Value Collection TCN54490D Milling Insert CTA4-3/32

Product Description

The VALUE COLLECTION TCN54490D is a solid carbide milling insert designed for precision metal removal in milling operations. Manufactured to the CTA4-3/32 ISO code, this insert features a titanium nitride (TiN) coating over a C5-grade solid carbide substrate, delivering improved wear resistance and extended tool life at elevated cutting speeds. The insert is 3/16 inches thick with an inscribed circle diameter of 0.4600 inches and a corner radius of 3/32 inches. It is installed and changed out by machinists and toolroom technicians on milling cutters used in production and job-shop environments.

This insert is suited for milling steel, cast iron, and similar workpiece materials where a C5-grade carbide with TiN coating provides an effective balance of hardness and toughness. The CTA4-3/32 geometry fits indexable milling cutter bodies designed to accept CTA4-style inserts. Typical applications include face milling, shoulder milling, and profile milling on manual or CNC machining centers in both light-duty and moderate-production settings. This insert is sold individually and is subject to a minimum order quantity of 10 pieces per order.

Key Features

• Solid carbide construction with C5 material grade for high hardness and wear resistance
• TiN coating reduces friction and extends insert life at higher cutting speeds
• CTA4-3/32 ISO geometry with a 3/32-inch corner radius for controlled cutting edge engagement
• Inscribed circle diameter of 0.4600 inches, falling within the 0.4000 to 0.5000 inch range for CTA4-style seats
• 3/16-inch insert thickness provides rigidity and resistance to breakage under interrupted cuts

Compatibility

Designed for use in indexable milling cutter bodies that accept CTA4-style inserts with an inscribed circle range of 0.4000 to 0.5000 inches and a 3/32-inch corner radius seat configuration.

Installation Notes

Installation is performed by a machinist or toolroom technician. Always power down and lock out the machining center spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the cutter body manufacturer when seating the insert — do not overtighten by hand. Inspect the pocket seating surface for chips or debris before installing a new insert to ensure proper seating and prevent premature edge failure.
