TECWERK D844 Type N end mill – 5 mm, HSS‑Co8, TiCN coating

A TECWERK D844 Type N end mill designed for long-reach precision milling in steels, stainless steel and cast parts, featuring a Weldon shank and centre-cutting geometry for secure clamping and plunge capability.

• HSS-Co8 high-speed steel for durability
• TiCN coating for extended tool life
• Four-flute design for efficient chip removal
• Weldon shank with drive flat for secure clamping

Precision and material compatibility for reliable results

The cutter is produced to DIN 844 and made from HSS‑Co8, offering a robust substrate that balances toughness and wear resistance for intermittent and continuous milling. The TiCN coating reduces friction and extends tool life, allowing the cutter to handle higher surface speeds than an uncoated variant. With a nominal diameter of 5 mm and an effective cutting length of 24 mm, the geometry supports accurate profile generation and dimensional stability in series production. Centre‑cutting capability permits limited plunge operations, so the tool can be used where occasional axial entry is required without additional pre‑drilling.

Increased productivity through geometry and coating

The four‑flute configuration improves contact ratio and delivers finer surface finishes while maintaining chip control in slotting and side milling. Coated operation raises the usable material hardness threshold: the tool processes steels up to approximately 800 N/mm² with an uncoated tool and reaches up to around 1200 N/mm² when used with the TiCN finish, enabling confident machining of tougher workpieces. The overall length of 68 mm provides extended reach for deep pockets and features, reducing the need for tool changes or special extensions and supporting continuous production runs with fewer interruptions.

Secure clamping and consistent machining quality

A Weldon shank with drive flat and 6 mm shank diameter ensures positive engagement in straight‑shank holders and chucks, minimising slippage and axial movement under load. Right‑hand cutting direction aligns with standard machining strategies for predictable chip flow and tool life. The long‑series design and centre‑cutting geometry combine to offer flexibility across tasks: the cutter is very well suited to stainless steel and cast iron, conditionally suitable for non‑ferrous metals and special alloys, and offers robust behaviour in demanding shop environments. The tool’s construction reduces vibration and runout, supporting repeatable tolerances and fewer rejected parts in production.

FAQ

Is this cutter suitable for stainless steel?
Yes. The TECWERK D844 Type N end mill is rated as very well suited for stainless steel, owing to its HSS‑Co8 substrate and TiCN coating.

Can the tool be used for plunge milling?
The centre‑cutting geometry allows for limited axial entry; the cutter is designed for occasional plunge operations as well as conventional side milling.

What clamping system is required for secure use?
A standard straight holder that accepts a 6 mm Weldon shank with drive flat is appropriate to prevent slippage and ensure stable clamping during machining.

Which materials should be avoided or handled with caution?
Non‑ferrous metals and special alloys are conditionally suitable; assess feed and speed carefully and consider application‑specific testing before series machining.
