Sandvik Coromant 7357850 Carbide Replaceable Tip Drill 17mm

Product Description

The SANDVIK COROMANT 7357850 is a solid carbide replaceable tip drill designed for precision hole-making in metalworking and machining applications. It carries a cutting diameter of 17mm (0.6693 inches) and belongs to the CoroDrill 870 series, a platform built around interchangeable carbide tips that allow fast tip changes without removing the drill body from the spindle. The tip features a 142-degree included angle and a TiAlN coating applied via PVD process, providing heat resistance and extended tool life in steel and cast iron cutting. This drill is installed and operated by machinists and CNC operators in production and job-shop environments.

The 7357850 is suited for drilling operations in general machining, die-and-mold, and production environments where consistent hole quality and reduced downtime matter. The CoroDrill 870 platform is commonly used on CNC machining centers and turning centers. The PM insert geometry is optimized for smooth chip evacuation and stable cutting action. This drill does not include through-coolant capability, making it appropriate for applications where external or flood coolant is used. Grade 4334 indicates a PVD-coated carbide grade intended for a broad range of ISO P and ISO K workpiece materials.

Compatibility

Designed for use with the SANDVIK COROMANT CoroDrill 870 series drill body platform accepting size 17 insert seats. Specific compatible drill body part numbers should be confirmed using the SANDVIK COROMANT CoroDrill 870 selection tool or product catalog.

Installation Notes

Installation and tip changes should be performed by qualified machinists with the spindle fully stopped and the machine placed in a safe, locked-out state. Use the appropriate SANDVIK COROMANT torque tool and seating procedure as specified by the drill body documentation — do not over-tighten or seat the tip with improvised tools. Verify tip engagement and runout before initiating a cut. Follow shop-floor safety practices and applicable OSHA machining standards when handling carbide cutting tools.
