Keyway cutter DIN 327 Type N — D 3 mm, HSS‑Co8 (TECWERK)

The keyway cutter DIN 327 Type N is a short, three‑flute cutter designed for milling keyways and slots in steel and cast iron, combining a centre‑cutting geometry with a Weldon shank for secure tool holding

*DIN 327 Type N, three‑flute design *HSS‑Co8 high‑speed steel for heat resistance *Shank Ø 6 mm with Weldon drive flat

Precise keyway machining that reduces rework

The short, three‑edge geometry delivers controlled material removal for accurate slot profiles. Rated for materials up to 800 N/mm² with uncoated tools and up to 1000 N/mm² when coated, this cutter supports consistent tolerance achievement in batch production. Its centre‑cutting capability allows for combined face and peripheral milling, reducing the need for secondary operations and improving process efficiency. Fewer passes and reliable chip evacuation help to lower rework rates and keep cycle times predictable.

Durable cutting material and geometry for longer service life

Made from HSS‑Co8, the tool benefits from cobalt‑alloyed high‑speed steel that raises hot‑hardness and wear resistance under intermittent loads. The 3‑flute layout balances cutting engagement and chip clearance to maintain surface quality, while the right‑hand cutting orientation suits standard spindle rotation. The shank Ø 6 mm with a Weldon flat ensures a positive drive in collets or set‑screw holders, improving concentricity and minimising run‑out for repeatable cuts.

Optimised for steel and cast‑iron applications

This short cutter is particularly efficient on steel and cast iron, where rigidity and sharp cutting edges produce clean slot walls. Non‑ferrous metals and stainless steels are conditionally suitable, with performance depending on workpiece hardness and cutting parameters. The compact design reduces overhang and vibrational tendency, which contributes to a superior surface finish when producing deeper keyways. Consider a suitable coating to extend application range to higher tensile strengths where required.

Practical workshop integration and handling

The compact form and Weldon shank make this cutter straightforward to integrate into standard toolholders used in milling centres and turret mills. The combination of DIN 327 Type N geometry and HSS‑Co8 material supports reliable everyday use in production and maintenance environments. For procurement and process planning, Metav Werkzeuge offers stocking reliability and application advice to match cutter choice with the specific component requirements, helping to avoid mismatches between cutter geometry and part design.

FAQ

What is the primary application of this cutter?
The cutter is intended for keyway and slot milling, suitable for face and peripheral milling operations; the SKU 2000866176NW from TECWERK is optimised for such tasks.

Which materials is the cutter best suited to machine?
Performance is best on steel and cast iron; non‑ferrous and stainless steels are conditionally suitable depending on hardness and cutting conditions.

What does HSS‑Co8 indicate for tool performance?
HSS‑Co8 denotes high‑speed steel with around 8% cobalt, providing improved hot‑hardness and wear resistance for sustained cutting under load.

How is the cutter held in the machine?
The tool has a cylindrical shank with a Weldon drive flat (shank Ø 6 mm) for secure clamping in set‑screw holders or compatible collet systems.

Can coatings increase the cutter’s capability?
A suitable coating can raise the effective tensile strength limit to approximately 1000 N/mm² and improve tool life under demanding conditions.
