Mini slot cutter Ø2.5 mm HSS‑Co8, Weldon shank, 3‑flute, short — TECWERK

A compact, short three‑flute mini slot cutter in HSS‑Co8 designed for precision slotting and plunge cutting in components up to approximately 800 N/mm².

• HSS‑Co8 for wear resistance
• Three‑flute design with centre cutting
• Weldon shank with 6 mm drive flat
• Short overall length ideal for confined setups

Accurate slotting for high‑strength components

The mini slot cutter Ø2.5 mm combines a HSS‑Co8 substrate with a centre‑cutting geometry to enable plunge operations and short, accurate slotting cycles. Designed for machining components with tensile strengths up to ~800 N/mm², the tool delivers repeatable groove profiles where rigidity and tool life matter. The three‑flute configuration balances chip evacuation and cutting edge engagement, helping to maintain dimensional stability during intricate groove work.

Rigid, compact geometry reduces deflection

A short overall length of 36 mm and a 6 mm shank translate to improved stiffness at the cutting edge, reducing deflection and vibration in confined set‑ups. The Weldon shank with drive flat secures the cutter in standard collets or chucking systems, providing positive torque transmission in small‑part fixtures. For operations where access is restricted, the compact design lowers the risk of chatter and increases first‑pass yield.

Efficient cutting action and predictable chip control

The three‑flute layout promotes consistent chip formation while offering a balance between feed capability and surface finish. Right‑hand cutting and centre‑cut capabilities allow for ramping or direct plunging without pre‑drilling, shortening cycle times on repetitive slotting tasks. The cobalt‑enriched high‑speed steel substrate improves red‑hardness and wear resistance, supporting longer tool life in interrupted cutting conditions common with slot entry.

Versatile workshop uses and material suitability

This short mini slot cutter is optimised for steel and cast iron (both rated very good), with conditional suitability for non‑ferrous metals and stainless steel when parameters are adapted. Typical applications include precision groove milling, keyway finishing, micro slotting in tool and die work, and tight‑tolerance features on small assemblies. Integration into CNC‑based micro‑machining or manual milling stations is straightforward thanks to its standard shank and Weldon clamping face.
