Accupro 75355297 DCGT070201 Carbide Turning Insert

Product Description

The ACCUPRO 75355297 is a DCGT-style carbide turning insert designed for precision metal cutting operations on CNC lathes and turning centers. Cataloged under ISO code DCGT070201, this insert features a diamond (rhombic) 55-degree included angle, a 7-degree relief angle, and a polished coating finish that supports tight-tolerance finishing passes. The corner radius measures 0.0039 inches (0.10 mm), making it well-suited for fine finishing work where surface finish and dimensional accuracy are critical. The LMF+ chip breaker geometry promotes efficient chip control during light to moderate cuts. Installed using a screw-holding method, the insert seats securely in compatible DCGT toolholders used in production and job-shop turning applications.

This insert is intended for turning cast iron and non-ferrous materials, including aluminum alloys. The ACN15K grade delivers high wear resistance with moderate toughness, covering ISO material groups K (cast iron) and N (aluminum and non-ferrous). It is a neutral-hand insert, allowing use in both conventional and back-turning setups. The maximum depth of cut is 0.0531 inches (1.35 mm), positioning this insert for finishing and semi-finishing passes rather than heavy roughing. Machinists, CNC operators, and toolroom technicians working in production environments are the primary users of this insert type.

Key Features

• ISO code DCGT070201 with ANSI code DCGT21.500 for cross-reference compatibility
• Diamond 55-degree insert shape (D) with 7-degree positive side clearance for reduced cutting forces
• ACN15K carbide grade rated for cast iron (K) and aluminum and non-ferrous (N) workpiece materials
• LMF+ chip breaker geometry designed for light finishing and semi-finishing cuts
• Polished coating finish supports smooth surface finish on non-ferrous and cast iron workpieces
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

Designed as an OEM-style replacement turning insert for DCGT-style screw-lock toolholders accepting inserts with an inscribed circle of 0.2500 inches (6.35 mm), a tolerance code of G, and a clearance code of C per ANSI and ISO standards.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key for the screw-clamp seat to secure the insert without over-torquing the clamping screw. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure proper support and prevent premature edge failure.
