Keyway milling cutter DIN 327 Type N, 20 mm – HSS‑Co8, Weldon shank | TECWERK

The Keyway milling cutter DIN 327 Type N, 20 mm is a short, three‑flute, centre‑cutting slot cutter designed for face and peripheral milling of deep keyways in a range of engineering materials.

• HSS‑Co8 construction for heat resistance
• DIN 327 Type N geometry
• Weldon shank with drive flat
• Three‑flute, centre‑cutting design

High‑performance geometry for repeatable results

The cutter combines a hardened HSS‑Co8 substrate with the standardised DIN 327 profile to deliver reliable shape control and tool life in demanding milling tasks. The 20 mm diameter and three‑flute design balance chip evacuation and cutting stability, while the centre‑cutting capability enables plunge starts and safe face milling. These characteristics reduce cycle time variance and help maintain tight tolerances on components produced in series.

Material suitability and practical limits explained

This short slot cutter is very well suited to steel and cast iron, offering efficient cutting action where robustness is required. With an uncoated tool, workpieces up to 800 N/mm² tensile strength can be machined; using a coated variant extends that range to approximately 1000 N/mm². Non‑ferrous alloys and stainless steels are conditionally suitable, enabling selective use in mixed‑material batches when cutting data is adjusted accordingly.

Secure clamping and handling for shopfloor efficiency

A Weldon shank with a drive flat provides positive torque transfer and simple axial location in milling holders, while the 20 mm shank diameter ensures compatibility with common toolholders. The tool’s 19 mm free cutting length is optimised for deep keyways without unnecessary overhang, improving rigidity and reducing vibration on shorter setups. These mechanical details support predictable changeover times and safer high‑feed operations.

Application focus and benefits for production workshops

Designed for milling deeper keyways, both for face and peripheral operations, the short configuration of this cutter delivers compact handling and improved chatter resistance compared with long versions. The three‑cutting‑edge geometry promotes steady chip breakage and lowers the risk of built‑up edge on interrupted cuts. For workshop managers this translates into fewer rejects, simplified tool inventory and more consistent throughput on shaft and hub assemblies.

FAQ

Which materials are best machined with this cutter?
The TECWERK keyway milling cutter is very well suited to steel and cast iron; non‑ferrous metals and stainless steels are conditionally suitable depending on cutting data.

Can the cutter start a plunge cut or must it be ramped?
Yes — the centre‑cutting geometry allows plunge starts, so the tool can be used for face milling and plunging when set up correctly with the recommended holders.

What does HSS‑Co8 mean for tool life and cutting speed?
HSS‑Co8 denotes high‑speed steel with 8% cobalt, which improves red‑hardness and wear resistance; the material provides a reliable compromise between toughness and high‑temperature hardness for general engineering applications.

Is the Weldon shank compatible with standard toolholders?
The Weldon shank with drive flat is compatible with collet chucks and Weldon‑type holders that accept a 20 mm shank, ensuring secure torque transmission during peripheral and face milling.

What is the SKU for ordering or referencing technical data?
Reference SKU 2000866196NW for this short DIN 327 Type N keyway milling cutter when enquiring or ordering.
