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

The End mill DIN 844 Type NR, 18 mm is a short, centre‑cutting multi‑flute cutter designed for general workshop and light industrial milling of ferrous and cast materials

• HSS‑Co5 high‑cobalt tool steel
• DIN 844 short multi‑flute design
• Weldon shank with drive flat
• Centre‑cutting, right‑hand flutes

Precise cutting and material resilience for demanding tasks

Made from HSS‑Co5, this short multi‑flute cutter delivers a balance of toughness and hot‑hardness that suits interrupted cuts and moderate feed rates. The 4 flutes combine chip evacuation with surface finish, reducing vibration compared with fewer‑tooth cutters. Compliance with DIN 844 denotes a standardised short‑type profile that supports rigidity where axial space is limited; the result is consistent dimensional accuracy and extended tool life when used within the stated material limits.

Rigid connection and tool geometry that improve accuracy

A Weldon shank with drive flat ensures secure clamping in standard holders and reduces slippage under torque, while the 16 mm shank diameter and 92 mm overall length maintain concentricity in most machine spindles. The 42 mm effective length and short cutter body increase stiffness; combined with the 45° protective chamfer and a backed‑off cord profile, this geometry reduces cutter tip damage and improves stability in slotting and peripheral passes. Centre‑cutting geometry permits controlled axial engagement for plunge work.

Application range and machining guidance for best results

The tool is very well suited to machining steel and cast iron, and is conditionally suitable for non‑ferrous metals. For uncoated cutters the practical limit is around 800 N/mm² material tensile strength; with appropriate coatings that limit may rise to about 1,000 N/mm². The right‑hand cutting direction and centre‑cutting tip allow plunge milling and conventional slotting; for high removal rates, adopt conservative axial depths and moderate speeds to retain tool life. Use appropriate coolant or lubricant where material adhesion or heat build‑up is a concern to maintain surface quality and tool integrity.

FAQ

Which materials are best machined with this end mill?
The TECWERK end mill is very well suited to steel and cast iron; non‑ferrous metals are conditionally suitable depending on feed and speed.

Can the cutter be plunged axially for pocketing?
Yes, the centre‑cutting geometry allows controlled axial plunging for pocketing and spot drilling operations.

What are the shank and diameter dimensions to check for holder compatibility?
The tool has an 18 mm diameter and a 16 mm shank; the overall length is 92 mm with an effective cutting length of 42 mm (SKU 2000866432NW).

Is a coating applied to improve performance?
This specific item is supplied uncoated; with suitable coatings the recommended material strength range increases to around 1,000 N/mm².

How does the Weldon shank benefit milling operations?
The Weldon shank with drive flat secures the cutter in the holder, reducing rotational slip and improving repeatability under load.
