Kyocera TCR00270 Ceramic Turning Insert Sng Square Neutral

Product Description

The KYOCERA TCR00270 is a ceramic turning insert designed for high-speed material removal on cast iron and hard materials in CNC turning applications. It carries the SNG insert style with a square shape, a 0.5-inch inscribed circle, and a 1/16-inch (0.0625-inch) corner radius. The grade is A65 with an Al2O3 and TiC coating classification listed as uncoated, using a negative rake geometry. Insert thickness is 0.3125 inches. With 8 available cutting edges, this insert delivers extended tool life per piece. It is held in place by a clamp-style toolholder and follows both ANSI and ISO standards. Machinists and CNC operators in production and job-shop environments are the primary users.

This insert is suited for external turning, facing, boring, and chamfering operations. It performs best on cast iron and hard materials, corresponding to ISO material groups K and H, with material grades K01, K10, H01, and H10. The neutral hand orientation makes it adaptable across a range of toolholder setups. Maximum depth of cut is 0.1667 inches. Insert length is 0.5 inches, and the width is 0.5 inches (12.70 mm). The ISO code for this insert is SNGN120716T02025, and the industry standard number is SNG454T00825A65.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Before changing inserts, ensure the machine is powered down, the spindle is stopped, and all moving components are fully at rest. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the insert seat and clamp for wear or debris before seating a new insert to ensure proper contact and alignment.
