Accupro 75511337 Tcmt Turning Insert Carbide Cvd

Product Description

The ACCUPRO 75511337 is a TCMT-style carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. Featuring a triangular insert shape with a 60-degree included angle, this insert carries a CVD coating under the ACK20P manufacturer grade, delivering high wear resistance on steel and cast iron workpieces. The corner radius measures 0.0157 inches (0.40 mm), and the insert provides 3 usable cutting edges per insert with a neutral hand orientation. A WM+ chip breaker geometry and positive side clearance contribute to controlled chip flow and stable performance across a range of turning conditions.

This insert is suited for finish to medium turning applications in both job shop and production environments. The ACK20P grade with CVD coating is targeted at Primary Workpiece Material Codes P (steel, high wear resistance) and K (cast iron, high wear resistance to moderate toughness). Maximum depth of cut is 3.00 mm (0.1181 inches). The insert is held by screw clamping and conforms to ANSI Insert Code TCMT21.51 and ISO Insert Code TCMT110204, making it a direct fit in compatible TCMT toolholders. Sold individually; minimum order quantity is 10 pieces.

Compatibility

Designed to fit TCMT-style screw-clamp turning toolholders conforming to ANSI size code 21.51 and ISO size code 110204. Compatible with toolholders accepting a 0.2500-inch (6.35 mm) inscribed circle TCMT insert.

Installation Notes

Installation of turning inserts should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key driver to seat the clamping screw; do not overtighten by hand without a calibrated tool. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert to ensure proper contact and runout control.
