Sandvik Coromant 5752116 Turning Insert Carbide Triangle

Product Description

The SANDVIK COROMANT 5752116 is a solid carbide, uncoated turning insert in the CoroTurn 107 series, designed for precision turning operations on hard materials. Manufactured to ISO grade 7025, this insert carries the TCGW21.52S0320F designation, indicating a triangular shape with a 60-degree included angle, a 7-degree relief angle (clearance code C), and a G-tolerance class for tight dimensional control. It features a 1/4-inch (0.2500-inch) inscribed circle, a 1/32-inch (0.0313-inch) corner radius, and a W-type chip breaker geometry. The insert is held in place by a screw (hole diameter 0.1102 inches) and is intended for use by machinists and CNC operators working with hard workpiece materials.

This insert fits CoroTurn 107 series toolholders and is suited for finish and semi-finish turning of hard materials in both production and job-shop environments. Its neutral hand orientation means it is compatible with both right-hand and left-hand turning applications. The 60-degree triangular shape provides three usable cutting edges per insert, making it an efficient choice for high-volume turning operations. Typical applications include turning hardened steels and other hard-to-machine materials where dimensional accuracy and surface finish are critical.

Key Features

• Solid carbide construction, uncoated (bright finish) for hard-material turning
• ISO manufacturer grade 7025 for consistent cutting performance
• Three cutting edges per insert due to 60-degree triangular shape
• W-type chip breaker geometry for controlled chip evacuation
• Screw-clamp holding method for secure, repeatable seating in the toolholder
• G-tolerance class for precise insert-to-insert dimensional consistency

Compatibility

Designed for use with CoroTurn 107 series toolholders that accept TCGW-style triangular inserts with a 1/4-inch inscribed circle and screw-clamp mounting. ISO designation TCGW110208S01020F 7025 may be referenced when cross-referencing to compatible toolholder seats.

Installation Notes

Insert replacement and seating should be performed by a qualified machinist or CNC technician with the machine powered down and all axes secured. The insert pocket and clamping screw should be cleaned before seating the new insert to ensure proper contact and torque. Follow the toolholder manufacturer's guidelines for clamping screw procedure. Handle carbide inserts carefully to avoid chipping the cutting edges prior to use.
