Slot drill Type N D.8 mm HSS‑Co8 TiCN — long, Weldon shank, 2‑flute (TECWERK)

The Slot drill Type N D.8 mm HSS‑Co8 TiCN is a long two‑flute centre‑cutting milling cutter optimised for slotting and axial operations in medium‑strength steels, stainless steel and cast iron.

• Long two‑flute design for axial centre cutting
• TiCN coating for extended tool life
• Solid HSS‑Co8 for high temperature resilience
• Weldon shank Ø10 mm with drive flat

High‑performance substrate and coating for longer production runs

The combination of a HSS‑Co8 substrate and a TiCN surface treatment delivers a stable cutting edge and increased resistance to abrasive wear, which translates into fewer tool changes and higher machine uptime. For workshops processing a variety of ferrous materials, this material pair provides consistent performance and helps maintain dimensional integrity during longer cycles. The coating reduces built‑up edge and improves heat resistance, making the cutter suitable for continuous or intermittent milling where thermal load is a factor.

Secure clamping and extended reach reduce setup risk

Equipped with a Weldon shank (Ø10 mm) and a generous overall length of 88 mm with an effective working length of 44 mm, this long version ensures reliable clamping and the reach required for deeper grooves or recessed features. The Weldon flat prevents rotation in the tool holder under heavy loads, so clamping security and repeatability are improved. This design reduces the risk of tool slippage, lowers the likelihood of rework and supports consistent part quality across batches.

Two‑flute centre cutting geometry for efficient groove creation

The two‑flute, centre‑cutting geometry permits axial entry and clean slotting with a short cutting length of 2 mm, while the right‑hand cutting direction provides predictable chip flow for most conventional setups. The reduced flute count improves chip evacuation in narrow slots and helps maintain a steady feed rate, which is advantageous when machining medium‑strength steels and stainless grades. The result is precise slot edges and fewer burrs, lowering finishing effort and saving time on secondary operations.

Material suitability and process advantages for industrial applications

This cutter is evaluated as very good for steel, very good for stainless steel (INOX) and very good for cast iron, with conditional suitability for non‑ferrous metals and special alloys; it is designed to machine materials up to roughly 1000 N/mm². For production environments prioritising dependability, the tool offers a balanced mix of wear resistance and toughness, which makes it well suited to repeated slotting tasks in toolrooms, maintenance workshops and light production cells. Clear specification and predictable performance support process planning and reduce downtime.

FAQ

What materials can be machined with this slot drill?
The slot drill Type N D.8 mm HSS‑Co8 TiCN (TECWERK, SKU 2000866160NW) is very good for steel, stainless steel and cast iron; it is conditionally suitable for non‑ferrous metals and special alloys.

Is the cutter suitable for plunge or axial entry operations?
Yes, the two‑flute centre‑cutting geometry of the TECWERK slot drill allows axial entry, though the specified cutting length of 2 mm makes it most suitable for shallow plunge cuts and slot starts.

How is the tool clamped in the holder?
Clamping is by the Weldon shank (Ø10 mm) with a drive flat, which secures the slot drill reliably under torque and reduces the risk of rotation in the tool holder.

What benefits does the TiCN coating provide?
The TiCN coating on the HSS‑Co8 substrate enhances wear resistance and heat tolerance for the slot drill Type N, extending tool life and improving performance in longer production runs.

What cutting direction and flute count does the tool have?
The TECWERK slot drill is right‑hand cutting and features two flutes, optimised for efficient chip evacuation in narrow slots.
