TECWERK Mini slot milling cutter Ø 2 mm — HSS‑Co8, 3‑flute, long, Weldon

A TECWERK Mini slot milling cutter designed for accurate 2 mm slots and small‑scale milling in steel and cast iron, suited to precision workshops and light production environments.

• HSS‑Co8 substrate for enhanced wear resistance
• 2 mm diameter for precise micro slotting
• Three‑flute, centre‑cut geometry for plunge milling
• Ø 6 mm Weldon shank with drive flat for secure clamping

Consistent micro‑slot accuracy for precision production

The combination of a 2 mm cutting diameter and a HSS‑Co8 substrate delivers consistent dimensional control when producing narrow slots and grooves. The tool’s geometry is optimised for repeatable performance on small features, reducing the need for secondary finishing and minimising rework. The three‑flute design balances cutting edges and stiffness, enabling stable results even in confined machining operations, while the long overall length supports access into deeper slots without compromising concentricity.

Material suitability explained for practical selection

This mini slot cutter is specified for operation up to approximately 800 N/mm², making it very well suited to carbon and alloy steels and very well suited to cast iron. Its performance on stainless steels and non‑ferrous metals is conditional; the cobalt‑alloyed substrate improves hot hardness and edge life but requires adapted feeds and speeds for optimal results. For delicate components where the material grade varies, the tool delivers predictable chip formation and surface integrity when matched to appropriate machining parameters.

Secure clamping and plunge capability for versatile use

A Weldon shank with a Ø 6 mm driver flat provides positive drive and prevents rotation in set screws, ensuring the cutter stays concentric under intermittent plunging and side loads. The centre‑cut geometry permits true plunge milling, enabling slot starts without pre‑drilling. Combined with correct toolholding—collets or Weldon‑capable chucks—the design reduces the risk of slippage and supports higher productivity through reliable clamping and quicker tool changes.

Durable cutting life with controlled chip evacuation

Thanks to the HSS‑Co8 composition, the tool offers improved wear resistance and thermal stability compared with standard high‑speed steel, extending service life in short‑run and repetitive tasks. The three‑flute arrangement improves chip evacuation in narrow slots, which helps maintain cutting edges and produces a superior surface finish in the slot base. For production contexts that demand repeatable outcomes, this micro slot cutter supports consistent part quality and reduces downtime related to tool wear.

FAQ

Is this cutter suitable for plunge milling?
The TECWERK mini slot milling cutter features a centre‑cut three‑flute geometry that allows plunge milling and direct slot starts without prior drilling.

Which materials are best machined with this tool?
The tool performs very well on carbon and alloy steels and on cast iron; stainless steel and non‑ferrous metals are conditionally suitable and require adjusted machining parameters.

What clamping system is recommended for secure use?
Use collets or Weldon‑capable chucks with the Ø 6 mm Weldon shank and drive flat to ensure positive drive and avoid slippage during interrupted cuts.

How does the HSS‑Co8 composition affect tool life?
The HSS‑Co8 alloy increases hot hardness and wear resistance, which improves edge retention in short‑run and repetitive milling compared with standard high‑speed steel.

Can the cutter be used for very narrow or deep slots?
The long overall length and the 2 mm diameter permit access into deeper slots while maintaining concentricity; correct clamping and conservative feeds help prevent deflection.
