Slot drill Type N Ø8 mm, HSS‑Co8, TiCN, Weldon – TECWERK

The Slot drill Type N Ø8 mm HSS‑Co8 TiCN Weldon is a long two‑flute slotting cutter designed for machining slots and shallow plunges in steel, stainless steel and cast iron.

• HSS‑Co8 substrate for high thermal resistance
• TiCN coating for reduced friction and longer life
• Weldon shank with drive flat for secure clamping
• Centre‑cut two‑flute geometry for efficient slotting

Extended tool life through high‑alloy steel and hard coating

The combination of HSS‑Co8 (a cobalt‑alloyed high‑speed steel) and a TiCN coating increases resistance to heat and abrasive wear, which translates into longer service intervals and more consistent part quality. The hard coating reduces friction at the cutting edge and improves surface finish, while the cobalt content of the substrate maintains toughness under intermittent loads. This balance of wear resistance and toughness is particularly valuable for production runs where tool change‑over and rework must be minimised.

Secure clamping and geometry that supports reliable slotting

A Weldon shank with a drive flat ensures positive retention in set‑screw holders, reducing the risk of slippage during interrupted cuts. The centre‑cut design allows limited plunging into material, while the two flutes provide efficient chip evacuation in slotting operations. Together these features reduce chatter and promote concentricity, supporting repeatable slot widths and better dimensional control on the workpiece.

Proven suitability for common workshop materials

This long slotting cutter is specified for machining materials up to approximately 1000 N/mm², making it very well suited to carbon steel, stainless steel and cast iron in everyday workshop and light industrial applications. Non‑ferrous metals and special alloys are noted as conditionally suitable; machining parameters should be adapted accordingly. Right‑hand cutting geometry and the centre‑cut capability make the tool a practical choice for tasks that demand both slotting and occasional plunge entry.

Practical benefits for workshop efficiency

The extended reach of the long variant permits deeper slots without frequent re‑setting, reducing downtime and increasing throughput. The coating and substrate combination contributes to predictable wear behaviour, which supports planned maintenance intervals and cost control. For machining centres with suitable clamping and rigid setups, this cutter delivers a balance of precision and robustness that simplifies process planning and helps maintain consistent surface quality across batches.

FAQ

Is this cutter suitable for stainless steel?
Yes. The Slot drill Type N Ø8 mm with an HSS‑Co8 substrate and TiCN coating is specified as very well suited for stainless steel machining, combining wear resistance and toughness for reliable performance.

Can the cutter be used for plunge cutting?
The centre‑cut geometry allows limited plunging and makes the tool suitable for slotting operations that require occasional plunge entries, although it is primarily optimised for slot milling.

What clamping system is required for the Weldon shank?
The Weldon shank is designed for secure retention in holders with a set‑screw or compatible Weldon holders, ensuring positive drive and reduced risk of slippage during interrupted cuts.

What advantages does the TiCN coating provide?
TiCN reduces friction at the cutting edge, improves wear resistance and contributes to a better surface finish, which together extend tool life and reduce the need for frequent replacements.

Which materials are less suitable for this cutter?
Non‑ferrous metals and certain special alloys are listed as conditionally suitable; for those materials, cutting parameters should be adapted and trial cuts recommended to confirm performance with the Slot drill Type N Ø8 mm (SKU 2000866160NW).
