TECWERK Keyway cutter DIN 327 Type N — 16 mm, HSS‑Co8, TiCN

The TECWERK keyway cutter DIN 327 Type N, 16 mm is a short, three‑flute, right‑hand cutting tool designed for milling keyways and deep slots in steel, stainless steel and cast materials

• HSS‑Co8 substrate for high toughness
• TiCN coating for extended tool life
• Weldon shank Ø16 mm for secure clamping
• Short design with centre‑cut for axial plunging

High‑performance substrate and coating for demanding cuts

Constructed from HSS‑Co8, this cutter offers improved heat resistance and toughness compared with standard HSS, making it suitable for interrupted cuts and higher temperatures. The TiCN coating reduces friction and increases surface hardness, which translates into longer tool life and more consistent dimensional results. The tool conforms to DIN 327 and is designed with a centre‑cut geometry that enables controlled axial plunging; this is especially helpful when starting a keyway or when re‑entering the workpiece.

Stable clamping and optimised geometry for reliable runs

The Weldon shank Ø16 mm provides secure clamping in standard holders, reducing slippage and run‑out during heavy engagement. With an effective length of 29 mm and an overall length of 79 mm, the cutter balances accessibility and rigidity for short overhang setups. The short flute variant and a free relief of 15 mm decrease bending moments, improving surface finish and lowering the risk of chatter when milling deeper keyways or performing peripheral passes.

Suited materials and typical applications with clear limits

This cutter is intended primarily for the machining of keyways and passfedernuten, including face and peripheral milling operations. Material suitability is high for steel, stainless steel and cast iron, while non‑ferrous metals and certain special alloys are conditionally suitable. The tool is specified for use up to approximately 800 N/mm² with an uncoated version and up to about 1000 N/mm² when the coating is employed, providing a clear performance envelope for process planning. Its right‑hand cutting orientation matches standard spindle rotations and conventional feeds.

Economic use and predictable tool life

The combination of a cobalt‑alloy substrate and TiCN coating reduces the frequency of tool changes and minimises downtime in medium‑ to high‑volume production. The short design supports stable cutting parameters and reduces the risk of premature fracturing, yielding a favourable cost‑per‑part in continuous or batch production. For operators seeking predictable results in keyway milling, this cutter offers a balance of durability and machining accuracy that supports consistent quality across workpieces.

FAQ

Which materials is this cutter best suited for?
The TECWERK keyway cutter is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable depending on the exact alloy.

Can the cutter plunge axially when starting a slot?
Yes. The centre‑cut geometry permits controlled axial plunging for establishing keyways and for re‑entry operations without pre‑drilling.

What clamping system is recommended for reliable performance?
A secure Weldon holder for a Ø16 mm shank is recommended to reduce slippage and run‑out when machining deeper keyways.

What benefits does the TiCN coating provide?
The TiCN coating on this cutter reduces friction, increases wear resistance and typically extends tool life compared with uncoated variants.
