20mm Milling Cutter HSS-Co5 TiCN Coating 52mm Effective Length DIN 844 - TECWERK

Choose the HSS‑Co5 substrate and TiCN coating for a durable, high‑performance cutter that combines toughness with extended wear resistance; the Weldon shank ensures secure clamping and fast changeovers. Order the tool directly via Metav Werkzeuge or ask our consultants if needed.

End mill DIN 844 Type HR, 20 mm — HSS‑Co5, TiCN coating, Weldon shank (TECWERK)

A 20 mm end mill Type HR designed for short, high‑performance milling of steel and cast iron with a secure Weldon shank for reliable clamping.

• HSS‑Co5 substrate for high toughness
• TiCN coating for extended tool life
• DIN 844 Type HR, four‑flute geometry
• Weldon shank with drive flat

Faster machining with consistent tool life

Built to DIN 844 standards, this end mill combines a HSS‑Co5 backbone with a TiCN surface finish to balance toughness and wear protection. The four‑flute geometry delivers stable cutting engagement and even chip evacuation during peripheral milling and finishing cycles. With an effective length of 52 mm, the cutter suits short‑reach operations where stiffness and accuracy matter; the centre‑cutting design allows axial plunging without special pilot tools, reducing setup time and boosting throughput.

Secure clamping and reliable repeatability

A Weldon shank with drive flat provides positive torque transfer and simple tool changes in collet chucks or holders with a Weldon clamp, lowering the risk of slippage under load. The short, robust profile and right‑hand cutting direction contribute to vibration dampening on standard milling machines, improving surface quality and extending service intervals. The tool’s relief geometry and fine cord profile give a predictable cutting feel and repeatable results across batch production.

Broad material suitability for workshop demands

The cutter is optimised for steel and cast iron, with the data indicating very good suitability for steel and very good suitability for cast iron. Non‑ferrous metals, special alloys and stainless steels are rated as conditionally suitable; select the coated variant for tougher alloys. Performance guidance in the specification notes machining limits of ~800 N/mm² with an uncoated tool and up to ~1200 N/mm² when coated, enabling informed decisions on tool choice relative to workpiece strength.

Practical handling and process recommendations

Short‑profile cutters like this one benefit from rigid setups and conservative overhang to exploit the HSS‑Co5 toughness. Use appropriate cutting parameters for the material class and consider coolant or lubricant strategies where heat or built‑up edge risk exists; the TiCN layer helps to reduce adhesive wear and improve surface finish. For assistance with feeds, speeds or holder selection, technical advice is available to ensure the cutter matches production requirements and machine capability.

FAQ

What makes this end mill suitable for steel machining?
The HSS‑Co5 substrate combined with the TiCN coating and four‑flute Type HR geometry provides toughness and wear resistance; TECWERK’s end mill to DIN 844 is optimised for steel and cast iron applications.

Can the cutter perform plunging operations?
Yes, the centre‑cutting design allows axial plunging without additional pilot tools, enabling direct entry in many milling setups.

Which clamping systems are compatible with the Weldon shank?
A Weldon clamp or collet chuck accepting a 20 mm Weldon shank is appropriate; the drive flat ensures secure torque transmission for the TECWERK end mill (SKU 2000866520NW).

Is the TiCN coating necessary for all materials?
TiCN improves wear resistance and is particularly beneficial for harder or abrasive materials; for softer steels and cast iron, the uncoated variant retains excellent toughness.

How does the tool geometry affect surface finish?
The short, four‑flute profile and fine cord relief reduce vibration and support consistent chip removal, which contributes to improved surface quality in finishing passes.
