Slot drill DIN 844 Type N, Ø16 mm, HSS‑Co8 — TECWERK

The Slot drill DIN 844 Type N is a long, three‑flute, centre‑cutting tool designed for precision groove and slot milling in low to medium strength steels and cast iron.

• HSS‑Co8 three‑flute, centre‑cutting design
• Weldon cylindrical shank with drive flat
• For steels up to approx. 800 N/mm²

High‑performance geometry for reliable groove milling

The long three‑flute geometry and centre‑cutting capability deliver stable engagement in slotting operations while reducing vibration compared with fewer flutes. Manufactured from HSS‑Co8, the cutter combines toughness with heat resistance, making it well suited for interrupted cuts and applications where sudden tool engagement occurs. The tool is optimised for machining structural and mild steels, providing consistent chip evacuation and surface finish when creating narrow grooves or keyways.

Optimised dimensions for deep access and repeatable results

With an overall length of 92 mm and an effective length of 42 mm, the design enables access into deeper workpieces while maintaining rigidity at the cutting zone. The cutting length of 3 mm and a relief length of 15 mm support precise, shallow slotting where repeatable slot width is required. These dimensional characteristics reduce deflection during milling, which translates into tighter tolerances and less rework in production environments.

Secure clamping and simple tool change

The Weldon cylindrical shank with drive flat and a 16 mm shank diameter ensure positive torque transmission in standard toolholders and setscrews. This profile minimises slippage under heavy radial loads and allows fast, reliable tool changes on CNC milling machines and manual setups alike. The right‑hand cutting direction matches common machining conventions and contributes to straightforward process planning on shop floors.

Durable material suitability and practical limits

The tool is specified for machining materials of low to medium tensile strength up to approx. 800 N/mm² with the uncoated form; coating can extend capability toward 1000 N/mm² in certain applications. According to the tool design, the cutter is very well suited for steel and cast iron, while use on stainless steels and non‑ferrous metals is conditional depending on cutting data and coolant strategy. The cobalt alloy base provides enhanced red‑hardness and wear resistance, which helps to maintain cutting edges under elevated temperatures and intermittent cutting.

FAQ

What materials is the cutter best suited for?
The Slot drill DIN 844 Type N (TECWERK) is very well suited for steel and cast iron; stainless steels and non‑ferrous materials are conditionally suitable depending on cutting data.

Can the tool be used for plunge milling?
Yes, the centre‑cutting geometry allows limited plunge capability; the three‑flute design supports stable entry when using appropriate feeds.

What does the Weldon shank provide?
The Weldon cylindrical shank with drive flat on the TECWERK slot drill secures torque transmission and reduces the risk of slippage in standard set‑screw toolholders.

Is the tool available in other diameters or tolerances?
The SKU 2000866238NW refers to the Ø16 mm version; other nominal diameters and tolerance classes are available across the product family as specified by the manufacturer.

How does HSS‑Co8 benefit machining performance?
HSS‑Co8 increases red‑hardness and resistance to thermal softening, extending tool life under elevated cutting temperatures and improving performance on interrupted cuts.
