Slot milling cutter DIN 844 Type W, Ø10 mm, HSS‑Co8 — TECWERK

The Slot milling cutter DIN 844 Type W is a long, centre‑cutting end mill designed for machining long‑chip aluminium and other non‑ferrous metals in production and workshop environments

• HSS‑Co8 for enhanced wear resistance
• Centre‑cutting for plunge and slot milling
• Weldon shank Ø 10 mm for secure clamping
• Excellent for aluminium and non‑ferrous metals

Consistent performance in aluminium and non‑ferrous alloys

The long version of this slot milling cutter is manufactured from HSS‑Co8, a cobalt‑alloyed high‑speed steel that offers improved heat resistance and edge stability during continuous cutting. The tool’s geometry, featuring a 40° helix and 3 flutes, promotes the formation of long, controllable chips when machining soft, ductile materials. That combination reduces built‑up edge and helps maintain surface quality in profiles and through‑slots. For production settings where repeatability matters, the tool’s composition and flute design translate directly into fewer tool changes and steadier cycle times.

Secure clamping and centre‑cutting capability explained

A Weldon shank with drive flat provides reliable torque transmission for heavier engagement, while the Ø10 mm shank diameter suits standard collets and Weldon‑flat holders. The cutter’s centre‑cutting capability enables safe plunge starts and pocketing operations without requiring a preceding pilot hole, which simplifies machining sequences and shortens setup. The combination of a cylindrical shank with a positive drive surface ensures that axial forces are transferred cleanly, reducing chatter and improving dimensional stability in slotting tasks.

Geometry and handling that improve productivity

With its DIN 844 Type W specification and long reach, the tool delivers accessibility in deep slotting and extended features. The 3‑flute layout balances material removal rate and chip evacuation: more flute volume than a two‑flute design while still offering clear chip space for long‑chip materials. The 40° helix angle encourages smooth cutting action and lowers axial vibration, which benefits tool life and workpiece finish. For machining schedules that prioritise throughput, this geometry offers a pragmatic compromise between metal removal and surface integrity.

Application guidance and workshop integration

Designed specifically for long‑chip aluminium and other non‑ferrous metals, the cutter is well suited to tasks such as slotting, pocketing and profile milling in production and maintenance shops. The cylindrical shank with drive flat supports secure mounting in common toolholders, and the centre‑cutting design enables versatile toolpaths. For process planning, consider moderate cutting speeds and positive feed to encourage continuous chip removal; trial cuts on representative stock are recommended to establish optimal parameters for the specific alloy and machine rigidity.

FAQ

Is this cutter suitable for aluminium and similar non‑ferrous materials?
Yes. The TECWERK slot milling cutter is specified as very well suited for long‑chip aluminium and other non‑ferrous metals, thanks to its HSS‑Co8 composition and flute geometry.

What is the shank size and what clamping is recommended?
The tool has a Ø 10 mm shank with a Weldon drive flat; secure clamping in a suitable Weldon holder or collet with flat is recommended for torque transmission.

Can the cutter perform plunge cuts?
Yes. The centre‑cutting design allows plunge starts and pocketing operations without a pilot hole, making the cutter versatile for combined slotting and pocketing tasks.

How many flutes does the cutter have and why does that matter?
The cutter comes with 3 flutes, a balance that supports higher material removal while maintaining chip clearance for long‑chip materials like aluminium.

Which standard does the tool conform to?
This cutter follows DIN 844 Type W specifications, indicating its form and intended application for slotting and groove milling.
