Sandvik Coromant 7357676 Replaceable Tip Drill 13mm

Product Description

The SANDVIK COROMANT 7357676 is a replaceable-tip carbide drill designed for precision hole-making in metalworking applications. Built to CoroDrill 870 series specifications, it features a 13mm (0.5118 inch) cutting diameter with a 142-degree included angle. The tip is manufactured from solid carbide with grade 4334 and carries a TiAlN coating applied via PVD process, delivering hardness and heat resistance suited to demanding production drilling. This drill is installed by machinists and tooling technicians operating CNC machining centers and production drilling equipment.

The 7357676 fits within the CoroDrill 870 replaceable-tip system, which uses a standardized insert seat size 12 interface. It is suited for short-hole drilling operations in ferrous and non-ferrous metals in both job shop and production environments. The PM insert geometry supports stable cutting action across a range of workpiece materials. This drill does not include through-coolant capability, so external coolant or flood cooling is the appropriate method for chip evacuation and heat management during use.

Compatibility

Designed for use with compatible SANDVIK COROMANT CoroDrill 870 series drill bodies accepting insert seat size 12. Consult the CoroDrill 870 system tooling guide to confirm body compatibility before ordering.

Installation Notes

Installation and replacement of carbide drill tips should be performed by a qualified machinist or tooling technician with the machine fully powered down and locked out per facility lockout/tagout procedures. Use the correct torque tool and insert key specified for the CoroDrill 870 system to seat the tip properly — do not over-tighten or substitute tools. Inspect the insert seat for debris or damage before mounting a new tip. Confirm runout and tool projection before returning the spindle to operation.
