16mm Cylinder End Mill HSS-Co8 TiCN Coating 73mm Cutting Length DIN 844 - TECWERK

Benefit from the combination of HSS‑Co8 heat resistance, a TiCN-coated cutting edge and a long 73 mm cutting reach for efficient deep milling; order the TECWERK end mill directly via Metav Werkzeuge or ask our consultants if technical advice is required.

TECWERK End Mill D844 Type N – 16 mm, HSS‑Co8, TiCN, 4‑flute, Weldon shank

The TECWERK End Mill D844 Type N is a long, centre‑cut, four‑flute HSS‑Co8 cutter designed for productive milling of steels and stainless steels in workshop and industrial environments.

• High‑performance HSS‑Co8 substrate with TiCN coating
• Centre‑cut geometry for safe plunging operations
• Weldon shank with drive flat for secure clamping
• Long 73 mm cutting length for deep pocketing

Consistent high‑speed performance and wear resistance

The long four‑flute cutter combines a HSS‑Co8 substrate with a TiCN surface layer to deliver improved heat resistance and abrasion protection compared with unalloyed high‑speed steels. HSS‑Co8 contains cobalt to stabilise the microstructure at elevated temperatures, which means the tool can sustain higher cutting temperatures and maintain hardness during prolonged passes. The TiCN coating reduces friction and the risk of built‑up edge, so tool life is extended and less frequent tool changes are required, contributing to steady production flows.

Secure clamping and reliable plunge milling

A Weldon style shank with a drive flat provides mechanical locking for high‑torque operations; this is especially important for long‑reach cutters where axial and radial forces are greater. The tool’s centre‑cutting geometry allows vertical entry into material without pre‑drilling, while the four flutes balance chip removal and surface finish. For deep pockets or stepped features the 73 mm cutting length and 123 mm overall length facilitate access without compromising stability, and the right‑hand cutting direction aligns with standard milling setups.

Application scope and process benefits

Designed to the requirements of DIN 844 Type N, the tool is oriented towards machining components from a broad range of materials. With an uncoated tool the practical limit is around 800 N/mm² tensile strength, while the TiCN coating extends suitability up to approximately 1200 N/mm², making the cutter appropriate for many steels and stainless steels encountered in production and repair work. The combination of long reach, centre cutting and enhanced wear protection reduces cycle interruptions and supports higher material removal rates, yielding quantifiable efficiency gains on repeat operations.

Material suitability and workshop integration

Material compatibility is a core advantage: very good suitability for steel and stainless steel, very good for cast materials, and conditional suitability for non‑ferrous metals and special alloys. The Weldon shank integrates with standard toolholders and the DIN reference ensures interchangeability across setups. Labelling as a long, four‑flute, centre‑cut end mill signals its role in medium‑duty to heavy‑duty milling tasks where reach, repeatability and a secure clamping interface are decisive.

FAQ

What materials is this cutter best suited to machine?
The TECWERK end mill is very well suited to steel and stainless steel and is suitable for cast materials; non‑ferrous metals and special alloys are conditionally suitable according to process parameters.

Is the cutter suitable for plunge cutting?
Yes, the centre‑cutting geometry allows plunging operations without prior drilling and is combined with a TiCN coating for reduced built‑up edge during entry.

How is the tool secured in the spindle?
The tool uses a Weldon shank with a drive flat to permit secure clamping and reliable torque transmission in standard toolholders.

What production advantages does the TiCN coating provide?
The TiCN coating on the HSS‑Co8 substrate reduces friction and improves wear resistance, extending useful tool life and enabling higher cutting stresses than uncoated variants.

Which standard does the tool conform to?
The cutter is produced to DIN 844 Type N, providing a recognised specification for long, centre‑cut end mills.
