Mini slot cutter Ø 3 mm HSS‑Co8, Weldon, 3 flutes, long – TECWERK

The Mini slot cutter Ø 3 mm HSS‑Co8 is a long, three‑flute cutter designed for precision slotting and groove milling in medium‑strength steels and cast iron

• HSS‑Co8 high‑cobalt construction
• 3‑flute geometry for smooth chips
• Weldon shank with drive flat
• Long version for deeper slotting

Durable alloy for consistent production results

The HSS‑Co8 composition provides a robust balance of hardness and toughness, offering improved resistance to heat and wear compared with standard high‑speed steels. This results in fewer tool changes and a steadier process in repetitive machining tasks, which supports higher throughput and predictable tolerances. For workshops aiming to reduce downtime, the alloy foundation is an economic choice that maintains edge life under intermittent and continuous engagement.

Geometry that controls chips and permits plunge operations

The cutter’s 3‑flute design promotes controlled chip formation and evacuation, producing a clean slot surface with reduced risk of built‑up edge. The integrated centre cut capability allows plunge cutting and short axial entry, expanding application options beyond conventional peripheral milling. With a cutting length of 3 mm and a nominal diameter of 3 mm, the tool is engineered for small, precise grooves where repeatable results and minimal burrs are required. The right‑hand cutting orientation supports standard machining setups.

Secure clamping and stable torque transmission

Equipped with a Weldon shank and a drive flat, the cutter provides reliable axial and torsional support when used in set‑screw holders or compatible tool holders. The shank diameter 6 mm offers straightforward integration into common collets and holders, helping to reduce run‑out and chatter. Stable clamping translates into improved surface finish and dimensional accuracy for narrow slots, while the long shank length enhances accessibility for deeper or recessed features.

Practical applications and material suitability

This mini slot cutter is specified for machining materials with low to medium strength up to approximately 800 N/mm², showing very good performance in steel and cast iron and conditional suitability for non‑ferrous alloys and stainless steels. Typical uses include fine slotting, keyway milling, short groove production and repair work in toolrooms and precision workshops. Selecting the cutter for compatible substrates will maximise tool life and component quality, making it a dependable option for small‑part production and maintenance tasks.

FAQ

Is the cutter suitable for plunge cutting?
Yes. The mini slot cutter has a centre‑cut design that permits plunge entry; the Mini slot cutter Ø 3 mm HSS‑Co8 from TECWERK supports short axial plunges for slot starts.

What materials does the tool perform best in?
The cutter is optimised for steel and cast iron, with very good performance up to approximately 800 N/mm²; performance in non‑ferrous alloys and inox is conditional and depends on the specific grade and cutting parameters.

Which clamping systems are compatible with the Weldon shank?
Set‑screw holders and collet systems that accept a 6 mm shank are suitable; the Weldon drive flat improves axial and torsional retention for secure cutting.

Can the tool be used for fine keyways and micro slots?
Yes. The Ø 3 mm diameter and 3‑flute geometry make it well suited for fine slotting, keyways and precision groove milling in small components.
