TECWERK HSS‑Co5 end mill DIN 844 Type NR — 20 mm, TiCN, Weldon shank

A TECWERK HSS‑Co5 end mill engineered as a short, multi‑flute DIN 844 Type NR cutter for productive milling of steels and cast iron in industrial and workshop environments

• HSS‑Co5 material for high wear resistance
• TiCN coating for enhanced hardness and life
• Weldon shank with drive flat for secure clamping

High‑performance cutting from HSS‑Co5 and TiCN

The combination of HSS‑Co5 high‑speed steel and a TiCN (titanium carbonitride) coating provides a balanced mix of toughness and surface hardness. This results in longer tool life under intermittent loads and improved resistance to abrasive wear. For shops processing medium‑strength steels, the coated cutter extends the usable tool life and helps maintain dimensional stability over longer production runs, reducing tool changes and improving throughput.

Secure clamping and standardised design for reliable setups

Built to DIN 844 with a Weldon shank and drive flat, the cutter offers a robust interface with standard toolholders and milling arbors. The 20 mm shank diameter and cylindrical shank profile ensure a stable connection for heavy cuts and repeated operations, while the short design supports rigid setups. These features translate into consistent surface finish and reduced vibration during machining, which preserves both the tool and the workpiece geometry.

Geometry tailored for effective material removal and finish

This multi‑flute tool features 4 flutes, a centre‑cutting geometry and a 45° protective chamfer, delivering a controlled entry and good axial penetration where required. The relieved core profile reduces cutting forces and improves chip flow, particularly in cast iron and medium‑strength steels. As a result, the cutter achieves efficient material removal rates with a good balance between surface quality and tool life, making it suitable for series production and precision tasks alike.

Application guidance and practical benefits for production

Designed for machining materials up to approximately 800 N/mm² with uncoated tooling and up to 1000 N/mm² with coated tooling, this end mill is very well suited for steel and cast iron and conditionally suitable for non‑ferrous metals, special alloys and stainless steels. Regular inspection of the cutting edges and appropriate coolant application will preserve the TiCN layer and extend service intervals. For reliable selection, reference SKU 2000866450NW when specifying the cutter for procurement or tool management systems.

FAQ

Is this cutter suitable for plunging operations?
The cutter has a centre‑cutting geometry, so the TECWERK end mill (SKU 2000866450NW) permits limited axial entry; full‑depth plunging should be evaluated against setup rigidity and material.

What advantage does the TiCN coating offer?
The TiCN coating on the TECWERK end mill increases surface hardness and wear resistance, extending life especially when machining tougher steels.

Will the Weldon shank work with standard holders?
Yes, the Weldon shank with drive flat is compatible with standard clamping systems and secures the cutter against rotation in typical milling holders.

Which materials are best machined with this tool?
This cutter is optimised for steel and cast iron, with conditional suitability for non‑ferrous metals, special alloys and stainless steel when parameters are adjusted.

How many flutes does the tool have and why does that matter?
The cutter features 4 flutes, offering a compromise between chip evacuation and finish; this supports efficient finishing passes and stable cutting in the intended material classes.
