TECWERK Slotting cutter DIN 844 Type W, 3 mm — HSS‑Co8, Weldon shank

A TECWERK Slotting cutter DIN 844 Type W designed for precise slotting and grooving in aluminium and other non‑ferrous metals

• HSS‑Co8 for enhanced wear resistance
• 40° helix for improved chip evacuation
• Weldon shank with drive flat for secure clamping

High‑performance geometry for non‑ferrous machining

The tool is manufactured to DIN 844 standards and features HSS‑Co8 high‑speed steel with cobalt for increased thermal stability and wear resistance. The three‑flute arrangement and centre cutting geometry make the cutter suitable for slotting and light plunging operations; this design reduces vibration and distributes cutting forces evenly, allowing consistent material removal when working with aluminium and similar alloys. Machinists will find the combination of material and geometry particularly effective where repeatable slot accuracy is required.

Predictable chip flow and surface finish

A 40° helix angle promotes controlled chip formation and evacuation, which is especially beneficial when machining long‑chip non‑ferrous materials. The steeper helix reduces radial cutting forces and encourages small, continuous chips rather than long, stringy swarf, improving surface quality and lowering the risk of re‑cutting. Where surface finish matters, the cutter’s geometry contributes directly to a cleaner edge and fewer manual finishing steps, increasing process efficiency on small to medium batch runs.

Secure clamping and machine compatibility

The cutter is supplied with a Weldon shank and a 6 mm shank diameter, plus a drive flat for positive fixation in set screws and collet systems. This configuration ensures the tool remains stable under load and minimises slippage in vertical and horizontal milling heads. The tool’s right‑hand cut is optimised for conventional spindle rotation; it is therefore compatible with standard toolholders and familiar set‑ups used in general workshop and light industrial CNC applications.

Practical benefits for workshop workflows

Long‑length tooling and a centre‑cutting profile support deeper slotting tasks without frequent tool changes, reducing downtime and simplifying setup. The cutter is described as long in specification, which increases reach for grooves and internal features in non‑ferrous workpieces. Given the focus on durability and chip control, this slotting cutter is a sensible choice for workshops seeking reliable throughput on aluminium components while keeping fixture and machine adjustments straightforward.

FAQ

What materials is this cutter best suited for?
The TECWERK slotting cutter (SKU 2000866294NW) is specified for aluminium and other non‑ferrous metals and offers very good suitability for these materials thanks to its HSS‑Co8 composition and flute geometry.

Can the cutter be used for plunging operations?
Yes, the centre‑cutting design of the TECWERK slotting cutter allows for limited plunging as well as traditional slotting, though prolonged plunging should be matched to machine capabilities and feed strategy.

Which shank size and clamping method are required?
The tool has a 6 mm shank with a Weldon drive flat; secure clamping with a set screw or compatible collet is recommended to ensure stability during milling.

How does the helix angle affect machining performance?
The 40° helix promotes smoother chip evacuation and reduced cutting forces, which improves surface finish and reduces the tendency for long chips when machining long‑chip aluminium alloys.

Is the cutter compatible with standard milling holders?
Yes, the Weldon shank and cylindrical form make the cutter compatible with common milling holders and fixtures used in workshop CNC and manual milling setups.
