Slot drill DIN 844 Type W, Ø 18 mm — HSS‑Co8, 3‑flute, Weldon shank (TECWERK)

The slot drill DIN 844 Type W is a short, three‑flute, centre‑cut cutter engineered for precision slotting and plunge operations in long‑chipping aluminium and non‑ferrous metals

*HSS‑Co8 for extended tool life
*Three‑flute design with centre cut
*Weldon shank, 16 mm shaft diameter
*Very good for non‑ferrous metals

High performance for consistent aluminium slotting

Built from HSS‑Co8 (cobalt high‑speed steel), this short DIN 844 Type W cutter combines wear resistance with toughness to withstand the demands of repetitive slot milling. The three‑flute geometry improves stability and chip evacuation compared with two‑flute alternatives, reducing built‑up edge when machining long‑chipping aluminium. The presence of a centre cut enables controlled plunge cuts without pre‑drilling, so set‑ups are simpler and cycle times are reduced. These characteristics translate into fewer tool changes and steadier process windows on shop floors working with non‑ferrous alloys.

Secure clamping and plunge capability for accurate results

The tool features a Weldon shank with a shaft Ø 16 mm, providing a positive drive and robust clamping for higher torque applications. With a total length of 92 mm and an effective length of 42 mm, the cutter balances reach and stiffness for slotting tasks where rigidity matters. The 40° helix angle contributes to smooth cutting forces and a good surface finish, while the right‑hand cutting orientation matches standard spindle rotation. These mechanical details ensure the cutter holds concentricity and reduces vibration, which benefits repeatable accuracy in production environments.

Workshop practicality and process reliability

Designed as a short variant with a relief length of 15 mm, the tool minimises rubbing and friction at the shank‑workpiece interface, improving heat dissipation during through‑cut and plunge operations. The three cutting edges share load across the tool, extending edge life and supporting stable feeds. Marked to the DIN family for dimensional and performance consistency, the cutter is supplied in a single‑piece packaging unit for straightforward inventory management. For workshops aiming to streamline tooling choices, this cutter represents a focused solution for milling slots and grooves in aluminium and other non‑ferrous materials with predictable, industrial‑grade results.
