Sumitomo 14HB310 Milling Insert ACP300 Solid Carbide

Product Description

The SUMITOMO 14HB310 is a solid carbide coated milling insert designed for indexable milling operations in metal cutting applications. It carries the ACP300 manufacturer grade with a PVD coating process, delivering wear resistance suited to steel workpiece materials. The insert features a parallelogram shape with an AXMT style designation, an 11-degree relief angle, and a right-hand cutting orientation. At 0.138 inches thick with a maximum depth of cut of 0.394 inches and a cutting edge effective length of 0.472 inches, it is sized for precision material removal in milling tool bodies. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is intended for steel milling applications, classified under primary workpiece material code P. It is suited to production and job-shop environments where indexable milling tools require consistent edge geometry and reliable coating adhesion. The ACP300 grade with G chip breaker geometry supports controlled chip formation during face milling, shoulder milling, and similar operations on steel components. It is sold individually but requires a minimum order quantity of 10 units.

Compatibility

Designed as an OEM-style indexable milling insert for use in tool bodies that accept AXMT-style parallelogram inserts with insert size code 1235 and a thickness range of 0.125 to 0.150 inches.

Installation Notes

Indexable milling inserts are seated and secured by machinist or CNC tooling technicians using the appropriate torx or hex key for the tool body clamping screw. Power down and lock out the spindle before changing inserts. Inspect the insert pocket and seating surfaces for chips or debris before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.
