TECWERK Long Slot Milling Cutter DIN 844, Ø18 mm – HSS‑Co8, TiCN, Weldon Shank

The TECWERK Long Slot Milling Cutter DIN 844 is a centre‑cutting, three‑flute slot cutter designed for precision grooving and slotting in steel, stainless steel and cast iron across demanding workshop and industrial environments

• HSS‑Co8 high‑cobalt substrate for durability
• TiCN coating for extended tool life
• Weldon shank with drive flat for secure clamping
• Centre‑cutting, three‑flute geometry for precise slots

Engineered for consistent slot machining and long tool life

This long slot cutter uses a HSS‑Co8 high‑cobalt substrate combined with a TiCN surface treatment to improve wear resistance and heat tolerance. The three‑flute, centre‑cutting geometry delivers balanced chip evacuation and the ability to plunge where required, while the long version increases reach for deeper grooves. These technical choices reduce tool changes and support steady production flow, making the cutter suitable for repetitive slotting tasks with stable results.

Material compatibility and reliable cutting performance

The cutter is specified for machining a wide range of materials: steel, stainless steel (INOX) and cast iron are very well suited, while non‑ferrous metals and special alloys are conditionally suitable. Performance guidance notes the tool can handle workpiece strengths of approximately 800 N/mm² with an uncoated tool and up to 1000 N/mm² when the cutter is TiCN‑coated, which translates into dependable performance across typical workshop steels and many hardened components. The specification helps planners select feeds and speeds that balance removal rate and tool life.

Practical shank design and workshop handling advantages

A 16 mm shank with a Weldon drive flat (cylindrical shank with drive flat) ensures fast, repeatable clamping and reduced slippage in toolholders, while the free cutting length of 15 mm and the long body provide access to deeper slots without sacrificing stiffness. The cutter’s right‑hand cutting direction and DIN‑compliant design (DIN 844 Type N) simplify integration into CNC programmes and manual milling operations, lowering setup time and improving process reliability in small batches and continuous production alike.

Economic and operational benefits for precision workshops

By combining a robust substrate, a hard TiCN coating and a secure shank interface, the cutter offers a favourable cost‑benefit ratio through extended service intervals and predictable performance. The standardised tolerances (nominal diameters with e8 tolerance for sizes beyond 15 mm) support consistent slot dimensions and fitment. For procurement and operations teams this means fewer tool replacements, steadier cycle times and reduced scrap rates, which together contribute to smoother production logistics.
