplied with a Weldon shank (TW) and drive flat for secure clamping and repeatable concentricity, suitable for standard collet or chuck systems that accept Weldon‑style shanks.

What is the exact article number for ordering?
The article number for this TECWERK end mill is 2000866083NW, which should be quoted when inquiring or ordering through Metav Werkzeuge.
