End mill DIN 844 Type NR, Ø18 mm, 42 mm cutting length – TECWERK HSS‑Co5, Weldon shank

The End mill DIN 844 Type NR Ø18 mm, 42 mm cutting length HSS‑Co5 Weldon TW is a short, multi‑flute carbide‑enhanced high‑speed steel cutter designed for precision face and slot milling in steel and cast iron applications

• HSS‑Co5 high‑cobalt construction
• Short multi‑flute design with centre cutting
• Weldon shank with drive flat for secure clamping
• Very good suitability for steel and cast iron

High productivity through material and geometry optimisation

The combination of HSS‑Co5 material and a multi‑flute, short design delivers elevated cutting stability and consistent chip evacuation, reducing cycle times in medium‑duty milling. The cutter’s centre cutting geometry allows plunge operations and short slotting without secondary tooling, while the 45° chamfer protects the cutting edges during tool entry. For production environments this translates into fewer tool changes and predictable throughput — crucial where efficiency and repeatability are measured in batch output.

Reliable performance across common engineering materials

Engineered for machining tasks up to the stated material strengths, the tool shows very good suitability for steel and cast iron, and conditional suitability for non‑ferrous alloys. With an effective cutting length of 42 mm and a solid Ø18 mm diameter, the geometry supports stable cuts in components up to moderate cross sections. The specification notes a higher allowable application limit for coated variants; when a coated tool is used, material strength limits increase, enabling tougher or higher‑alloy steels to be addressed without compromising surface finish or tool life.

Secure mounting and handling for workshop integration

The Weldon shank with drive flat ensures positive torque transmission and minimises slippage in robust clamping systems, supporting higher feed rates where machine rigidity permits. A relieved helix profile and rear‑relief flute design reduce cutting forces and help maintain a consistent surface quality, lowering the need for rework. The cutter is right‑hand cutting and conforms to DIN 844 dimensional expectations, which facilitates tool‑holder compatibility and simplifies inventory management in mixed fleets.

Practical implications for procurement and maintenance

Choosing this cutter supports cost‑efficient tooling strategies: the short, multi‑flute configuration balances tool life with lower spindle loads, while the Weldon shank simplifies replacement and reduces downtime during tool changes. For workshops aiming to centralise supplies, the standardised shank and nominal sizes make the tool an easy addition to a consolidated tooling stock, allowing predictable reordering and reduced administrative complexity.

FAQ

What materials is this end mill best suited to?
The end mill is specified as very good for steel and very good for cast iron, with conditional suitability for non‑ferrous metals; coatings can extend allowable application to harder steels.

Can the cutter be used for plunging operations?
Yes, the centre‑cutting geometry allows plunge cuts and short slotting; the tool’s short, multi‑flute design supports controlled entry without pre‑drilling.

How is the shank secured in the tool holder?
The Weldon shank with drive flat provides positive torque transmission and secure clamping in suitable tool holders, reducing slippage under load.
