Sandvik Coromant 5758092 Laydown Threading Insert 1125

Product Description

The SANDVIK COROMANT 5758092 is a solid carbide laydown threading insert from the CoroThread 266 series, designed for right-hand internal 60-degree V-thread cutting. Coated with a dual PVD finish of TiAlN and TiCrAlN, it handles a thread pitch range of 3.50 to 6.00 mm (4 to 7 TPI), making it suitable for a wide range of internal threading operations. The insert features a 1/2-inch (12.70 mm) inscribed circle and a thickness of 0.2190 inches (5.56 mm). It is intended for use by machinists and tooling professionals in CNC turning and threading applications.

This insert is used in internal threading operations on CNC lathes and turning centers where precision thread form and tool life are critical. The 1125 manufacturer grade and PVD coating are well suited for threading a range of workpiece materials in both production and job-shop environments. The A chipbreaker geometry supports clean chip evacuation in through-hole and blind-hole threading scenarios. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe indexed position before changing inserts. Use the correct torx or insert-clamping wrench specified for the CoroThread 266 toolholder to secure the insert without overtightening. Inspect the insert seat and clamping screw for wear or debris before seating the new insert.
