Kennametal 4053336 Turning Insert TDHB12807505 KCU10 Carbide

Product Description

The KENNAMETAL 4053336 is a solid carbide turning insert carrying the TDHB12807505 geometry in the KCU10 grade. It features a Physical Vapor Deposition (PVD) TiAlN coating and a 60-degree triangular profile with three usable cutting edges. The inscribed circle measures 0.1600 inches and the corner radius is 0.0079 inches (1/128 inch). A 15-degree relief angle combined with a positive rake and flat-top chipbreaker geometry supports efficient chip control in interrupted and continuous turning operations. Licensed machinists, CNC operators, and toolroom technicians install this insert in screw-on toolholders for precision metal removal.

This insert is suited for turning steel, stainless steel, superalloys, and titanium workpieces — ISO material codes P, M, and S. Its screw-on holding method and neutral hand orientation make it compatible with a range of standard indexable turning toolholders. Maximum depth of cut reaches 0.0923 inches, making it appropriate for medium finishing and light roughing passes. It is sold with a minimum order quantity of 5 pieces per order.

Key Features

• KCU10 grade solid carbide with PVD TiAlN coating for heat and wear resistance on difficult-to-machine alloys
• 60-degree triangle insert shape (TDHB geometry) with 3 indexable cutting edges
• 0.0079-inch corner radius for controlled surface finish in finishing and semi-finishing cuts
• 15-degree relief angle with positive rake and flat-top chipbreaker for reduced cutting forces
• Screw-on holding method for secure, repeatable seating in compatible toolholders
• Meets ANSI and ISO standards; ISO code TDHB07T1202

Compatibility

Designed for use in screw-on style indexable turning toolholders accepting TDHB-geometry triangular inserts with a 0.0950-inch hole diameter. Primary workpiece materials are steel, stainless steel, superalloys, and titanium per ISO material codes P, M, and S.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not over-tighten the clamping screw, as this can fracture the carbide substrate. Inspect the insert pocket seating surface and shim for wear or debris before seating a new edge.
