Sandvik Coromant 7357727 Carbide Replaceable Tip Drill 14.29mm

Product Description

The SANDVIK COROMANT 7357727 is a solid carbide replaceable tip drill designed for precision hole-making in metalworking and machining applications. It features a 14.29mm (0.5626 inch) cutting diameter and belongs to the CoroDrill 870 series, a platform built around interchangeable carbide tips that reduce tooling cost without sacrificing rigidity or accuracy. The tip carries an AlTiCrN coating applied via PVD process, which provides high-temperature resistance and extended tool life in ferrous and hardened materials. The MM insert geometry and 142-degree included angle are suited to demanding drilling conditions. This tool is installed and changed out by machinists and CNC operators in production and job-shop environments.

The CoroDrill 870 replaceable tip system is used in CNC machining centers, turning centers with live tooling, and dedicated drilling machines across both job-shop and high-volume production settings. The 14.29mm diameter makes it suitable for applications requiring close-tolerance holes in steel, stainless steel, and cast iron workpieces. The replaceable tip design allows the carbide cutting head to be swapped at the machine without removing the steel shank body, reducing changeover time. Machinists working in aerospace, automotive, and general engineering sectors commonly specify this series for its repeatability and tip-change convenience.

Key Features

• 14.29mm (0.5626 inch) cutting diameter with MM insert geometry
• Solid carbide tip, manufacturer grade 2334, for rigidity and wear resistance
• AlTiCrN coating via PVD process for high-temperature and abrasion resistance
• 142-degree included angle optimized for chip formation in common workpiece materials
• Insert seat size 14, compatible with the CoroDrill 870 shank body platform
• Replaceable tip design reduces per-hole tooling cost versus indexable inserts or solid drills

Compatibility

Designed for use with CoroDrill 870 series shank bodies accepting insert seat size 14. Confirm shank body compatibility using the CoroDrill 870 system pairing guide before ordering. No additional compatible model numbers were specified in the product data.

Installation Notes

Tip installation and replacement should be performed by a qualified machinist following the tool manufacturer's assembly procedure for the CoroDrill 870 system. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing the tip. Use the correct torque tool as specified by the shank body documentation — do not substitute fasteners or use impact tools. Inspect the insert seat and locating features for chips or contamination before seating a new tip to ensure proper engagement and runout.
