18mm Solid Carbide End Mill DIN 844 NR Short 42mm Cutting Length HSS-Co5 TiCN Weldon - TECWERK

Take advantage of the combination of HSS‑Co5 construction, TiCN coating and a Weldon shank for secure clamping and extended tool life; this short, centre‑cut end mill delivers consistent performance in steel and cast iron and can be ordered directly via Metav Werkzeuge or discussed with our technical consultants.

End mill DIN 844 Type NR D 18 mm L 42 mm — HSS‑Co5, TiCN, Weldon shank (TECWERK)

The End mill DIN 844 Type NR D 18 mm L 42 mm HSS‑Co5 TiCN Weldon TW is a short, multi‑flute cutter designed for medium‑duty milling of steel and cast iron where a robust, centre‑cutting tool and reliable clamping are essential.

• HSS‑Co5 solid cobalt grade
• TiCN coating for wear resistance
• Weldon shank with drive flat
• Optimised for steel and cast iron
• Short, centre‑cut multi‑flute design

High performance for medium‑strength materials

The tool is built from HSS‑Co5, a cobalt‑alloyed high‑speed steel that provides the strength needed for demanding cutting tasks. Combined with the TiCN coating, the cutter sustains higher cutting speeds and improved wear resistance, which translates into longer service intervals and fewer tool changes. Designed to machine materials up to approximately 800 N/mm² with an uncoated geometry and up to 1000 N/mm² when the coating is used, the cutter offers a measurable performance envelope that aids production planning and reduces downtime.

Secure clamping and precise engagement

Featuring a Weldon shank with a drive flat, the end mill ensures reliable torque transmission and minimal slippage in the tool holder, which is particularly important during heavy interruptions or plunge cuts. The short, centre‑cut geometry and the DIN 844 Type NR profile allow for axial engagement and thermal stability, enabling confident slotting and shoulder milling. A 45° protective chamfer on the cutting edge reduces chipping at entry and helps preserve the tool’s cutting geometry during repetitive operations.

Versatile suitability and predictable results

The cutter is very well suited to steel and cast iron, with conditional suitability for non‑ferrous metals, special alloys and stainless steels. The multi‑flute configuration balances material removal rate and surface finish; it delivers efficient chip evacuation while maintaining dimensional control. For users integrating the tool into batch production or repair work, the defined cutting limits and material recommendations support predictable cycle times and consistent component quality.

Practical handling and workshop benefits

A cylindrical shank with a dedicated drive flat simplifies tool change procedures and reduces set‑up time, supporting smoother workflows on the shop floor. The right‑hand cutting direction and the relieved helical profile contribute to stable cutting forces and a controlled surface finish. For workshops seeking to consolidate suppliers while maintaining precision, this cutter offers compatibility with standard tool holders and straightforward inventory handling.

FAQ

What materials is the end mill best suited for?
The TECWERK End mill DIN 844 Type NR D 18 mm L 42 mm HSS‑Co5 TiCN Weldon TW is very well suited for steel and cast iron, with conditional suitability for non‑ferrous metals, stainless steels and special alloys.

Can the cutter be used for plunging operations?
Yes, the centre‑cutting geometry allows axial engagement, so the end mill can perform plunge cuts in appropriate setups while maintaining stability and tool life.

How does the TiCN coating affect performance?
The TiCN coating increases wear resistance and enables higher cutting speeds; with the coating applied, the cutter is rated for work in materials up to approximately 1000 N/mm², improving endurance and reducing tool changes.

What clamping system is required for reliable use?
A standard tool holder compatible with a Weldon shank and drive flat is required to ensure secure clamping and torque transmission during milling.
