Ingersoll Cutting Tools 6322674 Turning Insert DCMT32.51

Product Description

The INGERSOLL CUTTING TOOLS 6322674 is a solid carbide turning insert in the DCMT series, designed for precision metal removal on CNC and manual lathes. It carries the ANSI code DCMT32.51FG and ISO code DCMT11T304FG, and is coated with AlTiN and TiN via a PVD process for high wear resistance. The 55-degree diamond (rhombic) insert geometry, combined with a positive rake and positive side clearance, suits finishing operations where tight tolerances and surface quality are critical. Two cutting edges are available per insert. The TT3020 grade targets stainless steel, superalloys, and titanium with a balance of high wear resistance to moderate toughness.

This insert is sized for use in DCMT-style toolholders with a screw-clamp holding method. The FG chip breaker is optimized for finishing cuts at shallow depths of cut, making it well suited for close-tolerance turning of hard-to-machine workpiece materials in aerospace, medical, and energy applications. Licensed machinists and CNC operators working with stainless steel, superalloys, and titanium will find the TT3020 grade appropriate for production and job-shop environments where tool life consistency in these demanding materials is a priority.

Key Features

• ANSI code DCMT32.51FG, ISO code DCMT11T304FG for precise toolholder matching
• AlTiN and TiN PVD coating delivers high wear resistance on stainless steel, superalloys, and titanium
• 55-degree diamond insert shape with positive rake and positive side clearance for clean finishing cuts
• FG chip breaker geometry designed for finishing operations at a maximum depth of cut of 0.079 inches
• Two cutting edges per insert for extended tool life per unit
• Screw-clamp holding method provides secure, repeatable seating in compatible toolholders

Compatibility

Designed as a direct-fit replacement for DCMT-style screw-clamp turning toolholders accepting a 3/8-inch inscribed circle insert with a 55-degree diamond shape, tolerance code M, and clearance code C. Compatible toolholders must accommodate a screw hole diameter of 0.173 inches.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine powered down and in a locked-out, tagged-out state. Use the manufacturer-specified torque driver or wrench for the clamping screw to avoid insert cracking or improper seating. Inspect the toolholder pocket and screw for wear or contamination before seating a new insert. Follow applicable shop safety protocols and machine tool manufacturer guidelines when setting cutting parameters.
