End Mill DIN 844 NR, 18 mm (HSS‑Co5) — short multi‑flute, Weldon shank (TECWERK)

The End Mill DIN 844 NR is a short, multi‑flute solid carbide substitute in HSS‑Co5 form designed for tough milling tasks in steel and cast components with a robust Weldon shank for secure clamping.

DIN 844 short multi‑flute design
HSS‑Co5 grade for high toughness
Weldon shank with drive flat
Suitable for steel and cast up to ~800 N/mm²

High‑precision cutting where cycle time matters

Engineered to the DIN 844 standard, this short multi‑flute cutter delivers consistent chip evacuation and stable engagement at moderate depths. The high‑toughness HSS‑Co5 construction combines wear resistance and impact strength to reduce breakage risk in interrupted cuts. With an 18 mm diameter and 4 flutes, the geometry balances material removal rate and surface finish, making the cutter particularly suited for parts requiring precision without excessive machine load. The centre‑cutting design allows plunge starts where necessary, while the relief‑ground core profile improves stability under radial loading, helping to keep cycle times predictable.

Faster setups and dependable clamping for series work

A Weldon shank with drive flat provides a secure interface with common toolholders, lowering the risk of slippage during heavy engagement and reducing rework caused by micro‑movement. The cutter’s compact overall length and 42 mm effective length simplify tool‑offset programming and reduce the need for long overhangs, which in turn lowers chatter and improves tool life. These features support repeatable setups across batches and make the tool a practical choice for short to medium production runs where consistent clamping and process reliability matter.

Clear guidance on materials and cutting limits

The tool is optimised for machining ferrous materials: steel is very well suited and cast materials are handled effectively thanks to the alloyed high‑speed steel substrate. As supplied, the cutter is uncoated and rated for materials up to 800 N/mm²; if an application demands higher cutting speeds or harder workpieces, a coated variant of the same geometry can be specified to extend use up to approximately 1000 N/mm². Non‑ferrous metals are conditionally suitable, but feed and speed adjustments are recommended to avoid built‑up edge.

Practical durability and workshop ergonomics

With a short multi‑flute form and a protective 45° chamfer, the design minimises edge chipping during handling and in unstable cutting conditions. The combination of HSS‑Co5 material and the relief‑ground core ensures acceptable regrinding life in workshop practice, supporting refurbishment rather than disposal where production economics allow. The tool’s dimensions—18 mm diameter and 16 mm shank—match common collet and Weldon fixtures, easing tool inventory management and enhancing interchangeability across machines.

FAQ

What materials is the end mill best suited for?
The TECWERK end mill (End Mill DIN 844 NR, SKU 2000866432NW) is very well suited for steel and cast materials and is conditionally suitable for some non‑ferrous metals; adjust feeds and speeds accordingly.

Can this cutter be used for plunge milling?
Yes, the centre‑cutting geometry allows plunge starts, so axial entry and limited plunging operations are feasible with this short multi‑flute design.

Is the tool supplied with a coating?
The supplied cutter is uncoated; the HSS‑Co5 substrate is rated for materials up to approximately 800 N/mm² in its uncoated form, while a coated equivalent can extend capabilities to around 1000 N/mm².

What clamping system is required for secure use?
The Weldon TW shank with drive flat is designed for compatible Weldon holders or suitable collet adaptors to ensure secure clamping and to prevent rotation under load.

Is the cutter suitable for regrinding and maintenance?
The HSS‑Co5 alloy and relief‑ground core profile support workshop regrinding for certain wear patterns, extending practical tool life where refurbishment is economical.
