Sandvik Coromant 7357623 Carbide Replaceable Tip Drill 12mm

Product Description

The SANDVIK COROMANT 7357623 is a solid carbide replaceable tip drill insert designed for the CoroDrill 870 modular drilling system. Carrying the ISO designation 870-1170-9-PM 4334, this tip delivers a 12.00mm cutting diameter and features a TiAlN coating applied via PVD process for extended wear resistance. The 142-degree drill point angle and helical flute geometry support consistent chip evacuation during solid drilling operations. With an insert seat size of 9 and a PM insert geometry, it is held in place by a clamp mechanism. The manufacturer grade is 4334, produced from fine-grain solid carbide stock. Licensed HVAC, industrial, and precision machining technicians familiar with modular drill systems will recognize the CoroDrill 870 platform as a standard in high-production environments.

This replaceable tip is suited for solid drilling applications across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. It is intended for use in CNC machining centers and production drilling setups where tip replacement extends the life of the drill body. The regular spiral and standard point type make it a versatile choice for through-hole and blind-hole drilling in both short-run and high-volume production contexts.

Installation Notes

Installation and replacement of this tip should be performed by a qualified machinist or tooling technician familiar with the CoroDrill 870 system. The machine spindle must be fully stopped and the tool removed from the spindle or secured in a tool presetter before tip replacement. Follow the manufacturer torque and seating procedures for the clamp mechanism to ensure proper tip retention and runout control. Do not attempt to index or replace the tip while the machine is powered or the coolant system is active.
