Sandvik Coromant 7357716 Replaceable Tip Drill 14mm Corodrill 870

Product Description

The SANDVIK COROMANT 7357716 is a replaceable tip drill from the CoroDrill 870 series, designed for precision hole-making in metalworking and machining applications. It features a 14mm (0.5512 inch) cutting diameter, a 142-degree included angle, and is built from solid carbide with a TiAlN (Titanium Aluminum Nitride) coating applied via a PVD process. The TiAlN finish improves wear resistance and heat tolerance, making this drill suitable for demanding cutting operations. Insert geometry is PM, and the insert seat size matches the 14mm platform. This tool is installed and used by machinists and CNC operators in production and job-shop environments.

The 7357716 fits into the CoroDrill 870 replaceable tip drill system, where the carbide tip is exchanged at the machine without removing the drill body from the spindle. This design reduces downtime and tooling cost in high-volume drilling operations. Typical applications include drilling into steel, stainless steel, and cast iron in both horizontal and vertical machining centers. The PM insert geometry is suited for stable cutting conditions where consistent hole quality and diameter tolerance are priorities.

Key Features

• 14mm cutting diameter (0.5512 inch) for precise metric-standard hole sizing
• Solid carbide construction with manufacturer grade 4334 for rigidity and wear life
• TiAlN coating via PVD process for enhanced heat and abrasion resistance
• 142-degree included angle optimized for the CoroDrill 870 replaceable tip platform
• PM insert geometry for stable, controlled cutting performance
• Replaceable tip design allows tip exchange at the spindle, reducing changeover time

Compatibility

Designed for use with the SANDVIK COROMANT CoroDrill 870 series replaceable tip drill body system using insert seat size 14.

Installation Notes

Installation and tip exchange should be performed by a qualified machinist following the machine tool manufacturer lockout and power-down procedures before any tooling change. Use the recommended torque tool and seating method specified in the CoroDrill 870 system documentation to ensure proper tip engagement. Inspect the insert seat for debris or damage before seating a new tip. Do not exceed the cutting parameters established for the grade and coating combination.
