2.5mm Mini Slot Drill HSS-Co8 3-Flute Long, 3mm Cut, Right-Handed - TECWERK

Compact, precise cutting from a long HSS‑Co8 3‑flute cutter with Weldon shank delivers stable slotting in steel and cast iron up to ≈800 N/mm² — order directly via Metav Werkzeuge or consult the technical advisors for application guidance.

Mini slot milling cutter D2.5 mm HSS‑Co8, 3‑flute – TECWERK

The Mini slot milling cutter D2.5 mm HSS‑Co8 is a long, centre‑cut 3‑flute tool designed for precise slotting and plunge‑milling in low to medium strength materials.

• HSS‑Co8 for increased heat resistance
• 3‑flute design with centre cutting
• Weldon shank, 6 mm with drive flat
• Suited for steel and cast iron up to ~800 N/mm²

High‑performance cutting for medium‑strength materials

The long, HSS‑Co8 composition combines cobalt alloy toughness with high red hardness, meaning the tool maintains edge strength at elevated temperatures and under interrupted cuts. The 2.5 mm nominal diameter with a 3‑flute geometry provides a balance between chip removal and radial stability, while the centre cutting capability enables controlled plunging and slot entry. As a result, operators can expect consistent slot quality and extended tool life when machining steels and cast irons in the specified strength range.

Secure clamping and repeatable accuracy

A Weldon shank with 6 mm diameter and drive flat ensures positive clamping in holders with set screws, reducing slippage and minimising runout. The tool’s long configuration (total length 39 mm) and modest 3 mm cutting length extend reach for narrow slots and deeper setups without sacrificing rigidity. These characteristics contribute to improved surface finish and dimensional control, especially in small‑part production and toolroom applications where repeatability is essential.

Versatile use in workshop and production environments

The right‑hand cutting geometry and the 3‑flute centre‑cut design make this cutter suitable for a range of slotting and light milling tasks. Material suitability is clearly stated: steel — very good; cast iron — very good; non‑ferrous metals and stainless steel (inox) — conditionally suitable depending on machining parameters. The long version is particularly useful for accessing confined areas or producing elongated slots, while the compact diameter keeps material removal localised for precise finishing operations. Optimise speeds and feeds to match the workpiece and machine rigidity for best results.

FAQ

Which materials does this cutter machine best?
The TECWERK mini slot milling cutter is rated very good for steel and cast iron, with conditional suitability for non‑ferrous metals and stainless steel depending on cutting data.

Can the tool be used for plunge milling?
Yes — the centre‑cut 3‑flute geometry allows controlled plunge entry and slotting operations when using appropriate feeds and a stable setup.

What clamping is required for secure use?
Secure clamping in a milling holder with set screws is recommended; the Weldon shank with drive flat ensures a positive drive and reduced slippage.

What do the 3 flutes mean for chip control?
The three‑flute configuration balances chip evacuation and radial support, improving stability on small‑diameter slot cutters and aiding consistent surface finish.

Is this cutter suitable for deep narrow slots?
The long version with 39 mm total length offers increased reach for narrow or recessed slots while the 3 mm cutting length keeps material removal focused and controllable.
