Kennametal 5667479 Turning Insert SP4019 Carbide 55 Deg

Product Description

The KENNAMETAL 5667479 is a DCGT-style carbide turning insert designed for precision finishing and light interrupted cuts on ferrous and non-ferrous workpiece materials. Manufactured to the ANSI insert code DCGT32.50.5 and ISO code DCGT11T302, this insert features a 55-degree diamond (rhombic) shape with a positive side clearance angle of 7 degrees. The SP4019 grade carbide substrate is engineered to deliver consistent edge life and dimensional accuracy in turning applications. The 62 chip breaker geometry promotes effective chip control during finish turning passes.

This insert is suited for CNC turning centers and manual lathes in both production and job-shop environments. It is typically used in finish turning and light roughing operations where tight tolerances and superior surface finish are required. The screw-holding method secures the insert firmly in compatible DCGT toolholders. Machinists and toolroom technicians working with aluminum, brass, and similar materials will find the geometry and grade combination well-matched to those applications.

Key Features

• DCGT 55-degree diamond shape with positive clearance for reduced cutting forces
• SP4019 carbide grade for consistent performance in finish turning
• 62 chip breaker geometry for controlled chip evacuation
• Screw-mount holding method for secure insert retention
• Corner radius of 0.1250 inches for surface finish consistency
• Inscribed circle of 0.3750 inches indicating insert cutting diameter coverage

Compatibility

Designed as an OEM-style replacement for DCGT-style turning insert toolholders accepting the ANSI insert code DCGT32.50.5 or ISO code DCGT11T302 with screw-clamping retention.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician with the machine at a complete stop and all power isolated. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specification without overtightening. Inspect the insert pocket and seating surface for chips or debris before installing a new insert. Verify insert orientation and chip breaker direction relative to the intended cut before resuming operation.
