Slotting cutter DIN 327 Type N, Ø 5 mm (HSS‑Co8) – TECWERK, short, Weldon, 3‑flute

A slotting cutter DIN 327 Type N for milling deep keyways and slots, optimised for steel and cast parts as well as controlled use in non‑ferrous and stainless materials.

• HSS‑Co8 for improved cutting strength and heat resistance
• DIN 327 Type N, short 3‑flute design
• Weldon shank with drive flat, shank Ø 6 mm

Consistent precision for demanding keyway work

The slotting cutter is manufactured to the DIN 327 Type N geometry and features HSS‑Co8 high‑cobalt steel for enhanced hardness at elevated temperatures. The Ø 5 mm cutting diameter combined with a centre‑cut point enables plunge operations and end milling without pre‑drilling, while the 3‑flute design balances chip evacuation and cutting stability. These characteristics result in reproducible slot profiles and tight tolerances when machining keyways, which supports uninterrupted production in small and medium workshops.

Clear material suitability and measurable performance gains

Designed for work on a wide range of materials, the tool is rated for machining steels up to ≈800 N/mm² with an uncoated blank and up to ≈1000 N/mm² with an appropriate coating. Casting and carbon steels are particularly well suited, while aluminium and other non‑ferrous metals can be processed under adjusted cutting parameters. The specified tensile strength limits provide a practical guide for process planning and help to avoid premature tool wear — a direct contribution to improved cost‑efficiency and fewer reworks on the shop floor.

Secure clamping and application‑focused geometry

The Weldon shank with drive flat (shank Ø 6 mm) ensures positive torque transmission in set screws or Weldon chucks, reducing slippage during heavy engagement. The short overall length increases rigidity and minimises run‑out, which is beneficial when milling deeper keyways or executing simultaneous face and peripheral cuts. Right‑hand cutting geometry and the centre‑cut capability make the tool a versatile option for both conventional and CNC milling setups, simplifying tooling choices across varied jobs.

FAQ

What materials is this cutter suitable for?
The TECWERK slotting cutter is very well suited to steel and cast iron; conditional use is possible for non‑ferrous metals and stainless materials depending on cutting data and cooling.

Can the cutter perform plunge cuts for keyways?
Yes. The centre‑cut geometry allows plunge milling as well as peripheral cutting, so the tool can produce deep keyways without mandatory pre‑drilling.

What clamping system is required for secure operation?
A Weldon chuck or set‑screw collet that accommodates the 6 mm Weldon shank and drive flat provides secure clamping and positive torque transmission.

Does coating affect performance limits?
According to the tool data, uncoated blanks are rated up to approximately 800 N/mm² tensile strength, while a suitable coating raises the limit to about 1000 N/mm², improving wear resistance under higher stresses.

Is the cutter suitable for CNC and manual milling machines?
Yes. The short 3‑flute design and rigid Weldon shank make the cutter adaptable to both CNC and manual setups, offering stable performance in both environments.
