Slot milling cutter DIN 844 Type N – TECWERK HSS‑Co8, Weldon shank, 3‑flute long

A Slot milling cutter DIN 844 Type N designed for groove and slot machining in workshops and production environments, offering centre cutting and a Weldon shank for secure toolholding.

HSS‑Co8, DIN 844 Type N
Weldon shank Ø10 mm, long 3‑flute design
For steel and cast iron up to 800 N/mm²

High‑performance material and standard compliance for reliable machining

The long, hardened HSS‑Co8 composition (cobalt alloy) provides improved red hardness and wear resistance compared with standard high‑speed steels, which means consistent cutting performance at elevated temperatures. Because the cutter conforms to DIN 844, interchangeability and predictable geometry are ensured, simplifying production planning. The centre‑cutting capability permits controlled plunging where required, while the tool’s design is optimised for machining steel and cast iron; uncoated tools are rated for workpieces up to 800 N/mm² and coated tools can extend this to about 1000 N/mm², offering a clear guide for selecting the right tool for the job.

Secure clamping and flute geometry that support process stability

A Weldon shank with a 10 mm diameter provides a direct drive interface and high‑torque transmission for demanding operations, decreasing the risk of slippage during interrupted cuts. The long, 3‑flute configuration balances cutting edge contact and chip space, improving surface finish and enabling steady feed rates. The specified relief length of 7.5 mm helps to limit contact below the cutting zone, which reduces friction and heat generation; taken together, these features support longer tool life and fewer unplanned tool changes, which benefits throughput in busy workshops.

Practical workshop applications and material suitability explained

This grooving cutter is tailored for slotting and keyway duties where dimensional reliability matters. The tool is right‑hand cutting and is described as very well suited to steel and cast iron, while suitability for stainless steel and non‑ferrous metals is conditional and depends on cutting data and coating choice. The cylindrical shank with drive flat (Weldon style) is compatible with common toolholders, enabling quick integration into existing setups. For contractors and production engineers seeking predictable performance, the cutter’s standardised dimensions and geometry reduce setup time and contribute to reproducible results across batches.
