Sandvik Coromant 7357874 Carbide Replaceable Tip 17.5mm

Product Description

The SANDVIK COROMANT 7357874 is a solid carbide replaceable tip drill designed for precision hole-making in metalworking and machining applications. It belongs to the CoroDrill 870 series and accepts a PM-geometry insert in seat size 17. The cutting diameter measures 17.5mm (0.689 inches), and the drill tip features a 142-degree included angle optimized for self-centering entry and controlled chip formation. The TiAlN coating is applied via a PVD process, delivering heat resistance and extended tool life in ferrous and hard materials. This tip is sold individually and is intended for use by machinists and toolroom technicians working on CNC machining centers or drill presses.

This replaceable tip is suited for production drilling in ferrous metals, cast iron, and similar workpiece materials where consistent hole quality and repeatable positioning are required. The CoroDrill 870 platform is a modular drilling system that allows tip replacement without removing the drill body from the spindle, reducing changeover time on the shop floor. The PM insert geometry supports stable cutting action across a range of feed rates typical in precision component manufacturing and job shop environments.

Key Features

Installation Notes

Installation of replaceable carbide drill tips should be performed by a qualified machinist following the tool manufacturer's torque and seating guidelines for the CoroDrill 870 system. Ensure the spindle is fully stopped and the machine is in a safe state before changing the tip. Inspect the insert seat for chips, debris, or damage before seating a new tip, as contamination can affect runout and tip retention. Follow applicable shop safety procedures and machine tool manufacturer guidelines during all tooling changes.
