Sandvik Coromant 7357797 Replaceable Tip Drill 15.88mm

Product Description

The SANDVIK COROMANT 7357797 is a solid carbide replaceable tip drill designed for precision hole-making in metal cutting applications. It belongs to the CoroDrill 870 series and features a 15.88mm (0.6252 inch) cutting diameter with a 142-degree included angle. The tip carries a TiAlN coating applied via PVD process, which improves wear resistance and thermal stability at the cutting edge. Insert geometry is PM with an insert seat size of 15. This drill is used by machinists and tool-room professionals in production and job-shop environments where repeatable hole quality and fast tip changeout are priorities.

The CoroDrill 870 series replaceable tip design is suited for drilling operations on machining centers and CNC lathes in both light and heavy metal cutting scenarios. The 15.88mm cutting diameter fits common bore size requirements in general engineering, die and mold, and component manufacturing. Coolant-through capability is not included on this configuration, making it appropriate for external coolant or dry cutting setups where internal coolant delivery is not available.

Key Features

• Solid carbide tip construction for rigidity and wear resistance

Installation Notes

Replaceable tip drills in this series are installed and torqued using the appropriate SANDVIK COROMANT torque wrench per the toolholder manufacturer instructions — do not use substitute tools. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before tip removal or installation. Inspect the insert seat for chips or debris before seating the new tip. Follow the toolholder manufacturer guidelines for runout verification after tip replacement.
