Kyocera TCS61118 Ceramic Turning Insert 3/8 in Round

Product Description

The KYOCERA TCS61118 is a round ceramic turning insert designed for high-speed material removal on hard workpiece materials. It features an Al2O3 and TiC multilayer coating applied via PVD process, providing wear resistance and thermal stability during interrupted and continuous cuts. The insert carries a 3/8 inch inscribed circle, a 3/16 inch corner radius, and four usable cutting edges, making it a cost-effective choice for production turning environments. It is installed in compatible toolholders by licensed machinists and CNC operators working with hard materials classified under ISO material grade H01 and H10.

This insert is suited for external turning, facing, roll machining, and undercutting operations on hard materials. Its round geometry (Shape Code R) and full radius profile make it well matched to finishing and semi-finishing passes where consistent edge geometry matters. The neutral hand orientation allows use in both left- and right-hand toolholder setups. Industry standard number RCGX103T08015625AAA66N and ISO code RCGX090700P20015 are associated with this insert for cross-reference purposes.

Key Features

• Round insert shape with full radius and 4 cutting edges for maximum utilization
• 3/8 inch inscribed circle and 3/16 inch corner radius for consistent chip geometry
• Neutral hand orientation compatible with left- and right-hand toolholders
• Multi-use application: external turning, facing, roll machining, and undercutting
• Meets ANSI and ISO standards; clamp-style insert holding method

Compatibility

Designed for use with RCGX-style clamp-type toolholders accepting a 3/8 inch inscribed circle round insert. Compatible with ISO code RCGX090700P20015 toolholders. Intended for machining hard workpiece materials (ISO material grade H01 and H10). Verify toolholder pocket geometry and insert seat dimensions before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct clamp screw torque per the toolholder manufacturer specification and inspect the insert pocket for chips or debris before seating the new insert. Do not exceed the maximum depth of cut indicated for this insert geometry.
