Iscar 3203024 Replaceable-tip Drill Weldon Flat Through Coolant

Product Description

The ISCAR 3203024 is a replaceable-tip drill body designed for holemaking operations in metalworking environments. It accepts a range of drill tip inserts across the FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M styles at seat size 21, allowing the cutting tip to be swapped without replacing the entire tool body. The drill covers a diameter range of 21.01 to 21.89 mm and reaches a maximum drill depth of 62.99 mm, representing a 3xD depth-to-diameter ratio. Through-coolant capability is built in, directing coolant directly to the cutting zone for improved chip evacuation and tool life in deep-hole applications. Overall length is 150.62 mm and the Weldon flat shank measures 21.01 mm in diameter, providing positive drive in compatible toolholders.

This drill body is part of the ISCAR UniSumoCham series and carries a DCNS toolholder style designation. It is suited for production drilling in CNC machining centers and turning centers where consistent hole quality and rapid tip replacement are priorities. The replaceable-tip design reduces downtime compared to solid-body indexable drills, making it practical for high-volume shops running steel, cast iron, and similar workpiece materials. The through-coolant feature supports both flood and high-pressure coolant systems commonly found in industrial machining environments. Installation and use are performed by machinists and CNC operators familiar with indexable tooling systems.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body. Secure the Weldon flat shank in a compatible toolholder to the toolholder manufacturer's specified clamping procedure. Verify the insert tip is properly seated and locked before initiating any cutting cycle.
