TECWERK Shank End Mill DIN 844 Type HR — HSS‑Co5, Ø18 mm, Weldon shank

The TECWERK shank end mill DIN 844 Type HR is a short, four‑flute milling cutter designed for precision machining of steel and cast iron in workshop and industrial settings

• HSS‑Co5 high‑cobalt construction
• DIN 844 short 4‑flute design
• Centre‑cutting for plunge milling
• Weldon shank with drive flat

High cutting performance for demanding materials

The cutter’s HSS‑Co5 substrate provides increased red hardness and wear resistance compared with standard high‑speed steels, enabling sustained cutting in tougher applications. The DIN 844 short geometry with Ø18 mm nominal diameter and 42 mm cutting length offers a compact solution for interrupted cuts and operations where tool stability is critical. Its centre‑cutting geometry permits controlled plunging, while the right‑hand cutting orientation ensures predictable chip flow in most conventional setups. These features translate to consistent cycle times and fewer tool changes on the shop floor.

Secure clamping and stable runout for repeatable accuracy

The Weldon shank with drive flat ensures positive retention in setscrews and quick‑change holders, reducing the risk of micro‑slip under radial load. The short, robust profile minimises overhang and vibration, improving surface finish and dimensional repeatability in series production. Combined with the four‑flute design, this results in a balance between chip evacuation and rigidity, making the cutter suitable for slotting, peripheral milling and plunge operations where a compact toolholder arrangement is required.

Practical productivity and tool life considerations

A 45° protective chamfer on the tool reduces chipping at the cutter entry and helps to preserve the cutting edges during positioning. For uncoated tools, the geometry and material are optimised for workpieces with a tensile strength up to approx. 800 N/mm²; where a suitable coating is applied, the same basic cutter concept can handle materials up to around 1200 N/mm², extending service life in higher‑strength steels. The four‑cutting‑edge configuration supports moderate feed rates while maintaining a fine surface finish, reducing secondary operations and overall machining cost per part.

Typical applications and handling recommendations

This short 4‑flute end mill is particularly recommended for machining steel and cast iron, with conditional suitability for non‑ferrous metals depending on the specific alloy and machining parameters. Its centre‑cutting capability allows safe plunge starts; however, for deep slotting or extended overhangs, toolholders that maximise clamping length are advised. When selecting cutting data, align speeds and feeds with the HSS‑Co5 substrate’s strength—prioritise conservative entry conditions and increase feed progressively while monitoring surface finish and tool wear.

FAQ

Which materials are best machined with this cutter?
The TECWERK shank end mill DIN 844 Type HR is very well suited to steel and cast iron; non‑ferrous metals are conditionally suitable depending on alloy and cutting data.

Can the tool be used for plunging or ramping operations?
Yes, the centre‑cutting geometry of the DIN 844 Type HR allows controlled plunging and ramping, making it suitable for plunge milling tasks.

How is the cutter held in the machine spindle?
The cutter features a Weldon shank with a drive flat for secure clamping with setscrews or compatible toolholders, improving retention under heavy radial loads.

Is the tool supplied coated?
This entry refers to the uncoated HSS‑Co5 version; coating increases permissible tensile strength up to approx. 1200 N/mm², but the supplied tool is the uncoated variant per product data.

What is the product code for ordering and inquiries?
Refer to SKU 2000866502NW when enquiring about the TECWERK shank end mill DIN 844 Type HR to ensure accurate identification and supply.
