TECWERK short three‑flute slot drill DIN 844, 12 mm — HSS‑Co8, Weldon shank

A TECWERK short three‑flute slot drill engineered for precision slotting and light plunge operations in aluminium and non‑ferrous materials.

• HSS‑Co8, very good for non‑ferrous metals
• Weldon shank with drive flat
• Three‑flute, centre cutting geometry
• 40° helix angle for long‑chip evacuation

Faster, cleaner cuts in non‑ferrous materials

The high‑alloy HSS‑Co8 composition provides increased red hardness and wear resistance, keeping cutting edges sharper for longer during repetitive aluminium machining. The three‑flute arrangement balances effective chip formation with a larger core for rigidity, while the 40° helix promotes continuous, controlled chip flow — especially important when machining long‑chip aluminium and other soft, ductile non‑ferrous metals. These combined attributes reduce the need for frequent tool changes and help maintain consistent surface finish in production runs.

Secure clamping and stable performance for precise slots

A Weldon shank with drive flat ensures positive engagement in set‑screw toolholders and prevents slippage under torque, which is critical when using a short cutter in interrupted cuts. The DIN 844 Type W short format and compact effective length lend themselves to stiff setups where vibration must be minimised. The cutter’s centre‑cutting geometry allows limited plunge and slotting operations without prior drilling, offering practical versatility in fixture work and small‑batch production while maintaining positional accuracy.

Predictable tool life and workshop compatibility

The short three‑flute design presents a cost‑effective solution for workshops seeking reliable, repeatable slotting without complex process changes. With a standard 12 mm shank diameter and common DIN specification, the cutter integrates easily into existing toolholders and collet systems, simplifying logistics and inventory. The robust material choice and geometric features translate into dependable service life and consistent component quality — attributes valued by procurement and production planners looking to reduce downtime and ensure process stability.

FAQ

Which materials is this slot drill best suited for?
The TECWERK short three‑flute slot drill (SKU 2000866284NW) is optimised for long‑chip aluminium and other non‑ferrous metals, offering very good suitability for such materials due to its HSS‑Co8 composition and 40° helix angle.

Is the shank compatible with standard clamping systems?
Yes, the cutter features a Weldon shank with drive flat, 12 mm in diameter, which is compatible with set‑screw holders and clamping systems designed for Weldon‑style shafts.

Can the cutter perform plunge operations or only peripheral milling?
The three‑flute, centre‑cutting geometry allows for limited plunge and slotting operations as well as peripheral milling, making it suitable for both short slotting and through‑cut passes in non‑ferrous materials.

Does the tool come with a coating?
The TECWERK slot drill is supplied uncoated; the base HSS‑Co8 material provides inherent wear resistance without an additional coating.

What standard and SKU identify this tool?
The cutter conforms to DIN 844 Type W and is listed under SKU 2000866284NW, supplied by TECWERK.
