Mini slot cutter D.3 mm – HSS‑Co8, 3‑flute, long (TECWERK)

The Mini slot cutter D.3 mm HSS‑Co8 Weldon Z.3 long is a long, three‑flute, centre‑cutting tool designed for precise slotting and groove milling in steels and cast iron up to approximately 800 N/mm².

• HSS‑Co8 for extended wear resistance
• 3‑flute centre‑cutting geometry for plunge milling
• Weldon shank with drive flat for secure clamping
• Excellent for steel and cast iron up to 800 N/mm²

Consistent precision for small‑feature groove milling

The long version of this mini slot cutter combines a Ø 3 mm cutting diameter with a 3‑flute geometry and centre cutting capability, allowing accurate slot and groove creation even when a plunge is required. The cobalt‑alloyed high‑speed steel (HSS‑Co8) offers improved heat resistance and wear performance compared with plain HSS, which supports stable dimensional accuracy and longer tool life in serial work. The three cutting edges distribute chip load and promote smoother cutting action, reducing vibration and improving surface finish on narrow grooves.

Clear recommendations for material use and machining strategy

Selection of this tool is guided by material compatibility: steel and cast iron are very well suited, while non‑ferrous metals and stainless steel are marked as conditionally suitable; in such cases reduced feed and adjusted cutting speeds are recommended to avoid workhardening or premature wear. The tool is specified for components up to about 800 N/mm², so it is well matched to common structural and cast materials. The right‑hand cutting direction and centre‑cutting geometry enable safe plunging operations; however, for softer or gummy materials a pecking strategy and controlled chip evacuation prolong tool life.

Secure clamping and workshop integration for reliable production

The Weldon shank with a drive flat and a 6 mm shank diameter ensures positive engagement in set screws or Weldon holders, preventing slippage during heavy engagement or interrupted cuts. The long tool length offers reach for deeper grooves without frequent tool changes, while maintaining rigidity when combined with correct holder overhang practices. For consistent results, use appropriate coolant or lubricant and monitor chip removal when machining deeper pockets; the combination of tool geometry and robust shank design supports efficient integration into standard milling setups.

FAQ

What materials is this cutter best suited to?
The TECWERK mini slot cutter is very well suited for steel and cast iron, with conditional suitability for non‑ferrous metals and stainless steel; suitability is given up to around 800 N/mm².

Can the tool be used for plunge or centre milling?
Yes — the cutter features centre cutting geometry and a three‑flute design, which permits controlled plunge operations and slotting.

What shank size and holder type are required?
The tool has a 6 mm Weldon shank with a drive flat and is intended for Weldon holders or collets compatible with a 6 mm shank and set‑screw clamping.

How many flutes does the cutter have, and what benefit does that provide?
The cutter has three flutes, which balance cutting load and chip evacuation for improved surface finish and stability in narrow slots.

Is this cutter suitable for deep slotting applications?
The long version of the cutter is designed for increased reach and deeper grooves; appropriate machining strategy (reduced feed, coolant, pecking) is advised for best longevity.
