TECWERK Slot drill to DIN 844 Type N, 10 mm — HSS‑Co8, Weldon shank, 3‑flute, long

The TECWERK slot drill designed for plunge milling and slotting in steels and cast iron, following DIN 844 Type N for reliable industrial use.

• HSS‑Co8 for high wear resistance
• Centre‑cut for plunge milling
• Weldon shank with driving flat
• Very good for steel and cast iron

Productivity gains from a centre‑cut, three‑flute geometry

The combination of a centre‑cutting tip and three‑flute design delivers efficient chip evacuation and stable cutting when plunging and slotting. This geometry reduces the number of tool changes and minimises non‑productive time, especially in batch production or repair work. The HSS‑Co8 substrate provides improved red‑hardness and wear resistance compared with conventional high‑speed steels, which helps maintain dimensional accuracy across longer runs. For operations requiring higher surface integrity, the cutter’s capability to handle materials up to approximately 800 N/mm² in uncoated form — and higher with suitable coatings — offers clear process flexibility.

Precision slotting and secure clamping for consistent parts

Accuracy for groove depth and position is supported by the 10 mm shank and the Weldon-style driving flat that ensures positive torque transfer under higher feed forces. The tool’s cutting length 3 mm and effective length 30 mm are balanced for stable engagement in confined slots while still providing sufficient reach for stepped or recessed features. Compliance with DIN 844 Type N indicates standardised tolerances and predictable behaviour in production. The result is reduced rework and improved interchangeability of components where repeatable slot geometry is critical.

Material suitability and practical shop advantages

This cutter is optimised for steel and cast iron, where the substrate and flute geometry achieve very good results; non‑ferrous metals and stainless steels are conditionally suitable, enabling multipurpose use in mixed‑material workshops. The Weldon shank with driving flat simplifies toolholder selection and prevents slippage during interrupted cuts. For users moving from drilling to milling operations, the centre‑cut feature allows plunge starts without pre‑drilling, streamlining processes in maintenance and light production settings. The overall design supports dependable throughput and predictable tool life, making it a pragmatic choice for engineering and metalworking shops.

FAQ

What materials is this slot drill best suited for?
The TECWERK slot drill (slot cutter, SKU 2000866232NW) is very good for steel and cast iron, with conditional suitability for non‑ferrous metals and stainless steel.

Can the cutter be used for plunge drilling?
Yes, the centre‑cutting design enables plunge starts, so the cutter performs both slotting and direct plunge operations without the need for a separate drill.

What clamping style is required for reliable use?
A toolholder that accepts a Weldon shank with driving flat is recommended to ensure secure clamping and prevent slippage under higher cutting forces.

Does the cutter meet industry standards for interchangeability?
The tool conforms to DIN 844 Type N, offering standardised dimensions and tolerances for predictable performance in industrial settings.

Which feature most reduces setup time in mixed production runs?
The combination of centre‑cutting geometry and a three‑flute design reduces the need for pre‑drilling and speeds chip evacuation, lowering overall setup and cycle time.
