Sandvik Coromant 7357663 Carbide Replaceable Tip Drill 1/2 in

Product Description

The SANDVIK COROMANT 7357663 is a solid carbide replaceable tip drill insert designed for the CoroDrill 870 modular drilling system. With a 1/2-inch (0.5000-inch) cutting diameter and a 142-degree drill point angle, this insert delivers precise, controlled entry across a wide range of workpiece materials. The TiAlN coating is applied via PVD process, providing thermal resistance and extended tool life in demanding cutting conditions. The PM insert geometry and fine-grain carbide grade 4334 substrate are engineered to maintain edge integrity during high-feed solid drilling operations in both through and blind-hole applications. Installation uses a clamp-style insert holding method for secure, repeatable seating.

This replaceable tip is suited for solid drilling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. It is used in production machining environments where quick insert changes and consistent hole quality are required without replacing the full drill body. The CoroDrill 870 platform is common in CNC machining centers in both job shop and high-volume manufacturing settings. Insert seat size is 11, matching the corresponding CoroDrill 870 drill body.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down the spindle and ensure the machine is in a safe, locked-out state before removing or seating the insert. Use the appropriate Sandvik Coromant torx or clamping key to secure the insert to the specified clamp method — do not over-tighten or substitute non-OEM fasteners. Verify insert seat cleanliness before installation to ensure proper seating and runout accuracy.
