TECWERK Slot Milling Cutter DIN 844 Type W, Ø 16 mm, HSS‑Co8, Weldon shank (short, 3‑flute)

A TECWERK Slot Milling Cutter DIN 844 Type W designed for short, centre‑cutting slot milling in aluminium and other non‑ferrous metals

• HSS‑Co8 for high wear resistance
• Centre‑cutting three‑flute geometry
• Weldon shank with drive flat for secure holding
• Optimised 40° helix for long‑chip aluminium

Higher material removal rates for long‑chip non‑ferrous work

The tool’s HSS‑Co8 composition delivers increased red‑hardness and wear resistance, which supports sustained performance during continuous slotting of aluminium and other non‑ferrous metals. The 40° helix encourages predictable chip formation and evacuation when machining long‑chip alloys, reducing the risk of built‑up edge and improving surface quality. In practice, this means fewer tool changes and more consistent cycle times on production batches where aluminium alloys dominate.

Secure plunging and reliable slot starts with centre‑cutting geometry

A centre‑cutting design combined with 3 flutes enables safe plunging and rapid entry when creating bores or translating to axial slotting operations. The short overall length increases rigidity, reducing chatter and deflection in compact set‑ups or when clamping close to the holder. For shops handling interrupted cuts or frequent slot entry, the geometry offers a pragmatic balance between cutting efficiency and dimensional stability, aiding repeatable tolerance control.

Robust clamping and easy tool‑holder integration

The Weldon shank with drive flat provides a positive, repeatable grip in standard collet chucks and Weldon holders, helping to resist rotational slip under heavier axial loads. The tool’s Ø 16 mm shank matches the cutting diameter, simplifying holder selection and concentricity management. A 15 mm free cutting length is ground to provide clearance for slot depths common in fixture work while maintaining a compact, stiff tool overhang — an advantage for small machining centres and multitasking turning‑milling cells.

Practical guidance for workshop use and material suitability

Specified under DIN 844 Type W, the cutter is optimised for long‑chip aluminium and is rated very good for other non‑ferrous materials; this makes it especially suitable for fabrication of extruded parts, housings and heat‑sensitive components that require smooth chip flow. The three‑flute layout balances flute volume and core strength, facilitating higher feed per tooth without compromising surface finish. For applications outside non‑ferrous alloys, consultation on cutting parameters is recommended to ensure tool life and part quality.

FAQ

What materials is this cutter best suited to?
The TECWERK slot milling cutter is optimised for aluminium and other non‑ferrous metals; the HSS‑Co8 grade and 40° helix promote controlled chip formation for long‑chip alloys.

Can this tool be used for plunge cutting and slotting?
Yes. The centre‑cutting geometry and three‑flute design allow safe plunging and axial slotting with good stability for short‑length applications.

Which holder type is recommended for secure clamping?
A Weldon holder or a collet chuck with Weldon screw is recommended to use the Weldon shank drive flat effectively and to avoid slip during higher axial loads.

How does the short design affect machining accuracy?
The short configuration increases rigidity and reduces deflection, improving repeatability and surface finish in tight clamping scenarios and when minimal overhang is required.

Is the cutter compliant with an industry standard?
The tool conforms to DIN 844 Type W, ensuring interchangeability and predictable geometry for production planning and tool inventories.
