TECWERK End mill DIN 844 Type NR — 25 mm, HSS‑Co5, TiCN coating, Weldon shank

The End mill DIN 844 Type NR, 25 mm, HSS‑Co5 with TiCN coating and Weldon shank is a short multi‑flute cutter engineered for precision milling of medium‑strength steels and cast iron in workshop and industrial settings.

• HSS‑Co5 substrate for improved toughness
• TiCN coating for extended tool life
• 25 mm diameter with 4 flutes
• Weldon shank for secure clamping

High cutting performance for medium-strength materials

The HSS‑Co substrate combined with a TiCN surface treatment delivers a balanced mix of toughness and wear resistance, allowing elevated cutting speeds compared with uncoated tools. The cutter conforms to DIN 844, providing a recognised geometry for reproducible results; its 25 mm diameter and 4 flutes enable stable cutting and efficient chip removal. Thanks to the coating, the tool can machine materials up to about 1,000 N/mm² when coated and up to 800 N/mm² uncoated, which translates into fewer tool changes and improved overall equipment effectiveness on medium‑strength steels.

Precision geometry and secure holding that reduce setup time

Engineered as a short, multi‑cutter profile with a Weldon shank, the tool ensures positive drive and minimal run‑out in holders that accept a TW/flat. The end geometry features a centre cut and a 45° chamfer to support reliable entry into the workpiece, while the hinterschliffenes cord profile (relieved cutting edges) helps maintain edge stability under load. With an effective cutting length of 63 mm and a relief length of 24 mm, the profile balances reach with rigidity, reducing chatter and the need for frequent re‑setting during batch production.

Application advantages and process recommendations

Designed chiefly for steel and cast iron — both listed as very well suited — the cutter also performs under conditional use for non‑ferrous metals, stainless steels and special alloys where appropriate feeds and speeds are selected. The right‑hand cutting orientation and short flute length favour robust slotting and peripheral milling operations in manual milling machines or CNC setups. For best life and surface finish, pair the tool with stable workholding, moderate axial engagement and coolant or air blast where aluminium or sticky materials are involved; the TiCN layer helps reduce built‑up edge and extends service intervals.

FAQ

What materials is this cutter best suited for?
The TECWERK end mill DIN 844 Type NR (SKU 2000866079NW) is very well suited for steel and cast iron; non‑ferrous metals, special alloys and stainless steels are conditionally suitable depending on cutting data.

How does the TiCN coating improve performance?
The TiCN coating on the TECWERK cutter increases surface hardness and reduces friction, which improves wear resistance and allows higher cutting speeds compared with uncoated HSS‑Co tools.

What are the key dimensions to plan toolholding and reach?
Key dimensions: 25 mm diameter, 25 mm shank, overall length 121 mm and effective cutting length 63 mm; the tool uses a Weldon TW driving flat for secure clamping.

Is the geometry suitable for slotting and face milling?
The short multi‑flute profile with a centre cut and a 45° chamfer supports both slotting and peripheral milling where rigidity and stable chip evacuation are required.
