Chamfer cutter S351TM — 21 mm diameter, 12 mm shank (Teknik Makina)

The Chamfer cutter S351TM is a shaft-mounted cutting tool designed for precision chamfering in milling operations across industrial and workshop environments.

• Precision 21 mm cutting diameter
• 12 mm shank for stable clamping
• Compatible with Korloy indexable inserts
• Single cutting edge for clean chamfers

Stable clamping for repeatable chamfers

The robust 12 mm shank and a compact 90 mm overall length combine to deliver reduced runout and improved stability during machining. With a modest mass of 0.258 kg, the tool offers predictable dynamic behaviour that helps to limit vibration and improve surface finish. The single cutting edge is optimised for producing a consistent chamfer profile with each pass, which reduces secondary operations and supports reliable downstream assembly processes.

Fast insert changes and low downtime

Changeovers are simplified by the indexable insert system that is compatible with Korloy inserts and secured by an M4x10 Torx screw. The Torx drive specification (T15) enables controlled torque application and secure seating of the insert, which reduces the risk of loosening under load. The cutter’s modular approach means worn inserts can be replaced quickly, lowering tooling costs and keeping machine uptime high.

Designed for workshop productivity and integration

As a shaft-mounted end mill category tool, the cutter integrates easily into standard milling setups where a 12 mm toolholder is available. The 40 mm cutting length provides sufficient engagement for typical chamfer depths while keeping overhang minimal. The compact design supports efficient fixturing and faster cycle times, helping to streamline batch production and minimise set-up complexity for small-to-medium runs.
