Sandvik Coromant 5752171 Tcmt Turning Insert H13A Carbide

Product Description

The SANDVIK COROMANT 5752171 is a solid carbide, uncoated turning insert in the TCMT style, part of the CoroTurn 107 series. It features a 60-degree triangular shape with a neutral hand orientation and a 7-degree relief angle (clearance code C). With an inscribed circle of 5.71 mm and a corner radius of 0.0156 inches (1/64 inch), this insert is engineered for precision turning applications. The H13A uncoated carbide grade is selected for its performance in cast iron and non-ferrous metal cutting. CNC machinists and turning center operators install this insert on compatible screw-clamped toolholders in production and job-shop environments.

This insert is primarily suited for turning cast iron and non-ferrous metals on CNC lathes and turning centers. The KM chip breaker geometry is designed to manage chip formation in these materials, helping to maintain consistent surface finish and tool life. The CoroTurn 107 series targets external turning with screw-on insert holding, making it a common choice in both production and maintenance machining applications where controlled chip evacuation is critical.

Key Features

• TCMT insert style with 60-degree triangular shape and 3 cutting edges for extended tool life
• H13A uncoated solid carbide grade optimized for cast iron (ISO K) and non-ferrous metals (ISO N)
• KM chip breaker geometry for controlled chip formation in cast iron and non-ferrous turning
• Neutral hand orientation for versatile use on standard TCMT-compatible toolholders
• Screw-held insert retention (ISO tolerance code M, clearance code C) for repeatable positioning
• ISO code TCMT 09 02 04-KM H13A for cross-reference and toolholder matching

Compatibility

Designed for use in CoroTurn 107 series screw-clamp toolholders accepting TCMT-style inserts with a 5.71 mm inscribed circle. ISO code TCMT 09 02 04-KM H13A can be used to verify compatible toolholder bore and seating requirements. Primary workpiece materials are cast iron (ISO K) and non-ferrous metals (ISO N).

Installation Notes

Installation is performed by CNC machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket before tightening the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert pocket and screw for wear or damage at each insert change to maintain accurate positioning and safe clamping.
