8mm Spigot Cutter HSS-Co8 3-Flute Long Cut, 40° Helix, 10mm Shank - TECWERK

Take advantage of the combination of durable HSS‑Co8 construction, a Weldon shank for secure clamping, and a geometry optimised for long‑chip aluminium to keep production running smoothly; order the cutter directly via Metav Werkzeuge or consult their specialists for machining recommendations.

TECWERK slot drill DIN 844 Type W, 8 mm — HSS‑Co8, 3‑flute, Weldon shank

The TECWERK slot drill DIN 844 Type W (8 mm) is a long, three‑flute, centre‑cut milling cutter designed for slotting and plunge operations in long‑chip aluminium and other non‑ferrous metals

• HSS‑Co8 construction for high wear resistance
• Three‑flute centre‑cut design for efficient chip control
• Weldon shank Ø10 mm for secure clamping
• Optimised for long‑chip aluminium and non‑ferrous metals

Dependable cutting performance for non‑ferrous production

The long three‑flute cutter is manufactured from HSS‑Co8, a cobalt‑alloyed high‑speed steel that combines hardness and thermal resistance for prolonged tool life under demanding conditions. Its centre cutting geometry allows controlled plunging and slotting without the need for a separate drill pre‑operation, reducing setup steps. Conformity with DIN 844 guarantees familiar dimensions and reliable repeatability in production environments, making the tool suitable for component runs where consistent performance is required.

Faster cycle times through optimised chip evacuation and helix geometry

A 40° helix angle and the three‑flute layout improve chip evacuation and reduce the risk of built‑up edge when machining long‑chip aluminium alloys. The free relief of 7.5 mm and a cutting length of 3 mm are balanced to support accurate slot formation while keeping cutting forces moderate; the result is smoother sidewalls and fewer interruptions for manual chip removal. Reduced chip packing and improved surface finish contribute directly to lower rework rates and higher effective throughput on CNC milling centres.

Secure clamping, compatible dimensions and easy handling

The cutter is supplied with a Weldon shank and a shaft diameter of 10 mm, enabling secure clamping in standard Weldon holders and collet chucks with drive‑flat contact. With an effective length of 44 mm and an overall length of 88 mm, the tool offers reach for deeper slots while maintaining rigidity to minimise chatter. Right‑hand cutting direction and the three cutting edges provide balanced cutting forces, making the tool well suited to automated production runs. Buyers benefit from Metav Werkzeuge’s supply reliability and product range when integrating this cutter into a broader tooling strategy.

FAQ

What materials is this cutter best suited for?
The TECWERK slot drill DIN 844 Type W is optimised for long‑chip aluminium and other non‑ferrous metals; its HSS‑Co8 composition and 40° helix improve chip formation and evacuation for these materials.

Can the tool be used for plunge operations?
Yes. The cutter features centre cutting geometry, enabling controlled plunging and slotting without a separate pilot drill.

Which shank size and clamping type are required?
A 10 mm Weldon shank with a drive flat is supplied, so secure clamping in Weldon holders or compatible chucks is recommended to prevent slippage.

Does the cutter meet standard specifications?
The tool is manufactured to DIN 844 standards and is suitable for integration into standard tooling setups on CNC milling machines.
