End mill DIN 844 Type N, 4 mm, HSS‑Co8, Weldon shank — TECWERK

A End mill DIN 844 Type N 4 mm HSS‑Co8 Weldon shank designed for precision milling and short‑run plunging in steel and cast iron applications

• HSS‑Co8 for improved heat resistance
• DIN 844 Type N four‑flute geometry
• Weldon shank with drive flat for secure clamping
• Centre‑cutting short design for axial plunging

Better cutting performance through material and geometry

The HSS‑Co8 substrate combines high‑speed steel with approximately 8% cobalt, increasing red hardness and resistance to thermal softening. This results in more consistent cutting at elevated temperatures and extended tool life compared with plain HSS. The cutter is rated for machining materials up to 800 N/mm² with an uncoated tool and up to 1000 N/mm² when a coating is applied, which supports more aggressive feeds and higher cutting speeds where applicable. Suitability is highest for steel and cast iron, while non‑ferrous metals and stainless steels are conditionally acceptable depending on cutting parameters.

Secure clamping and compact design for precise operations

A Weldon shank with drive flat ensures positive clamping in standard toolholders, reducing the risk of slippage under higher torque. The 4 flutes provide a balanced compromise between chip evacuation and surface finish, while the centre‑cutting short design enables safe axial plunging for pocketing and blind‑hole entry without pre‑drilling. Compliance with DIN 844 Type N geometry assures predictable engagement angles and chip formation, minimising vibration in short‑reach setups. The compact 4 mm diameter is ideal for fine detail work and confined machining zones.

Practical benefits for workshop and production use

The short, robust construction reduces tool change time and supports efficient small‑batch production where tool accessibility matters. The four‑edge configuration and cobalt‑enhanced grade contribute to stable cutting conditions and fewer rejected parts, which translates directly into improved efficiency on the shop floor. For facilities seeking to standardise tooling, this cutter integrates with common milling holders and suits tasks from finishing to moderate roughing within its material limits. Clear technical specifications and conformity to industry standards make it straightforward to plan process parameters and spare‑tool inventory.

FAQ

Which materials are best processed with this end mill?
The TECWERK end mill DIN 844 Type N (SKU 2000866324NW) is very well suited for steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on speed, feed and tool coating.

Is the cutter suitable for axial plunging and pocket entry?
Yes. The short, centre‑cutting design allows axial plunging for pocketing and entry operations without a separate pre‑drill when used within recommended parameters.

What clamping method is required for reliable operation?
Use a toolholder compatible with a Weldon shank and drive flat to ensure secure clamping and to prevent rotation under load.

What cutting direction and flute count does the cutter have?
The tool is a right‑hand cut with 4 flutes, offering a balanced surface finish and chip control for the stated material range.

Can coated tooling extend the application range?
Applying an appropriate coating increases performance; the tool’s data indicate achievable machining up to 1000 N/mm² with a coated version compared with 800 N/mm² uncoated.
