Sandvik Coromant 7357635 Replaceable Tip Drill 12mm Carbide

Product Description

The SANDVIK COROMANT 7357635 is a carbide replaceable tip drill insert designed for use in the CoroDrill 870 drill body system. The tip is manufactured from solid carbide in grade 4334 and features a TiAlN coating applied via a PVD process, providing wear resistance and thermal stability during high-speed drilling operations. The insert geometry is PM with an included angle of 142 degrees and a cutting diameter of 12.00 mm (0.4724 inches). This tip is installed and replaced by machinists and tool-room technicians as part of a modular indexable drilling setup, reducing downtime compared to regrinding solid drills.

This replaceable tip is intended for use in compatible CoroDrill 870 drill bodies with an insert seat size of 10. It is suited for ferrous and non-ferrous machining applications in production environments where consistent hole geometry and repeatable tool life are required. The modular design allows the drill body to be retained while only the carbide tip is replaced at wear-out, making it practical for high-volume drilling operations in shops running CNC machining centers or lathes with live tooling.

Key Features

• Solid carbide grade 4334 tip for wear resistance in demanding drilling applications
• TiAlN coating via PVD process for thermal stability and extended tool life
• 12.00 mm cutting diameter (0.4724 inches) with PM insert geometry
• 142-degree included angle for controlled entry and reduced thrust force
• Insert seat size 10 for use in compatible CoroDrill 870 drill bodies
• Replaceable tip design reduces tooling cost by reusing the drill body

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 series drill bodies with an insert seat size of 10. Refer to the CoroDrill 870 system documentation to confirm body compatibility before ordering.

Installation Notes

Installation is performed by a machinist or tooling technician. The drill body must be removed from the spindle and the machine powered down before tip exchange. Use the manufacturer-specified torx or clamping key to seat and secure the tip according to the tool body design. Verify tip seating and runout before resuming cutting operations.
