TECWERK End Mill DIN 844 Type HR Ø8 mm — HSS‑Co5, TiCN‑coated, Weldon shank

The TECWERK end mill is a long, four‑flute cutter designed for demanding general machining, offering a TiCN coating for wear resistance and a Weldon shank for secure clamping.

• HSS‑Co5 core with TiCN coating
• Four‑flute geometry for high material removal
• 44 mm effective cutting length
• Weldon shank with drive flat, 10 mm shank

Consistent cutting performance through material and coating

The combination of HSS‑Co5 substrate and a TiCN (titanium carbonitride) coating provides a robust mix of toughness and surface hardness. The cobalt alloyed high‑speed steel increases hot hardness and resistance to plastic deformation, while the TiCN layer reduces adhesion and abrasive wear on the rake face. This results in longer tool life and more predictable tool change intervals when machining medium‑to‑high strength steels. The tool is manufactured to DIN 844, the standard for long‑length end mills, which supports stable clamping and controlled overhang in milling setups.

Designed geometry for efficient chip evacuation and surface finish

A four‑flute configuration with a finely relieved helical profile gives a good balance between chip removal and surface integrity. The tool is centre‑cutting, enabling axial plunging where required, and features a 45° protection chamfer to strengthen the cutting edge in interrupted cuts. The moderate flute count supports higher feed rates in finishing and semi‑finishing passes, while the refined profile reduces vibration and produces consistent surface quality on both machined steel and cast components.

Practical benefits at the machine and in process planning

The Weldon shank with drive flat ensures secure retention in collets and holders, reducing the risk of slippage under higher torque or heavier axial loads. With an effective cutting length of 44 mm and total length of 88 mm, the tool suits operations where reach is needed without excessive overhang. The right‑hand cutting direction and fine channel geometry make it suitable for conventional milling strategies commonly used in production shops; tool life and cycle time improvements can be achieved by pairing the cutter with appropriate coolant and modest reductions in depth of cut when first trialling a new material.

Application range and material suitability explained

The cutter is rated for work on a wide range of materials: very good for steels and cast iron, conditional for non‑ferrous metals and special alloys, and limited for stainless variants depending on heat treatment and alloying. The specification indicates suitability up to approximately 1200 N/mm² tensile strength, which covers most engineering steels and many cast materials. For demanding stainless or heat‑resistant alloys, trial cuts are recommended to verify feed and speed settings; the TiCN coating will help but the HSS‑Co substrate has thermal limits compared with carbide solutions.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited to machining steels and cast iron and is conditionally suitable for non‑ferrous metals and special alloys depending on individual alloy properties.

Can the cutter be used for plunging operations?
Yes, the tool is centre‑cutting, which permits axial plunging; appropriate feed and pecking strategies are recommended for deep plunges.

What advantages does the TiCN coating provide?
The TiCN coating increases surface hardness and reduces built‑up edge, which improves wear resistance and extends the service life of the HSS‑Co5 tool.

How does the Weldon shank benefit production use?
The Weldon shank with drive flat secures the cutter against rotation in the holder, minimising slippage during heavy cuts and ensuring repeatable positioning in production runs.
