Sandvik Coromant 7357713 Replaceable Tip Drill 14mm

Product Description

The SANDVIK COROMANT 7357713 is a carbide replaceable tip drill designed for precision hole-making in metalworking and machining applications. Built on the CoroDrill 870 platform, this drill accepts a solid carbide tip with a GP insert geometry and a 152-degree included angle, delivering controlled cutting action at the entry point. The tip carries a TiAlN coating applied via PVD process, which improves heat resistance and extends tool life in demanding cutting conditions. At 14mm (0.5512 inches) cutting diameter and a weight of 0.034 pounds, it is engineered for use in CNC machining centers and drilling operations requiring consistent, repeatable results.

This drill body is suited for production machining environments where replaceable-tip drills reduce downtime compared to brazed or solid-drill alternatives. The CoroDrill 870 series is a common platform in aerospace, automotive, and general engineering shops running medium to high-volume drilling cycles. The GP geometry is a general-purpose profile appropriate for a broad range of workpiece materials. Installation of a fresh 870-1400-14-GP tip into this body restores full cutting performance without replacing the entire tool assembly.

Key Features

• 14mm (0.5512 inch) cutting diameter with GP insert geometry
• Solid carbide tip, manufacturer grade 4334, for wear resistance in challenging materials
• TiAlN PVD coating for high-temperature performance and extended tool life
• 152-degree included angle for controlled entry and reduced thrust force
• CoroDrill 870 series platform supports quick tip replacement at the machine
• Insert seat size 14 — accepts matching 870-series replaceable tips

Compatibility

Designed for use with the SANDVIK COROMANT CoroDrill 870 series drill body system, insert seat size 14. Tip part number 870-1400-14-GP in grade 4334 is the corresponding replaceable tip for this seat size.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or tooling technician. Before changing the tip, ensure the machine spindle is fully stopped, locked out, and all power is de-energized per facility lockout/tagout procedures. Use the correct torque wrench and SANDVIK COROMANT assembly tools specified for the CoroDrill 870 system — do not over-torque or under-torque the tip screw, as improper seating affects runout and tip security. Inspect the insert pocket and locating surfaces for chips or debris before seating the new tip.
