Kyocera TKZ00620 Turning Insert Dcmt 55 Diamond Cermet PV90

Product Description

The KYOCERA TKZ00620 is a DCMT-style cermet turning insert with a TiN coating and PV90 manufacturer grade, designed for precision metal cutting on CNC lathes and turning centers. It features a 55-degree diamond insert shape, a positive rake angle of 15 degrees, and a honed cutting edge style that promotes clean chip formation and extended tool life. The insert measures 0.914 inches in length with a 0.375-inch inscribed circle and a corner radius of 0.008 inches. It is held in place via screw clamping and suits external turning, copying, and back boring operations. Licensed machinists and CNC operators are the primary installers of this insert type.

This insert is suited for turning steel and stainless steel workpiece materials, corresponding to ISO material codes P and M, and material grades P01, P10, P20, M01, M10, and M20. Typical applications include external turning, profile copying, and back boring on light-to-medium-duty cuts. The neutral hand orientation makes it compatible with standard right-hand toolholders configured for DCMT geometry. It is sold individually per package with a minimum order quantity of 10 units.

Key Features

• 55-degree diamond insert shape (DCMT style) with positive rake angle for reduced cutting forces on steel and stainless steel
• PV90 cermet grade with TiN coating for wear resistance at elevated cutting speeds
• Honed cutting edge style promotes consistent surface finish and reduces built-up edge
• Two cutting edges per insert extend usable tool life
• HQ chip breaker geometry supports external turning, copying, and back boring operations
• Screw-clamp holding method ensures rigid, repeatable seating in compatible toolholders

Compatibility

Designed for use in screw-clamp toolholders accepting DCMT insert geometry with a neutral hand orientation. ISO code DCMT11T302HQ and industry standard number DCMT32505HQPV90 apply. Conforms to ANSI and ISO standards for indexable turning inserts.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before indexing or replacing the insert. Use the correct torx or hex key for the clamping screw and do not overtighten, as excess torque can crack the insert or damage the toolholder pocket. Inspect the insert seat and shim for debris or wear before seating a new insert.
