Sandvik Coromant 7357615 Carbide Replaceable Tip Drill 11.5mm

Product Description

The SANDVIK COROMANT 7357615 is a solid carbide replaceable tip drill designed for precision hole-making in metal cutting applications. It belongs to the CoroDrill 870 series and features a 11.5mm (0.4528 inch) cutting diameter with a 142-degree included angle. The tip is finished with a TiAlN coating applied via a PVD process, which improves wear resistance and thermal stability at the cutting edge. The insert geometry is PM and fits an insert seat size 9. This drill is sold individually per package and is intended for use by machinists and tool-and-die professionals working in production or job-shop environments.

The 7357615 fits into the CoroDrill 870 replaceable tip drill platform, making it suited for moderate-to-high volume drilling operations in steel, stainless steel, and similar ferrous materials. The replaceable tip design allows the carbide cutting tip to be swapped out without replacing the full drill body, reducing tooling cost per hole over time. It is appropriate for use on CNC machining centers and lathes with driven tool capability where consistent hole geometry and dimensional accuracy are required.

Key Features

• Solid carbide tip with TiAlN coating for extended wear life in ferrous materials
• PVD coating process preserves sharp edge geometry on the cutting tip
• 142-degree included angle optimized for flat-bottom entry and reduced thrust force
• PM insert geometry suited for stable cutting in a range of steel grades
• Replaceable tip design reduces tooling cost compared to solid carbide drills
• Insert seat size 9 compatible with CoroDrill 870 series drill bodies

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 series drill bodies that accept insert seat size 9. Specific compatible drill body part numbers should be confirmed using the SANDVIK COROMANT CoroDrill 870 selection guide for the 11.5mm tip diameter.

Installation Notes

Installation of replaceable carbide tips should be performed by a qualified machinist following the tool manufacturer's torque and seating procedure for the CoroDrill 870 platform. The drill body and tip seating surfaces should be clean and free of chips before assembly. Always verify spindle runout and coolant line condition before resuming cuts. Do not force or impact the carbide tip during installation, as solid carbide is brittle and susceptible to edge chipping.
