4mm Mini Slot Cutter HSS-Co8 3-Flute Long Centre Cutting 3mm Cut, 6mm Shank - TECWERK

Take advantage of the combination of a HSS‑Co8 cutting grade, a long three‑flute geometry and a secure Weldon shank to mill narrow slots and keyways with consistent chip control; order the tool directly via Metav Werkzeuge or consult the specialists for machining parameters.

Mini slot cutter Ø4 mm – HSS‑Co8, 3‑flute, long (Weldon) by TECWERK

Mini slot cutter Ø4 mm for precise slotting and keyway milling in low to medium strength metals, designed as a long three‑flute, centre‑cutting tool with a Weldon shank for secure clamping

• Long 3‑flute design for smooth chip evacuation
• HSS‑Co8 for elevated heat and wear resistance
• Weldon shank Ø6 mm for secure clamping
• Centre‑cutting with right‑hand spiral for slotting

Increased lifetime and consistent cutting performance

The HSS‑Co8 alloy provides enhanced hardness and thermal resistance compared with standard high‑speed steels, which translates into fewer tool changes and steadier cutting behaviour when machining mild and medium‑strength steels. The three flutes reduce chatter and distribute cutting forces more evenly, resulting in improved surface finish and longer tool life. For operations in cast iron the geometry is particularly effective, while non‑ferrous materials and stainless steels remain conditionally suitable depending on the chosen feeds and speeds.

Reliable clamping and vibration control for small tooling

A Weldon shank with a drive flat and a Ø6 mm shaft ensures the cutter is held without slippage in ER collets or direct Weldon holders, which is critical for miniature tools where run‑out amplifies. The long overall length (42 mm) combined with a 3 mm cutting length offers access to deeper or narrow slots without sacrificing rigidity when set up correctly. These features support steady chip evacuation and reduce rework caused by tool movement or poor seating.

Practical guidance for applications and setup

As a centre‑cutting, right‑hand cutting tool with a nominal Ø4 mm, this cutter is suitable for plunge and peripheral milling of narrow grooves, keyways and index features in components up to approximately 800 N/mm² tensile strength. The tool is very well suited for steel and cast iron applications; use conservative radial engagement and controlled axial passes for best results. For non‑ferrous alloys and stainless steel, adjust cutting speeds and increase coolant or lubrication to compensate for reduced thermal conductivity and chip‑forming behaviour.

FAQ

What materials can this cutter machine effectively?
The TECWERK mini slot cutter is very well suited for steel and cast iron, while non‑ferrous metals and stainless steel are conditionally suitable depending on machining parameters.

Is the tool suitable for plunge cuts?
Yes, the centre‑cutting geometry of the mini slot cutter allows controlled plunge cutting as well as peripheral milling operations.

What clamping options are recommended for this cutter?
Use a Weldon holder or a high‑precision collet with a secure clamping surface for the Ø6 mm shank to minimise run‑out and prevent slippage.

How many flutes does the cutter have and what are the benefits?
The cutter has three flutes; this offers improved chip removal, reduced vibration and a finer surface finish compared with two‑flute variants.
