5mm Mini Slot Cutter HSS-Co8 3-Flute Long 3mm Cutting Length Right-Hand Weldon Shank 6mm - TECWERK

Take advantage of the combination of robust HSS‑Co8 material, a Weldon shank for secure clamping and a compact 5 mm cutting diameter for reliable slotting in steel and cast iron — order the tool directly via Metav Werkzeuge or ask the consultants for process recommendations.

Mini slot milling cutter 5 mm, HSS‑Co8, Weldon shank (TECWERK)

The mini slot milling cutter 5 mm is a long, centre‑cutting, three‑flute tool designed for precision slotting and keyway work in components made from medium‑strength steels and cast iron.

• HSS‑Co8 for enhanced heat resistance
• Three cutting edges for smooth chip removal
• Weldon shank with drive flat for secure clamping
• Suitable for steel and cast iron up to ~800 N/mm²

Accurate slotting and plunge capability for reliable component fits

The long three‑flute geometry delivers consistent chip evacuation and a fine surface finish while maintaining tool stability during entry. Manufactured from HSS‑Co8, the cutter offers improved hot hardness and toughness compared with standard high‑speed steel, which supports repeatable results under interrupted cuts. The centre‑cutting design enables plunge cuts and accurate slot starts without pre‑drilling, reducing setup time and ensuring precise fits for keys and slots in assemblies. This combination of geometry and material provides a practical balance between tool life and machining performance for demanding workshop tasks.

Process security with secure clamping and compact dimensions

A Weldon shank with a drive flat ensures reliable axial and radial retention in standard collet chucks or Weldon holders, reducing slippage during higher feed operations. With a 5 mm cutting diameter and a 6 mm shank diameter, the tool suits compact toolchains and small machining centres while preserving rigidity. The long version, with a total length of 44 mm and a cutting length of 3 mm, allows access to deeper slots without compromising clamping stability. Right‑hand cutting combined with three cutting edges supports even load distribution, which translates into steady performance and fewer rework cycles when machining mild to medium‑strength steels.

Material suitability and recommended applications

The cutter is optimised for ferrous applications: very well suited for steel and cast iron, and conditionally suitable for non‑ferrous alloys and stainless grades where lower cutting forces and appropriate feeds are applied. The solid‑cobalt alloy base increases resistance to work hardening and thermal softening, making it appropriate for intermittent cutting in workshop environments. Use this tool for precision keyways, narrow slots and internal grooving where compact geometry and plunge capability reduce cycle complexity and improve repeatability across small batches.

FAQ

What materials is this cutter best suited for?
The TECWERK mini slot milling cutter (SKU 2000866052NW) is very well suited for steel and cast iron, with conditional suitability for non‑ferrous metals and some stainless grades when appropriate feeds are used.

Can the cutter be used for plunge milling?
Yes. The cutter’s centre‑cutting geometry allows plunge entry, enabling direct slot starts without pre‑drilling for many applications.

What holder is recommended for secure clamping?
A Weldon holder or a collet chuck compatible with the 6 mm shank and drive flat is recommended to ensure secure clamping and prevent axial slippage during operation.

How many cutting edges does the tool have and what is the benefit?
The tool features three cutting edges, which promote smoother chip formation and more even load distribution, improving surface finish and process stability.

Is the cutter suitable for use in compact machining centres?
Yes. With a 5 mm cutting diameter and a 44 mm overall length, the cutter is suited to compact tool setups while maintaining sufficient rigidity for precision slotting.
