6mm Slot Cutter DIN 844 HSS-Co8 Long 3-Flute Center Cutting 40° Helix, 6mm Shank - TECWERK

Take advantage of a durable HSS‑Co8 grade and a secure Weldon shank to achieve consistent slotting and plunge operations in long‑chip non‑ferrous materials; the combination of a 40° helix and three cutting edges increases material removal rates while maintaining surface finish.

Long three‑flute slot cutter DIN 844 Type W – Ø 6 mm, HSS‑Co8, Weldon (TECWERK)

Long three‑flute slot cutter DIN 844 Type W – Ø 6 mm by TECWERK, designed for efficient machining of long‑chip aluminium and other non‑ferrous metals

• HSS‑Co8 for high wear resistance
• 40° helix for improved chip evacuation
• Cylindrical Weldon shank with drive flat
• Centre‑cutting for plunge and slotting

Precise, repeatable slotting with a hardwearing cutting grade

The cutter is manufactured from HSS‑Co8, a cobalt‑alloyed high‑speed steel that delivers superior hardness and heat resistance compared with standard HSS; this means longer edge life when machining long‑chip materials. The three cutting edges distribute cutting forces more evenly, reducing chatter and extending tool life. For operations that combine slotting and light plunge work, the centre‑cutting geometry enables entry without a pilot, simplifying setup and reducing cycle steps while maintaining a consistent finish.

Secure clamping and stable run for accurate grooves

A cylindrical Weldon shank with drive flat provides reliable torque transmission in tool holders and collets commonly used in production workshops. The shank design helps prevent slippage during high feed machining, so groove width and position remain consistent across batches. Reduced vibration results in improved surface integrity on the workpiece, making the cutter suitable for precision components where dimensional stability is essential.

Faster material removal with controlled chip flow

The 40° helix promotes smooth chip formation and evacuation, particularly useful for aluminium and other soft, long‑chip non‑ferrous metals. Improved chip control reduces the risk of re‑cutting, which preserves the cutting edge and protects part surfaces. The three‑flute layout balances material removal rate and coolant access, enabling efficient cutting without sacrificing surface quality — a rational choice for production environments prioritising throughput and repeatability.

Application focus and workshop advantages

With a nominal diameter Ø 6 mm and long design, this cutter is optimised for slotting, face milling of narrow grooves and finishing operations in non‑ferrous metals. The tool’s specification follows DIN 844 Type W, offering compatibility with established machining standards. For workshops seeking to consolidate tooling without compromising capability, the cutter provides versatility across a range of aluminium alloys and other NE‑metals while simplifying inventory.

FAQ

Is this cutter suitable for plunging as well as slotting?
Yes. The centre‑cutting geometry allows plunge entry and straight slotting operations; the TECWERK long three‑flute cutter is specified for such combined tasks.

Which materials are recommended for this tool?
The tool is designed for aluminium and other non‑ferrous metals, where long chips are produced; HSS‑Co8 offers the hardness and heat resistance needed for these materials.

What does the Weldon shank offer in daily use?
A Weldon shank with drive flat ensures secure clamping and prevents slippage in collets or holders, improving repeatability and run‑out stability during machining.

How many flutes and what helix angle does the cutter have?
The cutter features three flutes and a 40° helix, a combination that balances removal rate with chip evacuation for improved productivity.
