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

A mini slot cutter Ø 6 mm HSS‑Co8 designed for precision slotting and light milling in steel and cast iron, suitable for use in small series and workshop production.

• HSS‑Co8 construction for durability
• Three‑flute geometry for chip evacuation
• Weldon shank Ø 6 mm for secure clamping

Reliable high‑speed steel for demanding cuts

The cutter is manufactured from HSS‑Co8, a cobalt‑alloyed high‑speed steel that is designed to withstand higher temperatures and abrasion than standard high‑speed grades. This material choice results in improved wear resistance and extended tool life when machining harder workpiece materials. The tool is rated for machining materials up to approximately 800 N/mm², which means steel with medium tensile strength and many cast iron grades can be processed reliably. For buyers seeking measurable performance, the specified strength range provides a clear decision basis for material suitability.

Geometry engineered for precise slots and clean surfaces

A three‑flute configuration combined with centre cutting enables effective chip evacuation and good surface quality in slotting operations. The centre‑cutting design permits limited plunge cuts and helps avoid pre‑drilling in many small‑scale operations, while the right‑hand cut gives predictable chip flow and reliable cutting forces. The long design of the tool improves reach in deeper pockets and keyways, and the balanced flute geometry reduces vibration, promoting consistent finish and dimensional accuracy in each pass.

Secure clamping and straightforward tool integration

The cutter is supplied with a cylindrical shank featuring a drive flat — commonly referred to as a Weldon shank — which provides positive torque transmission in toolholders and prevents slippage under load. The Ø 6 mm shank diameter fits standard small‑tool holders and collet systems used in precision workshops and compact milling machines. Where repeatability and minimised set‑up time are priorities, the combination of a drive flat and standard shank diameter enables fast tool changes and reliable clamping forces for uninterrupted production.

Versatile workshop use with predictable results

This mini slot cutter shows very good suitability for cast iron and steel, while performance in non‑ferrous metals and stainless steel is conditional depending on feed, speed and cooling. Typical applications include slotting, keyways, grooves and small pocketing in prototype work, fixture production and repair jobs. The tool’s design supports efficient chip control and reduced rework, which translates into time savings and lower operating costs for small to medium runs. For operations that demand consistent results without high overhead, this cutter offers a pragmatic balance of durability and accessibility.

FAQ

What materials can be machined with this cutter?
The TECWERK mini slot cutter is very well suited to steel and cast iron and is conditionally suitable for non‑ferrous metals and stainless steel depending on cutting data.

Is the tool capable of plunge cutting?
Yes, the tool’s centre cutting geometry allows limited plunge operations, making it useful for slotting without pre‑drilling in many small applications.

What type of holder is required for secure clamping?
A holder that accepts a cylindrical shank with a drive flat is required; the cutter’s Weldon shank ensures positive torque transmission and prevents slippage.

How many flutes does the cutter have and why does that matter?
The cutter has three flutes; the three‑flute geometry improves chip evacuation and surface finish in slotting and reduces the chance of built‑up edge on tougher materials.

Can this tool be used for production and prototyping?
Yes, the long design and robust HSS‑Co8 composition make it suitable for workshop production, prototyping and small series where reproducible results are important.
