Schaftfräser DIN 844 Typ NR D.20mm Einsatz-L.52mm HSS-Co5 Weldon TW — 20 mm HSS‑Co5 short multi‑flute end mill with Weldon shank

Schaftfräser DIN 844 Typ NR D.20mm Einsatz-L.52mm HSS-Co5 Weldon TW designed for short, high‑precision milling tasks in steels and cast iron where rigidity and repeatability matter

• HSS‑Co5 material for improved heat resistance
• DIN 844 Type NR short, multi‑flute design
• Weldon shank with drive flat for secure clamping
• Suited for steel and cast iron up to 800 N/mm²

Faster, more consistent cuts in medium‑strength steels

The HSS‑Co5 composition increases red hardness and wear resistance compared with standard high‑speed steel, which translates into longer in‑service life under elevated temperatures. With a cutting length of 4 mm and a 52 mm effective length, this short multi‑flute cutter reduces tool overhang and deflection, producing repeatable dimensional accuracy in series operations. For workshops machining components up to approximately 800 N/mm² with an uncoated tool, this specification balances cost and performance while allowing predictable tool change intervals and stable cycle times.

Robust clamping and stable toolholding for repeatable precision

A Weldon shank with a drive flat provides positive, secure clamping in standard toolholders, limiting slippage during heavy cuts and supporting consistent concentricity. The cylindrical shank with drive flat design and compact overall length mean reduced vibration and improved surface finish without specialised holders. Together with the four‑cut configuration and right‑hand cutting direction, the cutter offers stable chip removal and reliable engagement, which is particularly beneficial for short batches where setup time must be minimised.

Accurate plunging and clean finishes for complex operations

Equipped with a centre cut and a slightly relieved profile, the cutter supports limited plunging and precise entry into material while maintaining a clean finish on the flank. The 45° protective chamfer helps to resist edge chipping at the cutting zone and promotes consistent corner quality when machining slots or shoulders. As an uncoated tool, it performs very well in steels and cast iron; coated variants can extend capability up to around 1,000 N/mm², but the current tool is optimised for common workshop alloys where economy and tool life are both priorities.

Suitable materials and practical workshop benefits

The geometry and material pairing make this cutter very well suited to steel and cast iron machining, while non‑ferrous metals are accommodated under specific conditions. The short, multi‑flute layout minimises chatter on rigid setups and helps achieve fine surface quality with fewer passes. Conforming to DIN 844 ensures compatibility with industry expectations for dimensions and performance, simplifying tool selection for procurement and production planning and reducing the number of specialised cutters required across the shop floor.

FAQ

Is this cutter suitable for plunge milling?
The Schaftfräser DIN 844 Typ NR D.20mm features a centre cut that permits limited plunging; for sustained plunging operations, specialised plunging end mills are recommended.

What materials can be machined with this HSS‑Co5 tool?
TECWERK's end mill is very well suited to steel and cast iron and conditionally suitable for non‑ferrous metals; its HSS‑Co5 composition improves heat resistance during medium‑strength steel machining.

Can the cutter be used in coated form for harder steels?
The current uncoated tool is optimised up to ≈800 N/mm²; with an appropriate coating, similar geometries can extend capability to around 1,000 N/mm².

What toolholder is required for the Weldon shank?
A standard Weldon‑capable toolholder that accepts a 20 mm shank with a drive flat is suitable for secure clamping and repeatable concentricity with this SKU 2000866434NW.

Does the cutter comply with recognised standards?
Yes, the geometry and dimensions conform to DIN 844, ensuring predictable interchangeability and documented dimensional tolerance.
