Mini slot milling cutter D3 mm HSS‑Co8, 3‑flute (short), Weldon shank — TECWERK

The Mini slot milling cutter D3 mm HSS‑Co8 is a short, centre‑cutting three‑flute tool designed for fine slotting and keyway work in steel and cast iron with minimal setup.

• HSS‑Co8 three‑flute short design
• Weldon shank, 6 mm shank diameter
• Centre cutting for plunging and slotting
• Suitable for steels up to 800 N/mm²

Precise slotting that reduces setup time and rework

The short 3‑flute geometry with centre cutting enables direct plunging and clean slot entry, reducing the need for pilot operations and additional fixturing. Produced from HSS‑Co8, the cutter maintains edge integrity under intermittent cutting and offers improved wear resistance compared with standard high‑speed steels. This combination of material and geometry translates into repeatable slot dimensions and fewer rejected parts, which supports reliable production output in toolrooms and CNC milling cells.

Secure clamping and compatibility with compact spindles

A Weldon shank with a 6 mm diameter provides a secure clamping surface for high torque transmission in compact toolholders. The cylindrical shank with drive flat minimises slippage and enables rapid tool changes while preserving concentricity. The short overall length contributes to reduced overhang, improving rigidity and stability at higher feed rates. Together these features support efficient machining cycles and consistent surface finish when using smaller milling setups or vertical milling machines.

Material range and recommended applications

The cutter is optimised for materials of low to medium strength and is rated for effective machining of steel up to approximately 800 N/mm²; cast iron is also very well suited. Performance on stainless steel and certain non‑ferrous alloys is conditional and may require adjusted feeds or toolpaths. Typical applications include precision slotting, keyway machining, pocketing small features and fine finishing operations where tool rigidity and accurate depth control are essential. Where higher alloy or stainless steels are involved, consider adjusted process parameters or alternative coatings and grades.

Integrating the tool into production and maintenance routines

Minimal maintenance is required beyond usual regrinding procedures for high‑speed steel tools. Using a short, centre‑cutting mini cutter reduces cycle variability and often shortens set‑up time, allowing quicker changeovers between jobs. Where tool life needs extending, select cutting parameters that balance speed and feed with the carbide‑lean nature of HSS‑Co8. For customers seeking to standardise small slotting tools across multiple benches, the combination of consistent geometry and Weldon shank simplifies inventory and tooling lists while maintaining machining quality.

FAQ

Is the cutter suitable for plunging operations?
The TECWERK mini slot milling cutter D3 mm is centre cutting, allowing plunging into material for direct slotting and reduced need for pre‑drilling.

What machines are compatible with the Weldon shank?
The 6 mm Weldon shank is compatible with standard collet chucks and Weldon‑style holders used on compact mills and milling heads where a drive flat is required.

Can the tool machine stainless steel effectively?
Stainless steel is conditionally suitable; the cutter will machine inox with adjusted feeds and speeds, but for prolonged runs or hard grades consider a coated or carbide alternative.

How long is the cutting length and what accuracy can be expected?
The cutting length is 3 mm; the short design enhances rigidity and supports consistent slot dimensions when proper clamping and cutting parameters are used.

What are the primary applications for this tool?
Typical uses include fine slotting, keyway cutting and small pocketing in steel and cast iron, where precision and minimal setup are priorities.
