Accupro 75333104 Dcgt Carbide Turning Insert 55 Degree

Product Description

The ACCUPRO 75333104 is a carbide turning insert designed for precision metal cutting on CNC and manual lathes. Styled to the DCGT geometry, it features a 55-degree diamond (rhombic) shape, a positive side clearance, and a polished coating finish that reduces built-up edge during finishing passes. The insert carries ANSI code DCGT21.51 and ISO code DCGT070204, with a corner radius of 0.0157 inches (0.40 mm) suited for fine finishing work. It is held in place by a screw-clamp toolholder and provides two usable cutting edges per insert. Grade ACN15K targets cast iron and non-ferrous materials, balancing high wear resistance with moderate toughness.

This insert is used in turning applications on cast iron, aluminum, and other non-ferrous workpieces in both production and job-shop environments. The LMF+ chip breaker geometry is optimized for light-to-medium finishing cuts, making it appropriate for tight-tolerance work where surface finish and dimensional accuracy are priorities. Machinists and CNC operators in metalworking shops are the primary users. The maximum depth of cut is 0.0531 inches (1.35 mm), keeping this insert in its intended finishing range.

Key Features

• DCGT diamond (rhombic) 55-degree insert shape for positive-rake finishing geometry
• Grade ACN15K carbide with polished finish for cast iron and non-ferrous applications
• LMF+ chip breaker optimized for light-to-medium finishing cuts
• Two cutting edges per insert for extended tool life per unit cost
• Screw-clamp holding method for secure, repeatable seating in compatible toolholders
• Positive side clearance (C clearance code) reduces cutting forces on thin-wall and delicate workpieces

Compatibility

Designed for use in screw-clamp DCGT-style toolholders accepting inserts with ANSI code DCGT21.51 and ISO code DCGT070204, with an inscribed circle of 0.2500 inches and a hole diameter of 0.1114 inches.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC operator with the machine powered down and all axes locked. Use the appropriate torx or hex key to torque the clamp screw to the toolholder manufacturer's specified value — do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Follow your facility's lockout/tagout procedure before any tooling change.
