Long slot milling cutter DIN 844 Type W, Ø 8 mm (HSS‑Co8) — TECWERK

A long slot milling cutter (DIN 844, Type W) designed for slotting and plunge machining of long‑chipping aluminium and non‑ferrous metals, featuring a cylindrical shank with Weldon drive flat and a 40° helix for effective chip evacuation

• HSS‑Co8 construction for high heat resistance
• Three‑flute, centre‑cutting geometry for plunge milling
• Weldon shank with drive flat for secure clamping
• Optimised for aluminium and non‑ferrous metals

Faster, cleaner slotting with high‑performance material

The cutter is manufactured from HSS‑Co8 (high‑speed steel with 8% cobalt), which increases red hardness and wear resistance compared with standard HSS. This material choice, combined with the three‑flute, centre‑cutting geometry and a 40° helix, enables faster feeds and improved chip flow when machining long‑chipping aluminium and similar alloys. The result is a cleaner slot surface and reduced risk of built‑up edge, translating into fewer reworks and higher process efficiency for production or workshop tasks.

Stable clamping and extended reach for deep slots

A Weldon (drive‑flat) cylindrical shank with a 10 mm diameter provides positive drive and minimises slippage in the toolholder, improving concentricity under cutting forces. The tool’s long version is suited to deeper groove and slot operations where extended reach is required; the specified 7.5 mm relief/cutting length gives clearance while maintaining rigidity. Together these design features reduce vibration and deflection, which preserves tool life and supports consistent tolerances in repetitive machining.

Application focus: productivity and predictable results

Specifically engineered for long‑chip materials, the cutter excels in machining aluminium and other non‑ferrous metals, offering reliable performance for die shops, fabrication and component manufacturing. The centre‑cutting capability allows controlled plunging as well as peripheral milling, shortening process chains where a single tool can perform both operations. For buyers seeking steady throughput, this combination of geometry and material delivers measurable productivity gains and predictable tool replacement intervals.

FAQ

Is this cutter suitable for plunge milling into aluminium?
Yes. The long slot milling cutter is centre‑cutting and designed for plunge as well as peripheral milling in long‑chipping aluminium and similar non‑ferrous alloys.

What material is the tool made from and why does it matter?
The cutter is made from HSS‑Co8, which contains 8% cobalt to improve heat resistance and wear behaviour under higher cutting temperatures, supporting longer life in continuous aluminium machining.

Which shank size and clamping style are required?
The tool has a 10 mm cylindrical shank with a Weldon drive flat, intended for holders that accept a drive‑flat configuration to ensure secure transmission of torque.

Can this cutter handle other non‑ferrous metals besides aluminium?
Yes. The geometry and material make the cutter well suited to a range of non‑ferrous metals, providing effective chip control and surface finish across typical alloys.

What distinguishes the long version from a standard length cutter?
The long variant offers increased reach for deeper slots and grooves while maintaining the same cutting geometry, trading some stiffness for the ability to machine features that require extended tool projection.
