TECWERK End Mill DIN 844 Type HR, 18 mm, HSS‑Co5 — 4‑flute, 42 mm effective length, Weldon shank

TECWERK End Mill DIN 844 Type HR is a short, high‑performance HSS‑Co5 four‑flute cutter engineered for milling steels and castings in workshop and production environments.

• HSS‑Co5 for high wear resistance
• DIN 844 Type HR short design
• Four‑flute with 45° protective chamfer
• Weldon shank, 16 mm cylindrical shank

Consistent material removal with robust HSS‑Co5 construction

The HSS‑Co5 composition gives this tool elevated red‑hardness and wear resistance compared with conventional high‑speed steels, which results in extended life under intermittent or demanding cuts. The four‑flute geometry balances strength and chip evacuation for stable side milling and slotting operations. Designed to DIN 844 as a Type HR short cutter, the tool combines rigidity with a compact overhang, reducing deflection and improving surface finish when machining medium‑strength materials such as steel and castings. This makes the cutter a reliable choice for repetitive workshop tasks where process stability and predictable tool life are priorities.

Secure clamping and precise engagement for repeatable results

A Weldon shank with a 16 mm diameter provides positive drive and easy tool change in standard chucks and holders; the shank’s drive flat ensures the tool resists rotation under torque. The cutter’s Zentrumschnitt (centre cut) capability enables limited plunge work, while the 45° protective chamfer at the cutting edge reduces edge chipping during entry. With an effective cutting length of 42 mm and an overall length of 92 mm, the geometry is optimised for short‑reach face and peripheral milling, delivering consistent engagement and repeatability on production runs.

Application range and material suitability explained plainly

The tool is rated for machining materials up to approximately 800 N/mm² in uncoated form; data indicate potential extension to ~1200 N/mm² when used with a suitable coating. Practical suitability is: very good for steel, very good for castings and conditionally suitable for non‑ferrous alloys. The short, robust profile and the hinterschliffenes feines Kordelprofil (relieved fine rope profile) help to maintain cutting geometry under load, reducing burr formation and improving dimensional control on series parts. For customers assessing tool selection, this means fewer rejects and longer intervals between tool changes.

Handling, set‑up and operational benefits in the workshop

The cutter’s short design and balanced flute geometry help to reduce vibration and allow somewhat higher feeds than long overhang alternatives, improving cycle times in many standard milling setups. The four cutting edges provide multiple regrinds compared with two‑flute options, enhancing economy across the tool’s lifetime. The cylindrical shank with a drive flat ensures quick, reproducible clamping; using a proper Weldon clamping system keeps runout low and secures concentricity, which is essential for component consistency in batch production.

FAQ

What materials is this end mill best suited to machine?
The TECWERK end mill is very well suited for steel and castings, and conditionally suitable for non‑ferrous metals; performance is typically quoted up to about 800 N/mm² in uncoated form.

Can the Weldon shank be used in standard holders?
Yes, the Weldon shank (TW) with a 16 mm diameter on SKU 2000866502NW is compatible with standard Weldon holders and chucks that accept a drive flat for secure clamping.

Is the cutter capable of limited plunge operations?
The centre‑cut design allows limited plunging and entry cuts; the short Type HR geometry is primarily optimised for side and face milling with improved rigidity.

How does the short design benefit workshop productivity?
The compact overhang reduces deflection and vibration, allowing steadier cuts and often higher feed rates compared with longer cutters, which helps to shorten cycle times on repeat production tasks.

What edge protection and profile features improve tool life?
The 45° protective chamfer and the relieved fine rope profile reduce edge chipping and support stable chip formation, contributing to predictable wear behaviour and longer usable life for the cutter.
