End mill DIN 844 Type NR, Ø16 mm, HSS‑Co5 – TECWERK

The End mill DIN 844 Type NR, Ø16 mm is a short, multi‑cutting HSS‑Co5 cutter designed for milling steel and cast iron in workshop and industrial settings.

• HSS‑Co5 high‑cobalt material
• Short multi‑flute design with centre cut
• Weldon shank with drive flat
• Machining: steel and cast iron up to ~800 N/mm²

Consistent chip control and robust cutting geometry

The cutter combines a short multi‑flute body with a centre cut and a 45° chamfer to ensure steady engagement in milling operations. The HSS‑Co5 grade provides improved hot‑hardness and wear resistance compared with standard high‑speed steels, which translates into more consistent performance under load. The relieved core profile reduces stress at the cutting edge and helps maintain form when machining interrupted surfaces, while the right‑hand cutting orientation supports conventional spindle setups. These technical choices result in reliable chip evacuation and a stable cutting process for repetitive production tasks.

Material range and application limits explained

Designed primarily for ferrous work, the tool is very well suited for steel and cast iron, with conditional use on non‑ferrous materials. With an uncoated tool, effective machining is possible up to approximately 800 N/mm²; when a suitable coating is applied, the tool concept can be pushed towards 1,000 N/mm², offering extended applicability for tougher steels. The specification suits workshops that require a balance between cost and capability: the geometry supports plunge milling due to the centre cut, while the multi‑flute arrangement improves surface finish in continuous cuts. Non‑ferrous materials may require adjusted feeds and speeds to avoid built‑up edge.

Secure clamping and straightforward handling on the machine

The Weldon shank with drive flat provides a positive drive for torque transmission and reduces the risk of slippage in the holder, particularly in heavy feed scenarios. The short overall length reduces overhang, limiting vibration and improving run‑out stability for finer surface quality. The cylindrical shank with a drive surface is compatible with standard toolholders that accept Weldon flats, enabling quick changeovers and predictable repeatability in series production. Together, these features favour efficient setup and stable cutting, contributing to lower scrap rates and less rework.

FAQ

What materials is this cutter best suited for?
The TECWERK end mill (End mill DIN 844 Type NR, Ø16 mm) is very well suited for steel and cast iron, with conditional use on non‑ferrous metals depending on feed and speed.

Can this tool be used for plunge milling?
Yes, the centre cut and short multi‑flute geometry of the end mill support plunge milling operations and controlled entry into the workpiece.

What does HSS‑Co5 mean for workshop performance?
HSS‑Co5 denotes a high‑speed steel with approximately 5% cobalt, offering better hot‑hardness and wear resistance for longer life under high thermal load compared with standard HSS.

Is the Weldon shank compatible with standard holders?
The Weldon shank with a drive flat is compatible with standard Weldon‑style collet holders and provides secure torque transmission for demanding milling tasks.

Which DIN standard does this cutter comply with?
The cutter conforms to DIN 844 (Type NR), which specifies the geometry and tolerances for this style of end mill.
