Slot drill DIN 844 Type W, 6 mm — HSS‑Co8, 3‑flute, Weldon shank (TECWERK)

A slot drill DIN 844 Type W (6 mm) designed for precise slotting and plunge cutting in long‑chip aluminium and non‑ferrous metals, featuring a Weldon shank and centre‑cut capability.

• HSS‑Co8 grade for extended tool life
• Three‑flute centre‑cut geometry
• Weldon shank with drive flat
• 40° helix for long‑chip evacuation
• Optimised for aluminium and non‑ferrous

Durable cobalt alloy for consistent performance

The use of HSS‑Co8 (cobalt‑alloy high‑speed steel) gives the cutter improved hot‑hardness and wear resistance compared with standard HSS, supporting higher cutting speeds and longer tool life when machining demanding materials. The three‑flute arrangement balances chip evacuation and cutting edge stability, reducing the need for frequent tool changes and improving process uptime. This combination translates into a measurable efficiency gain for serial slotting tasks where consistency and repeatability matter.

Secure clamping and centre‑cut geometry for versatile machining

A Weldon shank with drive flat provides abrasion‑resistant contact and reliable torque transfer in toolholders and chucks, reducing slippage during interrupted cuts. The centre‑cut design allows controlled plunge‑cutting and slotting without pre‑drilling, so the cutter can be used for through slots and pocket starts with confidence. The tool is right‑hand cutting and the centre‑cut geometry helps maintain positional accuracy during vertical entries, making it suitable for workshop setups that require repeatable plunge operations.

Geometry engineered for long‑chip aluminium and NE‑metals

With a pronounced 40° helix, the flute geometry promotes the formation and evacuation of long chips typical of aluminium and other non‑ferrous metals, reducing chip packing and re‑cutting. The tool’s relief and flute form are optimised for soft to medium‑hard non‑ferrous alloys, ensuring a clean surface finish and minimised built‑up edge. As a result, machining cycles run smoother, coolant usage can be controlled more effectively, and downtimes due to chip‑related issues are reduced.

Practical dimensions for workshop compatibility

The cutter is supplied in a 6 mm diameter with an overall length of 68 mm and an effective flute length of 30 mm, offering reach for deeper slots while keeping deflection low. The short cutting length of 3 mm is suitable for narrow slot operations and fine plunge depths, while the 6 mm shank diameter fits standard collets and Weldon holders. Conforming to DIN 844 Type W ensures straightforward integration into established tooling systems and simplifies tool replacement strategies across multiple workstations.

FAQ

Is this cutter suitable for aluminium slotting?
The TECWERK slot drill DIN 844 Type W (SKU 2000866300NW) is optimised for long‑chip aluminium and other non‑ferrous metals, offering a 40° helix and three‑flute geometry that promote reliable chip evacuation.

Can the cutter be used for plunge‑cutting and pocket starts?
Yes. The centre‑cut geometry enables plunge entries, allowing the cutter to start slots or pockets without pre‑drilling when using appropriate feeds and clamping.

What clamping system is required for safe operation?
A Weldon holder or compatible chuck that accommodates a 6 mm shank with drive flat is recommended to ensure secure torque transfer and prevent slippage during interrupted cuts.

Does the cutter comply with industry standards for interchangeability?
The tool conforms to DIN 844 Type W, which supports interchangeability and consistent performance across standardised tooling systems.

For which workshop applications is this long version most suitable?
The long configuration and 30 mm effective flute length make it suitable for deeper slotting tasks in small to medium components, particularly where aluminium and non‑ferrous alloys are processed.
