Slot drill DIN 844 Type W, 14 mm — HSS‑Co8, 3‑flute by TECWERK

The Slot drill DIN 844 Type W is a long, centre‑cutting slotting tool engineered for precision milling in aluminium and other non‑ferrous metals.

• HSS‑Co8 for improved heat resistance
• Three flutes for efficient chip evacuation
• Centre‑cutting for controlled plunging
• Weldon shank with drive flat for secure clamping

Fast, accurate slotting with optimised geometry

The long, three‑flute design delivers a balance of material removal rate and surface finish that suits batch and single‑part production. The HSS‑Co8 composition increases red‑hardness and wear resistance, which extends tool life under higher cutting temperatures; this leads to fewer tool changes and higher uptime. The 40° helix promotes consistent chip formation, reducing recutting and improving process stability, while the centre‑cutting feature allows safe, controlled plunging into the workpiece.

Secure holding and vibration‑reduced running

A 12 mm cylindrical shank with a Weldon drive flat ensures rigid clamping in holders designed for a Weldon interface, reducing slip and runout during deep slotting. The relief grind dimension (11.5 mm) minimises friction along the tool body where clearance is required, helping to preserve cutting geometry and reduce chatter. These features combine to provide predictable tool behaviour and repeatable slot tolerances in series production.

Ideal for long‑chipping aluminium and non‑ferrous materials

Designed specifically for long‑chipping materials, the flute and edge preparation deliver efficient evacuation in aluminium and similar alloys. The cutter’s geometry prevents chip packing and promotes continuous chip flow, which lowers the risk of surface damage. For applications requiring clean edges and consistent slot width in non‑ferrous components, this tool offers reliable performance with reduced rework.

Workshop integration and practical benefits

Conforming to DIN 844 as a Type W slot drill, the tool is compatible with standard toolholders and machining practices, simplifying stock management and tool selection. The right‑hand cutting orientation matches typical milling setups, and the long version allows deeper slotting without step‑over operations. With few variables to adjust, the cutter integrates smoothly into existing processes, supporting efficient production planning and reduced setup time.

FAQ

What materials is this slot drill suitable for?
The slot drill DIN 844 Type W is very well suited for aluminium and other non‑ferrous metals; the HSS‑Co8 grade and flute geometry promote long‑chip evacuation in these materials.

Can this cutter be plunged directly into the workpiece?
Yes, the centre‑cutting design of the TECWERK slot drill allows controlled plunging as well as conventional milling, enabling flexibility in slotting operations.

What shank size and clamping style does the tool require?
The cutter features a 12 mm cylindrical shank with a Weldon drive flat for secure clamping in holders designed for Weldon shanks.

How many flutes does the tool have and what advantage do they offer?
The tool has three flutes; this configuration balances chip evacuation and cutting edge strength for efficient slotting in long‑chipping materials.
