Sandvik Coromant 7358014 Carbide Replaceable Tip Drill 20.64mm

Product Description

The SANDVIK COROMANT 7358014 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 20.64 mm (0.8126 inch) cutting diameter with a 142-degree included angle. The tip carries a TiAlN coating applied via PVD process, using the PM insert geometry and manufacturer grade 4334. This drill is used by machinists and tooling professionals in CNC turning centers and machining centers where repeatable, close-tolerance drilling is required. The replaceable tip design reduces tooling cost by allowing tip exchange without discarding the drill body.

The CoroDrill 870 series is suited for general-purpose drilling in steel, stainless steel, and cast iron. The 20.64 mm diameter targets applications requiring precision bores in production and job-shop environments. Insert seat size 20 matches the corresponding CoroDrill 870 drill body. This tip does not include coolant-through capability, making it appropriate for setups where through-spindle coolant is not available or not required. Licensed machinists and CNC operators performing production drilling operations are the primary installers of this component.

Key Features

Compatibility

Designed for use with CoroDrill 870 series drill bodies accepting insert seat size 20. Consult the SANDVIK COROMANT CoroDrill 870 product line documentation to confirm body compatibility before ordering.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the replaceable tip. Use the appropriate Torx or drive key specified by the tool body manufacturer to secure the tip — do not improvise with substitute drivers. Verify tip seating and runout with a dial indicator before resuming production cuts.
