TECWERK HSS‑Co5 TiCN End Mill DIN 844 Type HR – Ø20 mm, Weldon shank

The TECWERK HSS‑Co5 TiCN end mill DIN 844 Type HR is a long, four‑flute, centre‑cutting milling cutter engineered for heavy machining of steel and cast iron in workshop and CNC environments

• HSS‑Co5 with TiCN coating
• Four‑flute, centre‑cutting geometry
• Weldon shank with drive flat
• Suitable up to ≈1200 N/mm²

Consistent performance for demanding materials

Built from HSS‑Co5, this long‑reach cutter combines hardness and toughness to withstand interrupted cuts and higher thermal loads common in steel and cast‑iron machining. The four‑flute layout increases material removal rate while maintaining a superior surface finish compared with two‑flute alternatives; flank wear is reduced thanks to the even load distribution. For applications that require predictable tool life and fewer tool changes, the long effective cutting length of 89 mm supports deep slotting and extended reach without compromising rigidity.

Coating and wear behaviour that extend uptime

The TiCN (titanium carbonitride) coating lowers friction at the cutting edge and improves resistance to abrasive wear, which translates into longer in‑service life and better edge retention. In practice this means fewer tool swaps during batch work and steadier cycle times on medium‑ to high‑strength steels. Material suitability is clear: very well suited for steel and cast iron, while non‑ferrous metals, special alloys and stainless steel (inox) are only conditionally suitable—select cutting parameters accordingly to avoid built‑up edge and premature wear.

Geometry and shank design for secure machining

A centre‑cutting geometry enables plunge milling and helical entry without pre‑drilling, expanding the tool’s versatility. The tool features a 45° protective chamfer and a relief‑ground fine cord profile that support chip formation and reduce rubbing on the margin. The cylindrical Weldon shank with drive flat ensures positive torque transfer in standard holders and collets, giving a secure connection for higher feeds. Conformance to DIN 844, Type HR means standardised dimensions and straightforward integration into existing tool inventories.

Practical integration and recommended applications

This cutter is optimised for heavy‑duty milling of bars, flanges and cast parts where tensile strength approaches 1200 N/mm²; typical tasks include roughing and semi‑finishing in small series and workshop production. The right‑hand cutting direction and four flutes favour higher feed per tooth and lower cycle times on CNC machines. For optimal results, pair the tool with stable clamping, appropriate coolant or MQL strategies, and machining parameters that reflect the workpiece material class to avoid overload and to keep tool life predictable.

FAQ

What materials is this end mill primarily intended for?
The TECWERK end mill (SKU 2000866560NW) is very well suited to steel and cast iron and is rated for materials up to approximately 1200 N/mm²; non‑ferrous metals, special alloys and stainless steel are conditionally suitable.

Can this cutter be used for plunge milling or helical entry?
Yes — the centre‑cutting geometry allows plunge operations and helical entry, enabling the tool to perform both axial and peripheral milling tasks.

What advantages does the TiCN coating offer?
The TiCN coating on the HSS‑Co5 body increases surface hardness, reduces friction at the cutting edge and improves wear resistance under abrasive or elevated‑temperature conditions.

How is the tool secured in the spindle or holder?
The tool has a cylindrical shank with a Weldon drive flat, providing secure torque transmission and reliable clamping in common holders and collet systems.

Which standard and tool type applies to this cutter?
The cutter complies with DIN 844, Type HR and is manufactured from HSS‑Co5 as specified on the product label (SKU 2000866560NW).
