TECWERK short three‑flute slot drill, HSS‑Co8, D 5 mm (Weldon shank) — DIN 844

The TECWERK short three‑flute slot drill is a compact DIN 844 groove cutter designed for milling precise slots and grooves in long‑chip non‑ferrous materials.

• HSS‑Co8 high‑cobalt steel for durability
• Three‑flute, centre‑cutting geometry
• Weldon shank with 6 mm diameter
• Optimised for long‑chip aluminium and non‑ferrous metals

Precise geometry for reliable slot formation

The short three‑flute cutter is manufactured to DIN 844 standards and constructed from HSS‑Co8, a high‑cobalt high‑speed steel that increases resistance to heat and wear. The three‑flute layout balances chipspace with cutting edge count to produce a steady feed and reduced vibration, while the centre‑cutting design permits clean entry into material without pre‑drilling. These characteristics result in consistent groove profiles and longer service intervals compared with standard high‑speed cutters.

Controlled chip evacuation and surface quality

With a 40° helix angle, the tool channels long chips away from the cutting zone, which is particularly beneficial when working with aluminium and other non‑ferrous metals that generate continuous swarf. The short overall length increases stiffness at the cutting edge, lowering the risk of chatter and improving surface finish. As a consequence, the cutter supports efficient finishing passes and predictable machining outcomes, making it suitable for both small series production and precise workshop tasks.

Secure clamping and practical workshop handling

The Weldon shank with a 6 mm diameter ensures secure clamping in standard holders and quick‑change systems, maintaining concentricity during demanding operations. Being right‑hand cutting and compact in design, the tool is well suited to plunge cuts and tight‑space machining where rigidity is essential. The combination of centre‑cutting capability and a robust shank simplifies setup and reduces the need for secondary operations, supporting smooth workflow and dependable repeatability.
