This solid carbide insert carries the PR1230 manufacturer grade with a PVD coating for extended wear resistance in steel cutting applications. The trigon (80-degree included angle) geometry features a positive rake angle and a 7-degree relief angle, promoting efficient chip evacuation and reduced cutting forces. With a 5\/16-inch inscribed circle and a 1\/8-inch thickness, this insert is sized for compact drill bodies targeting smaller-diameter bores. Installation is performed by qualified machinists and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in the KYOCERA Holeshot Drill and Coremaster Coredrill series toolholders. The M1A chipbreaker geometry is optimized for steel workpieces (ISO material group P), making it well-suited for through-hole and blind-hole drilling operations in ferrous materials. The right-hand cutting direction and positive rake design support clean entry and controlled chip flow in production and job-shop environments. A 1\/32-inch corner radius provides a balance between edge strength and surface finish at the drilled hole entrance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWCMX insert style with 80-degree trigon shape for strong, indexable cutting geometry\u003c\/li\u003e\n  \u003cli\u003ePR1230 grade solid carbide with PVD coating for wear resistance in steel applications\u003c\/li\u003e\n  \u003cli\u003eM1A chipbreaker promotes controlled chip formation and evacuation\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle and 7-degree relief angle reduce cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; 1\/32-inch corner radius for edge protection\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ANSI code WCMX050308M1A PR1230\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in the KYOCERA Holeshot Drill and Coremaster Coredrill series toolholders.
