Sandvik Coromant 7357893 Replaceable Drill Tip 18mm

Product Description

The SANDVIK COROMANT 7357893 is a replaceable drill tip designed for the CoroDrill 870 modular drilling system. It features an 18.00 mm (0.7087 inch) cutting diameter with a 142-degree point angle and is manufactured from solid carbide with a fine grain material grade. The AlTiCrN coating is applied via a PVD process, delivering heat and wear resistance suited to demanding cutting conditions. This tip uses a clamp-style insert holding method with a seat size of 18, and is intended for solid drilling applications where repeatable tip replacement reduces downtime and tooling cost.

This drill tip is engineered for machining stainless steel, superalloys, and titanium — material codes M and S — making it appropriate for aerospace, medical, energy, and general precision manufacturing environments. It is used in CNC machining centers where the CoroDrill 870 body is already mounted. The helical, regular spiral flute configuration with two flutes provides controlled chip evacuation during through-hole and blind-hole solid drilling operations. Coolant-through capability is not supported on this tip.

Key Features

• 18.00 mm cutting diameter with 142-degree standard point angle for accurate entry and reduced thrust force
• Solid carbide fine grain substrate for rigidity and edge integrity in tough workpiece materials
• AlTiCrN PVD coating for high-temperature wear resistance when cutting stainless steel, superalloys, and titanium
• Two helical flutes with regular spiral for consistent chip flow in solid drilling operations
• Clamp-type insert holding with seat size 18 for secure, repeatable tip indexing on CoroDrill 870 bodies
• ISO number 870-1800-18-MM 2334 for straightforward cross-reference and ordering

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 series modular drill bodies accepting insert seat size 18. Refer to the CoroDrill 870 program documentation to confirm body-to-tip compatibility before installation.

Installation Notes

Installation is performed by machining professionals in a CNC toolroom or setup environment. The machine spindle must be fully stopped and the tool assembly secured before tip removal or installation. Use the correct clamping key or torx driver specified for the CoroDrill 870 seat to avoid seat damage — do not use improvised tooling. Inspect the insert seat for debris or damage before seating the new tip to ensure proper contact and runout performance.
