TECWERK slot drill Type N, 6 mm — HSS‑Co8, TiCN-coated, Weldon shank, 2 flutes

A TECWERK slot drill Type N 6 mm designed for precision slotting and centre-cut machining in steel, stainless steel and cast components

• HSS‑Co8 base material for high wear resistance
• TiCN coating for improved durability and heat resistance
• Weldon shank with drive flat for secure clamping
• Centre-cut, 2‑flute long design for slotting

Consistent life and heat resistance for demanding production

The combination of HSS‑Co8 (cobalt-alloyed high-speed steel) and TiCN (titanium carbonitride) coating yields a balance of toughness and surface hardness that benefits repeated slotting operations. The cobalt alloy increases red-hardness and wear resistance compared with conventional high-speed steels, while the TiCN layer reduces friction and improves thermal stability. This makes the tool suitable for continuous use and helps to reduce unexpected tool changes, contributing to a smoother production flow.

Precise cutting geometry for reliable slot performance

A centre-cut geometry and 2 flutes enable controlled chip evacuation and allow the cutter to start slots without pre-drilling, which is especially useful for keyway and slot milling. The cutter is right‑hand cutting and offers a short cutting length for precise, shallow slots and a longer effective reach for deeper set-ups. These characteristics provide measurable productivity gains when machining components up to approximately 1000 N/mm², including stainless grades and cast materials.

Secure clamping and dimensions that match common toolholders

The Weldon shank with drive flat ensures a secure, slip-free grip in compatible holders, avoiding runout and vibration during slot milling. The tool has a 6 mm shank diameter and an overall length of 68 mm, with an effective length of 30 mm and a relief dimension of 5.35 mm, making it suitable for standard collet and Weldon-holder arrangements. The long version design offers additional accessibility in fixtures where extra reach is required without compromising stability.

Process efficiency and material suitability explained

Thanks to the material recommendations, the cutter excels at machining steel, stainless steel (INOX) and cast iron, while non-ferrous alloys and special alloys are conditionally suitable depending on cutting data. The short cutting length and two-flute configuration promote predictable chip formation and easy swarf removal, reducing the risk of workpiece heat build-up. For occasional work on non-ferrous or specialised alloys, adjust feeds and speeds to match the material characteristics and to preserve the coating performance.

FAQ

What materials is this slot drill suitable for?
The TECWERK slot drill Type N 6 mm (SKU 2000866158NW) is very well suited for steel, stainless steel (INOX) and cast iron; non-ferrous and special alloys are conditionally suitable depending on cutting data.

Can this cutter start a slot without pre-drilling?
Yes, the centre-cut geometry and two-flute design allow the TECWERK slot drill Type N to plunge and start slots, making it practical for keyways and short slotting operations.

Which holder is required for secure clamping of this tool?
A Weldon holder or compatible collet system that accommodates a 6 mm shank and drive flat is recommended for stable clamping of the TECWERK slot drill Type N, ensuring minimal runout and vibration.

Does the TiCN coating improve tool life for stainless steel?
The TiCN coating on the TECWERK slot drill Type N enhances wear resistance and reduces friction, which is beneficial when machining stainless steel and helps extend service intervals.

What cutting data should be considered for hardened steels?
This cutter is optimised for materials up to about 1000 N/mm²; for pre-hardened or very high-strength steels, adjustments to feed and speed are necessary and tool life should be monitored.
