3mm Mini Slot Cutter HSS-Co8 3-Flute Short With Weldon Shank, Right-Hand Cutting - TECWERK

Benefit from the combination of robust HSS‑Co8 material, a three‑flute centre‑cut geometry and a secure Weldon shank for reliable, precise slotting in steels and cast iron; order directly via Metav Werkzeuge or consult our technical team for application advice.

Mini slotting end mill, 3 mm (HSS‑Co8) — short, 3‑flute, Weldon shank (TECWERK)

The mini slotting end mill, 3 mm (HSS‑Co8) is a short, three‑flute, centre‑cut slotting tool designed for precise slotting and light plunge operations in steels and cast iron up to approx. 800 N/mm².

• HSS‑Co8 for enhanced heat resistance
• Three‑flute, centre‑cut geometry for plunge cuts
• Weldon shank with flat for secure clamping
• Suited for steel and cast iron up to 800 N/mm²

Accurate small‑slot machining with high thermal stability

The short three‑flute design combines compact geometry with stiff cutting behaviour, enabling accurate slot creation in confined workspaces. Manufactured from HSS‑Co8, the tool offers improved red hardness and wear resistance compared with standard high‑speed steel, which reduces tool wear during intermittent cutting. The centre‑cut geometry permits controlled plunge entries, so slotting and light plunging can be carried out without pre‑drilling in many applications. The compact 3 mm diameter is ideal for narrow grooves, keyways and fine detailing where machine access and rigidity are limiting factors.

Secure clamping for repeatable results and reduced vibration

A Weldon shank with drive flat ensures positive engagement in set‑screw toolholders and minimises slippage under torque. The short cutter length contributes to reduced overhang, improving concentricity and lowering the risk of chatter. The right‑hand cutting direction is compatible with standard milling setups and provides a predictable cutting force direction for fixture design. With a 6 mm shank diameter, the cutter fits common collets and Weldon holders found in most toolrooms and machining centres, supporting fast changeover and consistent runout performance.

Application guidance and material suitability

The tool is optimised for structural and medium‑strength steels, with very good suitability for steel and cast iron up to approx. 800 N/mm². Performance on stainless steel (INOX) and non‑ferrous metals is conditional and depends on cutting parameters and coolant strategy; in such cases, reduced feed and careful speed selection are advised. The short, centre‑cut configuration also aids in finishing passes where surface quality matters. For customers requiring a compact cutting solution for repetitive small‑slot work, this cutter delivers a balance of stiffness, cutting life and handling convenience.

FAQ

What materials is this cutter best suited for?
The mini slotting end mill by TECWERK is very well suited for steel and cast iron applications and performs up to approx. 800 N/mm²; suitability for stainless steel and some non‑ferrous metals is conditional and depends on cutting settings.

Can the cutter perform plunge cuts?
Yes, the centre‑cut design allows controlled plunge entries, so light plunging and slotting without pre‑drilling are feasible with correct feeds and speeds.

Which shank holders are compatible with this tool?
The tool features a Weldon shank with flat, making it compatible with set‑screw Weldon holders and appropriate collet chucks that accept a 6 mm shank.

Is this tool suitable for finishing passes?
The short, stiff profile of the TECWERK cutter lends itself to finishing passes in narrow slots, delivering improved surface quality when combined with appropriate machining parameters.

How does the HSS‑Co8 material affect tool life?
The HSS‑Co8 composition increases red hardness and wear resistance compared with standard HSS, extending tool life under elevated temperatures and intermittent cutting typical of slotting operations.
