Ingersoll Cutting Tools 5518158 Cpmt Turning Insert TT5100

Product Description

The INGERSOLL CUTTING TOOLS 5518158 is a CPMT-style indexable turning insert designed for metal cutting on CNC lathes and turning centers. Built from solid carbide with a CVD-applied TiCN/Al2O3/TiN multilayer coating, this insert delivers wear resistance and thermal stability during steel machining operations. It features a diamond-shaped (C) insert geometry with an 80-degree included angle, a positive rake configuration, and a PC chip breaker. With two cutting edges and a neutral hand orientation, it suits a wide range of general turning applications on ferrous workpieces. The insert is held in place by a screw-lock method for secure, repeatable positioning.

This insert is rated for primary use on steel workpieces (ISO material code P) and is suited for finishing and light roughing passes on CNC turning equipment. The PC chip breaker geometry promotes reliable chip control at moderate depths of cut up to 0.0790 inches. The TT5100 grade with CVD coating is optimized for continuous and mildly interrupted steel cutting, making it a practical choice for production turning in job shops and manufacturing facilities. Licensed machinists and CNC operators handling steel turning work are the primary installers and users of this insert.

Key Features

• Solid carbide construction with CVD-applied TiCN/Al2O3/TiN multilayer coating for extended tool life on steel
• Diamond insert shape (80-degree included angle) with positive rake for efficient cutting action
• PC chip breaker geometry supports controlled chip evacuation at shallow to moderate depths of cut
• Two cutting edges per insert for cost efficiency in high-volume turning applications
• Screw-lock holding method ensures secure insert seating in compatible toolholders
• Neutral hand orientation allows use in a variety of turning and facing directions

Compatibility

Designed for use in CPMT-style screw-lock turning toolholders that accept a 1/4-inch inscribed circle diamond insert. ANSI code CPMT21.51PCTT5100 and ISO code CPMT060204PC TT5100 identify compatible toolholder seats.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC operator with the machine fully stopped and the spindle locked out per facility lockout/tagout procedures. Use the appropriate Torx or hex key driver specified by the toolholder manufacturer to secure the clamp screw - do not overtighten. Inspect the insert pocket seat and clamp screw condition before seating a new insert. Index to the second cutting edge only after the first edge shows wear; do not attempt to regrind solid carbide inserts.
