End mill D844 Type N (12 mm) — TECWERK, HSS‑Co8 with TiCN coating

An End mill D844 Type N designed as a long‑reach, centre‑cutting tool for milling steel, stainless steel and cast iron with a Weldon shank for secure clamping

• 63 mm effective cutting length
• TiCN coating for increased life
• Weldon shank for secure clamping
• Four flutes for efficient chip evacuation

High performance for demanding materials

The long‑reach design based on DIN 844 offers a balance of rigidity and accessibility for deeper pockets and step milling. The HSS‑Co8 substrate provides improved toughness compared with standard high‑speed steel, while the TiCN coating increases wear resistance and allows machining at higher structure stresses. Specified as a centre‑cutting tool, the geometry supports plunge starts and reliable axial engagement, making the cutter suitable for finishing and semi‑finishing where reproducible surface quality is required.

Precision clamping and repeatable results

A Weldon shank combined with a cylindrical shaft and drive flat secures the tool in standard holders and reduces slippage under load, supporting repeatable positioning in series production. The four flutes improve chip evacuation and maintain a steady cutting edge contact, which reduces chatter and helps preserve dimensional accuracy. With an overall length of 110 mm and an effective cutting length of 63 mm, the long variant is tuned for accessibility without compromising the control needed for tight tolerance work.

Practical application and material guidance

The tool is optimised for machining steel, INOX and cast iron, showing very good performance on those materials. The specification notes enhanced capabilities when the cutter is used with its coating: uncoated tools operate effectively up to approximately 800 N/mm², while the TiCN‑coated version extends service into the region of 1,200 N/mm², widening the range of suitable workpieces. Right‑hand cutting and the Z4 configuration balance chip removal and surface finish; this makes the tool appropriate for component finishing and shape milling where both productivity and surface integrity matter.

Readiness for integration in production

The tool’s long version and centre‑cutting capability simplify set‑up for multi‑operation sequences and reduce tool changes in small‑batch and jobbing environments. Packaging comes as single units to allow exact inventory control. For customers consolidating tool procurement, the cutter’s standard DIN reference and Weldon shank ensure compatibility with a wide range of existing toolholding systems, aiding swift integration into current machining processes.

FAQ

Which materials is this cutter best suited for? The TECWERK End mill D844 Type N is specified as very good for steel, INOX and cast iron, with conditional suitability for some non‑ferrous metals and special alloys.

What benefits does the TiCN coating provide? TiCN coating on the D844 improves wear resistance and enables higher operating stresses compared with the uncoated variant, extending tool life in demanding steel and inox applications.

Is this tool suitable for plunge cutting? Yes, the centre‑cutting geometry of the D844 Type N permits plunge starts and axial engagement for operations requiring direct entry into the material.

What clamping does the shank require? The Weldon shank with drive flat is intended for secure clamping in standard Weldon holders, providing reliable torque transmission for repeatable machining.

Can the tool be used in deep pocketing? The long configuration with a 63 mm effective length is designed to access deeper features while maintaining the stiffness needed for quality finishes; the SKU is 2000866404NW for ordering reference.
