TECWERK End Mill DIN 844 Typ NR, 18 mm – HSS‑Co5, TiCN, Weldon shank

The TECWERK End Mill DIN 844 Typ NR is a short, multi‑tooth, right‑hand end mill designed for productive milling of steel and cast iron in workshop and production environments.

• HSS‑Co5 core for prolonged tool life
• TiCN coating for enhanced wear resistance
• Weldon shank with drive flat for secure clamping
• 4 flutes and 42 mm cutting length for stable machining

Durable substrate and coating for longer tool life

The combination of a HSS‑Co5 substrate and a TiCN surface treatment provides a balance of toughness and wear resistance that suits demanding workshop tasks. Cobalt‑alloyed high‑speed steel increases red‑hardness and fracture resistance, while the titanium carbonitride coating reduces abrasive wear and improves performance when machining harder steels. This means fewer tool changes and steadier cycle times when working on components with medium tensile strength; the tool can manage materials up to around 800 N/mm² with an uncoated edge and up to 1,000 N/mm² when the coating is applied, offering a clear efficiency advantage in mixed production runs.

Secure clamping and geometry that reduces vibration

A Weldon shank with a 16 mm dimension and drive flat gives a robust, slip‑free interface with standard toolholders, improving concentricity under load. The cutter’s short, compact design and 4 flutes combine to provide stable cutting behaviour and controlled chip formation in interrupted or continuous cuts. The tool is centre‑cutting, permitting limited plunge operations, and features a back‑relieved core profile and a 45° protective chamfer that together enhance rigidity and reduce chatter—important for achieving consistent surface finish and dimensional accuracy on small‑batch or repair work.

Application focus and practical machining guidance

This short, multi‑edge cutter is optimised for machining steel and cast iron (very good suitability), with conditional applicability to non‑ferrous metals, stainless steels and special alloys. The tool’s 18 mm diameter, 42 mm effective cutting length and 92 mm overall length make it suitable for milling pockets, slots and finishing passes where rigidity and repeatability matter. For unfamiliar materials or critical components, pairing the cutter with conservative axial depths and moderate feeds is advised until process windows are established; technical consultation is available for optimising speeds and feeds for specific machines and workflows.

FAQ

What materials is this end mill best suited to?
The TECWERK End Mill DIN 844 Typ NR is very well suited to steel and cast iron; non‑ferrous metals, stainless steels and special alloys are conditionally suitable depending on cutting parameters and part requirements.

Does the tool allow plunging operations?
Yes, the cutter is centre‑cutting, which permits limited plunge milling and ensures flexible operation for short pocket entries and face milling.

How does the TiCN coating affect performance?
The TiCN coating increases abrasive wear resistance and allows the HSS‑Co5 substrate to machine harder steels up to approximately 1,000 N/mm² under appropriate conditions, extending tool life and reducing changeovers.

Is the Weldon shank compatible with standard toolholders?
The Weldon shank with a 16 mm diameter and drive flat ensures secure clamping in standard Weldon holders, improving concentricity and minimising slippage during heavy cuts.

Can this cutter be used for finishing and roughing?
The short, multi‑tooth geometry and 4 flutes make the cutter suitable for finishing passes and light roughing operations where rigidity and surface quality are priorities; heavier roughing may require a dedicated roughing geometry.
