Slot milling cutter DIN 844 Type W, 16 mm, HSS‑Co8, Weldon shank — TECWERK

Slot milling cutter DIN 844 Type W, 16 mm, HSS‑Co8, long, designed for machining long‑chip aluminium and non‑ferrous metals with secure Weldon toolholding

• HSS‑Co8 for high toughness
• 3‑flute design with centre cut
• Weldon shank, 16 mm, secure clamping
• 40° helix angle for efficient chip flow

High‑speed performance for continuous production

The HSS‑Co8 alloy delivers elevated heat resistance and wear performance compared with standard high‑speed steels, which translates into more consistent cutting on non‑ferrous materials. The combination of a 3‑flute geometry and a 40° helix angle promotes smooth chip evacuation and stable cutting forces, reducing the risk of built‑up edge when machining long‑chip aluminium. This results in reliable surface quality and predictable tool life in serial or single‑piece production environments.

Secure clamping and reliable concentricity

A Weldon shank with a cylindrical profile and driving flat ensures positive tool retention in set screws or hydraulic chucks, keeping concentricity stable under load. The 16 mm shank diameter provides a robust connection to the spindle, reducing vibration and runout during slotting operations. Together these features maintain dimensional accuracy of the machined slot and lower the likelihood of premature tool wear, supporting repeatable production tolerances.

Designed for plunge and slot milling in non‑ferrous materials

The cutter’s centre cut (plunge capability) allows safe vertical engagement for slotting and pocketing tasks, while the tool’s geometry is optimised for long‑chip aluminium and other non‑ferrous metals. A cutting length of approximately 15 mm on the long version makes the tool suitable for deeper slots and stepped features without sacrificing chip clearance. The DIN 844 Type W specification signals an industry‑standard form factor for compatibility with existing machining processes.

Practical handling and process benefits

Using a cutter with the right material and geometry reduces cycle time and the need for frequent tool changes. The long design paired with the 3‑flute layout balances material removal with effective chip evacuation, which is particularly important when machining aluminium alloys that produce continuous chips. Maintenance is straightforward: standard sharpening procedures for cobalt‑enriched HSS restore the cutting edges, and the robust shank design supports repeated clamping without loss of accuracy.

FAQ

What materials are best cut with this slot milling cutter?
The cutter is optimised for long‑chip aluminium and other non‑ferrous metals; the HSS‑Co8 grade in the TECWERK slot milling cutter supports reliable cutting performance in these materials.

Can the cutter be used for plunge milling?
Yes, the centre cut design permits plunge‑type engagement, so the TECWERK Type W cutter can be used for vertical entry and slotting tasks.

What clamping is recommended for best concentricity?
Secure clamping with a suitable set‑screw holder or hydraulic chuck is recommended to exploit the Weldon shank; the 16 mm shank on SKU 2000866310NW provides a stable connection for accurate operation.

How does the 40° helix angle affect machining?
A 40° helix angle improves chip evacuation and produces smoother cutting when machining ductile, long‑chip materials, reducing build‑up and enhancing surface finish with this cutter.

Is the cutter suitable for high‑speed machining?
The HSS‑Co8 composition offers higher thermal resistance than conventional HSS, making the cutter appropriate for higher‑speed feeds and moderate spindle speeds when machining non‑ferrous alloys.
