Carmex 16ER/IL0.077BXC Grooving Insert Solid Carbide Tin

Product Description

The CARMEX 16ER/IL0.077BXC is a solid carbide grooving insert engineered for precision turning and grooving operations on CNC lathes and turning centers. Manufactured to ISO standards, this insert features a PVD-applied TiN coating over a C6-grade solid carbide substrate, delivering wear resistance suited to interrupted and continuous cuts. The cutting width measures 0.077 inches, with a maximum depth of cut reaching 0.079 inches. The positive rake geometry at 15 degrees reduces cutting forces and heat generation at the tool-workpiece interface. Machinists and CNC operators working in production and job-shop environments install this insert as part of Series 16 grooving toolholders.

This insert is designed for grooving and profiling operations in cast iron and steel workpieces. The left-hand and right-hand capability makes it adaptable to both external and internal grooving setups. With an inscribed circle of 3/8 inch and a hole diameter of 0.157 inches, it seats securely in compatible Series 16 toolholders. The 0.004-inch corner radius and 10-degree external relief angle support clean groove walls and accurate dimensional control in production turning applications.

Compatibility

Designed for use with Series 16 grooving toolholders accepting a 3/8 inch inscribed circle insert with a 0.157 inch hole diameter. Suitable for primary workpiece materials classified as cast iron (ISO K) and steel (ISO P).

Installation Notes

Installation is performed by CNC machinists and qualified turning center operators. Power down and lock out the machine spindle before seating or removing the insert. Use a calibrated torque wrench and the toolholder manufacturer's specified clamping hardware to secure the insert - do not over-torque the clamping screw. Verify insert seating and edge condition visually before resuming cutting operations.
