Shank cutter DIN 844 Type NR — HSS‑Co5 short multi‑flute end mill, 8 mm × 25 mm (TECWERK)

The shank cutter DIN 844 Type NR is a short, multi‑flute HSS‑Co5 end mill designed for stable milling and plunge operations in steel and cast components in general workshop and industrial use.

• HSS‑Co5 construction for high wear resistance
• Short multi‑flute design for stable milling
• Weldon shank with drive flat for secure clamping
• Centre‑cut profile for reliable plunge milling

Efficient cutting performance for production work

The combination of HSS‑Co5 (high‑speed steel with approximately 5% cobalt) and a short, multi‑flute geometry provides elevated wear resistance and increased rigidity compared with longer cutters. This results in a steady material removal rate and reduced chatter during transverse milling. The tool’s trimmed profile and honed flute margins improve edge strength, so the cutter maintains a consistent surface finish over longer cycles and reduces the frequency of tool changes.

Secure clamping and dependable plunge ability

A Weldon shank with drive flat ensures positive seating in holder systems and prevents rotation under heavy loads, while the centre‑cut tip enables controlled plunge milling and entry into material without pilot holes. The cylindrical shank design with a drive face simplifies clamping in common toolholders and fosters repeatable concentricity, making the tool well suited for operations where secure fixation and precise axial engagement are essential.

Clear application limits and material suitability

The geometry and substrate make the cutter particularly effective on steel and cast iron, where the cutting edges withstand elevated temperatures and stresses. Non‑ferrous metals are conditionally suitable with care on feeds and speeds. For uncoated variants the practical upper strength limit is around 800 N/mm², rising to about 1000 N/mm² when using an appropriate coating on the tool; these figures indicate the cutter’s capability window and assist in selecting speeds and feeds for reliable tool life.

Workshop integration and handling benefits

Short overall length increases stiffness and reduces deflection, which aids dimensional control and surface quality on small features and pockets. Conformance to DIN 844 ensures interchangeability with existing toolholder setups and simplifies inventory management. The right‑hand cutting orientation and relief‑ground flute core reduce burr formation and support consistent chip evacuation in through‑slot and finishing passes, helping to keep production rhythms predictable.

FAQ

Which materials is this cutter best suited for?
The cutter is optimised for steel and cast iron, where the HSS‑Co5 substrate provides very good wear resistance and edge stability.

Can the tool be used for plunge milling and drilling into the workpiece?
Yes, the centre‑cut geometry enables controlled plunge milling and axial entry without a pilot when selected feeds and speeds are observed.

What clamping system is recommended for secure seating?
Use a holder compatible with Weldon shanks (drive flat) or a suitable Weldon toolholder to ensure positive torque transmission and repeatable concentricity.

Are non‑ferrous materials suitable for this end mill?
Non‑ferrous metals are conditionally suitable; machining softer alloys may require adjustments to feed rate and spindle speed to avoid built‑up edge.

What is the SKU for ordering and reference?
The product is listed under SKU 2000866465NW for TECWERK short HSS‑Co5 end mills.
