TECWERK Slot Drill DIN 844 Type N Ø6 mm — HSS‑Co8, TiCN Coating, Weldon Shank

The TECWERK Slot Drill DIN 844 Type N Ø6 mm is a long, centre‑cutting three‑flute slotting cutter designed for precise groove and slot machining in steel, stainless steel and cast materials.

• HSS‑Co8 substrate for high wear resistance
• TiCN coating for extended tool life
• Centre‑cutting three‑flute geometry
• Weldon shank with drive flat for secure clamping

Durable substrate and coating for prolonged service life

The combination of HSS‑Co8 substrate and TiCN coating provides a balance of toughness and wear resistance that suits serial and mixed production. Cobalt‑alloyed high‑speed steel increases heat resistance and fracture toughness, while the titanium carbonitride finish reduces adhesive wear and friction on the cutting edges. This pairing permits machining of workpieces up to 800 N/mm² with uncoated cutters and up to 1000 N/mm² when the coating is applied, translating into fewer tool changes and more predictable cycle times. The result is lower overall tooling costs and improved uptime for production lines.

Precise geometry and secure clamping for clean slots

The cutter’s three‑flute, centre‑cutting design enables effective slotting and plunge operations with reduced vibration and reliable chip evacuation for many common workshop tasks. A Weldon shank with a drive flat ensures consistent torque transfer and stable clamping in standard collets and holders. The tool is available with a 6 mm shank and features a relief/grind measure of 5.5 mm that supports cutting stability on longer reaches. Nominal diameters offered (9, 11, 13, 15 mm) follow machine tolerances h10 for critical sizes and e8 for remaining dimensions, providing reproducible fit and repeatable results in precision setups.

Broad application range and material suitability

Designed primarily for demanding ferrous applications, the cutter shows very good suitability for steel, stainless steel (INOX) and cast materials, while use on non‑ferrous metals and special alloys is possible under adapted cutting data and reduced feeds. The long version offers reach for deeper grooves and interrupted cuts; however, adherence to appropriate speeds and feeds is essential to exploit the centre‑cutting capability without compromising tool life. This makes the tool a practical choice for industrial workshops, maintenance departments and contract manufacturers seeking a versatile slotting solution that balances productivity and reliability.

FAQ

What materials is this slot drill best suited for?
The TECWERK slot drill with HSS‑Co8 and TiCN coating is very well suited to steel, stainless steel and cast materials; non‑ferrous metals and special alloys can be machined with adapted cutting data.

Can the tool perform plunge cuts or only peripheral milling?
The centre‑cutting design of the slotting cutter enables plunge operations as well as slotting, making the tool suitable for combined milling and drilling tasks.

How does the Weldon shank benefit the machining process?
A Weldon shank with drive flat ensures secure clamping and reliable torque transmission in standard holders, improving stability during slotting operations with the TECWERK cutter.

Are the nominal diameters supplied to tight tolerances?
Yes, the available nominal diameters (9, 11, 13, 15 mm) are manufactured to tolerance h10 for critical sizes, with remaining dimensions to e8, ensuring reproducible fit and predictable results.
