6mm Mini Slot Cutter HSS-Co8 3-Edge Short With Weldon Shank, Right-Hand Cutting - TECWERK

Combining HSS‑Co8 construction with a Weldon shank and three‑flute geometry, this mini keyway cutter offers high rigidity and precise slotting for short‑run and prototype work; order the tool directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK Mini keyway cutter, 6 mm, HSS‑Co8, Weldon shank, 3‑flute (short)

A TECWERK mini keyway cutter 6 mm engineered for accurate milling of keyways and narrow slots in steel and cast iron, suitable for components with low to medium tensile strength up to approximately ~800 N/mm².

• HSS‑Co8 for enhanced wear resistance
• Three‑flute geometry for smooth slot finishes
• Weldon shank with drive flat for secure clamping
• Very good suitability for steel and cast iron

Precision slotting where rigidity matters

The short design and 6 mm shank reduce overhang and increase stiffness, which improves dimensional accuracy during slotting operations. Constructed from HSS‑Co8 (cobalt high‑speed steel), the cutter maintains edge strength under intermittent cutting loads; this supports consistent performance in milling narrow grooves and keyways. The centre‑cutting geometry enables plunge starts where necessary, while the compact tool body minimises vibration for superior surface quality and repeatable results.

Secure clamping and repeatable positioning for production

A Weldon shank with a dedicated drive flat ensures reliable torque transmission and repeatable tool positioning in set‑ups that demand quick tool changes. The three‑flute arrangement balances cutting forces and chip evacuation in constrained slots, reducing the risk of built‑up edge and improving cycle consistency. For small batch production or repair tasks, these attributes deliver faster set‑up times and lower scrap rates compared with tools that require higher overhang or complex clamping.

Material capability and practical limits explained

Designed for materials with low to medium tensile strength up to ~800 N/mm², the cutter is very well suited to machining steel and cast iron and is conditionally suitable for non‑ferrous metals and stainless steels. This means efficient removal and reliable tool life when used within the specified strength range; harder alloys or highly abrasive workpieces are outside the intended application. The specification clarifies where the tool provides economical performance and where alternative grades or coatings may be preferable.

Tool handling and workshop efficiency

The short version and right‑hand cutting direction provide a predictable cutting behaviour and straightforward toolpath programming when used on conventional milling machines or compact CNCs. The robust substrate of HSS‑Co8 gives improved resistance to thermal softening compared with standard high‑speed steels, supporting regrinding where applicable and reducing replacement frequency in routine workshop use. Overall, the combination of geometry and material reduces downtime and supports a steady throughput in maintenance and small‑scale production environments.

FAQ

What sizes are available for this cutter?
The described product is the TECWERK mini keyway cutter with a 6 mm shank (Article number 2000866016NW); alternate sizes are not listed in this data set.

Can the cutter be used for plunge cutting?
Yes, the centre‑cutting design permits plunge starts, so the cutter can be used for direct entry into the workpiece where required.

Is the tool appropriate for stainless steel applications?
Stainless steel is conditionally suitable for this cutter; the TECWERK tool performs best in steel and cast iron up to around 800 N/mm², while tougher stainless alloys may need specialised grades.

How does the Weldon shank benefit workshop use?
The Weldon shank with drive flat gives secure clamping and repeatable positioning, which reduces runout and improves process stability for slot milling operations.
