Sandvik Coromant 5726626 Indexable Boring Bar Coroturn 107

Product Description

The SANDVIK COROMANT 5726626 is a solid carbide indexable boring bar in the CoroTurn 107 series, designed for internal boring and turning operations on CNC lathes and turning centers. It carries a minimum bore diameter of 0.5 inches (12.70 mm) and uses TCMT 21.51 inserts secured by screw clamping. The shank diameter is 0.375 inches (9.53 mm) and the overall length is 6 inches (152.40 mm). A neutral rake angle and 0-degree lead angle support consistent cutting geometry across a range of workpiece materials. Coolant-through capability helps manage heat and chip evacuation during deep boring passes. Installed by machinists and CNC tooling specialists, this bar suits both production and job-shop environments.

This boring bar is suited for internal boring and turning applications in both production machining and precision job-shop work. The C-STFC toolholder style accepts TCMT 21.51 triangular inserts, making it compatible with a broad range of insert grades for steel, stainless, cast iron, and non-ferrous materials. The right-hand cut orientation and 0.25-inch center-to-cutting-edge dimension position this bar for standard right-hand lathe setups. With multi-use capability spanning boring and turning, it reduces tooling inventory requirements for shops running varied part programs.

Key Features

• Solid carbide construction for rigidity and vibration resistance in small-bore applications
• Coolant-through design directs fluid to the cutting zone for improved tool life and chip control
• Screw clamping insert retention provides secure, repeatable insert indexing
• Neutral rake angle (0 degrees) supports versatile cutting across multiple workpiece materials
• Multi-use capability for both boring and turning reduces changeover time
• CoroTurn 107 series compatibility with TCMT 21.51 inserts, widely stocked in multiple grades and geometries

Compatibility

Designed for use with TCMT 21.51 inserts (inscribed circle 0.225 inches, insert thickness 0.094 inches). Part of the SANDVIK COROMANT CoroTurn 107 series. Suitable for CNC lathes and turning centers equipped for right-hand tooling with 0.375-inch shank bores.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before mounting or indexing inserts. Ensure the shank bore and clamping surfaces are clean and free of chips before seating the bar. Follow the machine tool manufacturer and SANDVIK COROMANT tooling assembly guidelines for proper insert torque and coolant-through connection.
