Kyocera TCR00150 Ceramic Turning Insert SNG432 Square

Product Description

The KYOCERA TCR00150 is a ceramic turning insert in the SNG style, designed for high-speed material removal on difficult-to-machine workpieces. It carries an A65 manufacturer grade with an Al2O3 and TiC coating classification designated as uncoated, and features a negative rake geometry with a 90-degree included angle. The insert has a 0.5-inch inscribed circle, a 0.1875-inch thickness, and a 1/32-inch (0.0313-inch) corner radius. With 8 cutting edges per insert, it delivers extended tool life in demanding production turning environments. Licensed machinists and CNC operators working in job shops or production facilities are the primary users of this insert.

This insert is suited for external turning, facing, boring, and chamfering operations on cast iron and hard materials, consistent with ISO material grades K01, K10, H01, and H10. It is held by a clamp-style insert holding method and conforms to both ANSI and ISO standards. The ISO code for this insert is SNGN120408T02025 and the industry standard number is SNG432T00825A65. It is well matched to applications where ceramic cutting geometry outperforms carbide, particularly in interrupted or dry cutting conditions on hardened or abrasive workpieces.

Key Features

• SNG-style square insert with 90-degree included angle and negative rake for rigid, stable cuts
• 8 usable cutting edges per insert for cost-effective tool management
• A65 ceramic grade with Al2O3 and TiC composition suited for cast iron and hard material turning
• 0.0313-inch corner radius for controlled edge geometry on finish and semi-finish passes
• Maximum depth of cut of 0.1667 inches supports moderate stock removal
• Compatible with multi-use applications: external turning, facing, boring, and chamfering

Compatibility

Designed for use in SNG-style clamp toolholders conforming to ANSI and ISO standards. Primary workpiece materials are cast iron (ISO K) and hard materials (ISO H). Refer to KYOCERA toolholder compatibility charts for confirmed seat geometry and clamp fitment.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the correct clamp torque tool as specified by the toolholder manufacturer — do not overtighten, as ceramic inserts are brittle and susceptible to fracture from seating stress. Verify insert orientation and edge indexing before returning the machine to operation.
