TECWERK Slot Drill DIN 844 Type N — 20 mm, HSS‑Co8, TiCN, 3‑flute, Weldon shank

The TECWERK Slot Drill DIN 844 Type N is a long, centre‑cutting slotting cutter designed for milling grooves and slots in steels, stainless steel and cast iron where repeatable, high‑quality results are required

• HSS‑Co8 high‑cobalt construction
• TiCN coating for extended tool life
• Weldon shank for secure clamping
• Centre‑cut, 3‑flute long design

Reliable cutting performance for steels and stainless materials

The long, centre‑cutting design provides dependable entry into the workpiece, enabling axial plunging as well as conventional slot milling. Manufactured from HSS‑Co8, the tool retains hardness under thermal load and offers very good suitability for steel and inox, as specified to DIN 844. The 3‑flute geometry balances cutting forces and chip evacuation, which supports stable machining when producing grooves or keyways in medium‑strength materials. Where a coated tool is used, the cutter handles higher tensile strengths compared with an uncoated variant, increasing usable application range while keeping results consistent.

Durable coating and secure tool holding for uninterrupted runs

The TiCN coating reduces friction and improves wear resistance, resulting in longer tool life and fewer tool changes in repetitive production. Combined with the Weldon shank, the cutter delivers improved clamping stability for demanding cycle work, reducing vibration and the risk of runout. The long version with a 20 mm nominal diameter and a 20 mm shank guarantees compatibility with standard toolholders while the free relief (19 mm) and effective length (52 mm) provide a balanced engagement for prolonged operations. These characteristics support consistent part quality and reduced machine downtime.

Practical application notes and operational benefits

The cutter conforms to DIN 844 Type N and is engineered for slots and grooves in a range of materials: very good suitability for steel, stainless steel and cast iron, and conditional suitability for non‑ferrous alloys and special alloys. The tool is right‑hand cutting and features a short cutting length of 3 mm, allowing precise local machining. For process planning, consider the coated variant where increased tensile strength of the workpiece is expected; batch production benefits from the improved wear resistance and the secure Weldon clamping. For further specification matching and recommended cutting parameters, technical consultation is available to ensure the chosen cutter fits the machining strategy.

FAQ

What materials is this slot drill best suited for?
The TECWERK slot drill (DIN 844 Type N, SKU 2000866264NW) is very well suited for steel, stainless steel and cast iron, with conditional suitability for certain non‑ferrous and special alloy applications.

Does the TiCN coating improve performance on harder materials?
Yes. The TiCN coating enhances wear resistance and allows the coated cutter to handle higher tensile strengths compared with the uncoated version, extending service life under tougher conditions.

What clamping system is recommended for this cutter?
Use a toolholder that accepts a 20 mm Weldon shank to ensure secure clamping and minimised runout during slot milling with this long, 3‑flute cutter.

Can the cutter plunge axially or is it only for side milling?
The centre‑cutting geometry permits axial plunging as well as conventional slotting, enabling flexible use in groove and keyway operations.

Is this cutter compliant with industry standards?
The cutter is made to DIN 844 Type N specifications and is designed for repeatable industrial use in accordance with those norms.
