Sandvik Coromant 7357805 Carbide Replaceable Tip Drill 16mm

Product Description

The SANDVIK COROMANT 7357805 is a solid carbide replaceable tip drill designed for precision hole-making in metalworking applications. Built to the CoroDrill 870 series platform, this tip features a 16mm cutting diameter (0.6299 inches), a 142-degree included angle, and a PM insert geometry optimized for controlled chip formation. The TiAlN coating is applied via PVD process, delivering heat resistance and extended tool life in ferrous and hard materials. Grade 4334 carbide provides the hardness and toughness balance suited to demanding drilling operations. This tip is installed by machinists and tooling technicians working in precision manufacturing, contract machining, and production drilling environments.

This replaceable tip is intended for use in CoroDrill 870 series drill bodies with an insert seat size of 16. It is suited to CNC machining centers and turning centers performing through-hole and blind-hole drilling in steel, stainless steel, and similar workpiece materials. The replaceable tip design eliminates the need to replace the full drill body on worn tips, reducing tooling cost per hole in production environments. Coolant-through capability is not supported on this tip configuration.

Key Features

• Solid carbide tip construction for rigidity and dimensional accuracy
• TiAlN coating via PVD process for heat resistance and extended wear life
• 142-degree included angle with PM geometry for controlled chip evacuation
• Grade 4334 carbide provides toughness balance for demanding materials
• Replaceable tip design reduces tooling cost compared to solid drill replacement
• Insert seat size 16 fits CoroDrill 870 series compatible drill bodies

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 series drill bodies with an insert seat size of 16. Coolant-through drill body configurations are not compatible with this tip.

Installation Notes

Installation and replacement of carbide drill tips should be performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and all energy is isolated before changing tips. Clean the insert seat thoroughly before seating the tip to ensure proper contact and runout accuracy. Follow the drill body manufacturer torque specifications for the clamping screw to avoid tip movement or seat damage during operation.
