TECWERK HSS‑Co5 end mill (DIN 844) — 12 mm, TiCN coated, Weldon shank

The TECWERK HSS‑Co5 end mill is a short, four‑flute cutter designed for precision milling of steels and cast iron in general workshop and industrial settings

• TiCN coating for extended tool life
• HSS‑Co5 core for heat resistance
• Four flutes for high material removal
• Weldon shank with drive flat

High cutting performance for demanding steels

This cutter combines a HSS‑Co5 substrate with a thin TiCN surface layer to extend tool life while maintaining sharp cutting edges. The short configuration and four flutes enable stable cutting at moderate feeds and speeds, providing a balance between material removal rate and tool life. With a 12 mm diameter and an effective length of 36 mm, the tool supports interrupted and continuous cuts typical in jobbing and production work. The specification allows machining of workpieces up to 800 N/mm² with the uncoated geometry and up to 1200 N/mm² when used with the coated variant, giving clear guidance on suitable applications.

Geometry engineered for chip control and surface quality

The cutter’s geometry—including a 45° chamfer, centre cutting capability and a fine, relieved cord profile—promotes predictable chip formation and reduces the tendency to rub on the bore. The precise relief profile minimises built‑up edge and improves finish on the machined surface. These design choices reduce rework and increase first‑pass yield, a direct contributor to lower per‑part costs and improved cycle reliability. The short HR type configuration ensures rigidity at the cutting edge, helping to maintain tolerances in lighter setups and when using manual or smaller CNC machines.

Workshop compatibility and straightforward handling

A Weldon shank with drive flat delivers secure clamping and positive torque transmission in standard toolholders, simplifying tool changes and preventing slippage during heavy cut conditions. Conforming to DIN 844, the cutter fits common tooling systems and simplifies inventory management. Suitability notes indicate steels: very good and cast iron: very good, while non‑ferrous metals, stainless steels and certain special alloys are conditionally suitable; this makes the tool a reliable choice for mixed‑workshop environments where steel and cast parts predominate. Clear specification reduces selection risk and supports consistent procurement decisions.

FAQ

What materials is this end mill best suited for?
The TECWERK HSS‑Co5 end mill (DIN 844, SKU 2000866512NW) is rated very good for steels and cast iron; non‑ferrous metals, stainless steels and special alloys are conditionally suitable.

Can this cutter be used for plunge cutting or drilling operations?
The tool features centre cutting geometry which allows limited plunge capability, but it is optimised for milling operations rather than primary drilling.

How does the TiCN coating affect performance?
The TiCN coating increases wear resistance and thermal stability, extending tool life and enabling machining of higher strength materials with better edge retention.

Is the Weldon shank compatible with standard toolholders?
Yes, the Weldon shank (TW) provides a secure clamping interface and is compatible with standard holders that accept a 12 mm shank with a drive flat.

What standard does the tool conform to and why is that relevant?
Conformity to DIN 844 ensures dimensional and geometric consistency with common tooling systems, simplifying replacement and inventory management.
