Sandvik Coromant 7357849 Carbide Replaceable Tip Drill 17mm

Product Description

The SANDVIK COROMANT 7357849 is a solid carbide replaceable tip drill designed for precision hole-making in metalworking and machining applications. Built to the CoroDrill 870 series standard, this tip features a 17mm cutting diameter (0.6693 inches) and an MM insert geometry. The cutting surface carries an AlTiCrN coating applied via PVD process, providing thermal resistance and wear protection during demanding drilling operations. The 142-degree included angle supports stable entry and consistent chip formation. It is installed by machinists and tooling technicians as a replaceable cutting tip on compatible CoroDrill 870 drill bodies.

This replaceable tip is suited for production machining environments where tool changeover speed and consistent bore quality are priorities. The 17mm seat size matches dedicated CoroDrill 870 drill body holders. Typical applications include medium-to-high volume drilling in steel, stainless steel, and cast iron workpieces in both job shop and production floor settings. The PVD AlTiCrN coating extends tool life in dry or minimum quantity lubrication conditions. Coolant-through capability is not supported on this tip configuration.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. The drill body must be fully removed from the spindle and secured before seating or removing the replaceable tip. Use only the recommended torque wrench and tip seat tool supplied or specified by SANDVIK COROMANT for this series — do not use improvised tooling to seat or unseat the tip. Inspect the insert seat for chips, debris, or wear before installing a new tip.
