TECWERK Slot Drill DIN 844 Type W – 16 mm HSS‑Co8, Weldon shank, 3 flutes (short)

TECWERK Slot Drill DIN 844 Type W is a short, centre‑cutting three‑flute cutter engineered for slotting long‑chipping aluminium and other non‑ferrous metals with a 40° helix angle

• HSS‑Co8 for increased heat resistance
• Centre‑cutting for plunge and slot milling
• Weldon 16 mm shank with drive flat
• Optimised for aluminium and non‑ferrous metals

High‑performance design for efficient slotting

The short, three‑flute design combines rigidity and chip evacuation to maintain consistent cutting conditions in long‑chipping materials. Made from HSS‑Co8, the tool tolerates higher thermal loads and retains edge stability during sustained cutting, which reduces rework and machine downtime. The 40° helix promotes smooth chip formation in aluminium alloys and similar materials, while the centre‑cutting geometry permits controlled plunging operations without a pilot hole. These characteristics support faster cycle times and predictable surface quality in series production and workshop tasks.

Robust connection and secure clamping for precision work

A Weldon shank with drive flat ensures positive torque transfer and reduces the risk of slippage under load, improving repeatability when slotting or plunge milling. The solid cylindrical shank at 16 mm diameter fits standard toolholders and collets used in milling centres and manual mills, enabling easy tool change and a compact setup. Right‑hand cutting and the short overall length minimise overhang, which helps to preserve concentricity and minimise deflection during deep or contained slotting operations.

Material suitability and application guidance

This cutter is specifically prepared for long‑chipping aluminium and other non‑ferrous metals; the material selection and flute geometry favour continuous chips and a clean finish. The tool’s features make it well suited for tasks such as slotting, step milling and light plunge cuts in brass, copper and similar alloys. For mixed material jobs or hardened steels, alternative grades would be advisable; for more complex applications, Metav consultants can provide matching tool recommendations and machining parameters.

Practical benefits for workshop and production environments

With an effective length engineered to balance reach and stiffness, and a relief length designed to avoid rubbing, this tool reduces the likelihood of chatter and improves tool life in everyday use. The three‑flute configuration provides a compromise between chipspace and cutting edge strength, meaning fewer tool changes and a steady production flow. Combined with Metav’s logistics and quality control from Emmerich, the cutter contributes to dependable supply and consistent outcomes on the shop floor.

FAQ

What materials is this cutter best suited for?
The TECWERK slot drill (DIN 844 Type W) is designed for long‑chipping aluminium and other non‑ferrous metals; its HSS‑Co8 composition and 40° helix facilitate smooth chip formation in these alloys.

Can the cutter be used for plunge cutting?
Yes. The centre‑cutting geometry allows controlled plunge milling without a pre‑drilled pilot, suitable for short plunges and slot entry operations when using the correct feeds and speeds.

What shank retention is recommended for safe operation?
A secure clamping system compatible with a 16 mm Weldon shank and drive flat is recommended to prevent slippage and ensure torque transmission during heavier slotting cuts.

How does the 40° helix affect machining performance?
The 40° helix promotes continuous chip formation and improved surface finish in aluminium and similar materials, while aiding chip evacuation to reduce heat build‑up and tool wear.
