6mm Mini Cutter HSS-Co8 3-Flute Short Weldon, Centre Cutting, Right-Hand - TECWERK

Benefit from the short design, HSS‑Co8 composition and Weldon shank for rigid, repeatable slotting in demanding workshop applications; order the mini slot cutter directly via Metav Werkzeuge or consult our specialists for matching tool holders and feed recommendations.

Mini slot cutter Ø 6 mm, HSS‑Co8, Weldon shank, 3‑flute (TECWERK)

The Mini slot cutter Ø 6 mm HSS‑Co8 is a short, three‑flute cutter with centre cutting and a Weldon shank, designed for precise slotting and keyway work in steel and cast iron components.

• HSS‑Co8 material for high wear resistance
• 3‑flute centre cutting for accurate slotting
• Weldon shank, 6 mm for secure clamping

Rigidity and accuracy for small, precision slots

The short overall length (39 mm) combined with a cutting length of 3 mm gives the tool enhanced rigidity, reducing vibration and improving dimensional stability during slotting operations. The compact geometry is particularly advantageous when working in confined fixtures or where minimal overhang is required; the result is a cleaner surface finish and tighter tolerance control. This makes the cutter well suited for precision workshop and production tasks where consistent repeatability is essential.

Material choice that extends tool life

Constructed from HSS‑Co8 (cobalt high‑speed steel), the cutter offers improved hot‑hardness and edge stability compared with standard HSS. The three flutes balance chip evacuation and cutting edge strength, supporting efficient material removal in tougher steels up to approximately 800 N/mm². For users less familiar with metallurgical designations: HSS‑Co8 contains 8% cobalt, which helps the tool keep hardness at elevated temperatures and lengthens service life under intermittent or heavy cutting.

Secure clamping and centre‑cutting capability

The Weldon shank with drive flat provides a positive, slip‑resistant connection in set‑screw holders and collet systems designed for Weldon tools. As a centre‑cutting tool, the cutter can perform limited plunge operations as well as conventional peripheral slotting, enabling the creation of short blind slots without pre‑drilling in many setups. The right‑hand cutting direction suits standard CNC and manual milling arrangements and matches common spindle rotation conventions.

Practical suitability across common workshop materials

Application data indicates very good suitability for steel and cast iron, with conditional performance on stainless steels and some non‑ferrous metals. The short tool body and robust HSS‑Co8 composition are advantageous when machining cast components or medium‑strength steels; for delicate non‑ferrous work, feeds and speeds should be adapted to avoid built‑up edge. The cutter is aimed at machinists and toolroom professionals seeking a compact, versatile slotting solution rather than a long overhang or deep‑slot specialist.

FAQ

What materials is this cutter best suited for?
The TECWERK mini slot cutter is very well suited for steel and cast iron; it is conditionally appropriate for stainless steels and some non‑ferrous metals depending on cutting data.

Can the cutter be used for plunge cutting?
Yes, the tool is centre cutting, so limited plunge operations and short blind slots are possible without pre‑drilling in many applications.

What clamping system is required for safe use?
The cutter features a Weldon shank with drive flat, intended for secure clamping in set‑screw holders and compatible toolholders for Weldon shanks.

How does the HSS‑Co8 material benefit performance?
HSS‑Co8 provides increased hot‑hardness and edge life compared with standard HSS; this improves tool life during tougher cuts and intermittent heavy use.

Is the tool suitable for automated CNC production?
The cutter’s short design and three‑flute geometry support rigid, repeatable machining; specific feeds and speeds should be set according to machine capability and workpiece material.
