TECWERK HSS‑Co8 End Mill DIN 844 Type N — Ø16 mm, 4‑flute, Weldon shank

The TECWERK HSS‑Co8 end mill DIN 844 Type N is a long, four‑flute cutter designed for precise milling and plunge operations in steel and cast iron applications

• HSS‑Co8 high‑speed steel, 8% cobalt
• DIN 844 Type N, long 4‑flute design
• Weldon shank with drive flat for secure clamping
• Centre‑cut geometry permits plunge milling

Precision cutting for demanding components

Built from HSS‑Co8, the cutter combines toughness with red hardness for stable performance under load. The DIN 844 Type N geometry and 4‑flute layout deliver a balanced chip evacuation and a consistent cutting edge, which reduces vibration and improves surface finish. The centre‑cut feature enables controlled plunge capability, so internal pockets and interrupted cuts can be approached without extra tooling steps. This makes the tool especially suitable where dimensional accuracy and repeatable results are required.

Deep reach and secure clamping for confident machining

The long design with a 73 mm cutting length and a Ø16 mm diameter provides the reach necessary for deeper cavities while maintaining rigidity. The Weldon shank with drive flat ensures secure clamping in holders that accept Weldon‑style shanks, reducing the risk of slippage during high feed operations. Together, these features allow extended reach without a disproportionate loss of stability, supporting efficient one‑setup machining of deeper features.

Optimised performance across common workshop materials

Performance data indicate suitability up to 800 N/mm² with the uncoated tool and up to 1200 N/mm² when used with an appropriate coating, improving applicability in harder materials. The cutter is rated very good for steel and cast iron and conditionally suitable for non‑ferrous metals and stainless steels; this guides selection for mixed production environments and helps plan coating or tool changes to extend tool life. The robust HSS‑Co8 substrate resists chipping when machining interrupted cuts, contributing to predictable service life.

Integrating the cutter into process and procurement

As part of a practical tooling strategy, the long four‑flute design reduces the number of required tool changes for complex parts and simplifies inventory by covering both slotting and plunge tasks in many cases. Metav’s positioning as a precision partner supports straightforward sourcing: a wide product range and dependable stock handling mean shorter lead times and consistent quality selection. For technical queries on feeds, speeds or holder compatibility, consult the supplied specifications or our technical advisors to align the cutter with specific machine capabilities.

FAQ

What materials is the cutter best suited for?
The TECWERK HSS‑Co8 end mill (SKU 2000866386NW) is very well suited for steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on workpiece hardness and cutting parameters.

Can this cutter perform plunging operations?
Yes — the centre‑cut geometry permits plunge milling and controlled entry into pockets, making the tool suitable for interrupted cuts and internal features without pre‑drilling in many applications.

What shank and clamping arrangement is required?
The tool features a Weldon shank with a drive flat, requiring a Weldon‑style holder or clamping system that secures the shank across the flat for slip‑free machining.

How does coating affect capability?
With an appropriate coating the cutter’s capability increases from approximately 800 N/mm² (uncoated) to around 1200 N/mm² (coated), improving wear resistance and enabling work on harder materials.
