Iscar 3203353 Replaceable-tip Drill Weldon Flat Shank

Product Description

The ISCAR 3203353 is a SumoCham-series replaceable-tip drill body designed for precision holemaking in metal cutting applications. The drill accepts interchangeable cutting inserts, eliminating the need to replace the entire tool body when the cutting edge wears. It covers a diameter range of 0.531 to 0.547 inches with a maximum drilling depth of 0.8 inches. The 5/8-inch Weldon flat shank provides positive rotational drive in standard toolholders. Through-coolant capability delivers cutting fluid directly to the cutting zone, supporting tool life and chip evacuation in deep-hole operations. Machinists and tool-and-die professionals are the primary installers of this DCN-style toolholder body.

This drill body is suited for production and job-shop holemaking where frequent insert changes are more cost-effective than reground solid drills. The through-coolant design makes it practical for use in CNC machining centers equipped with high-pressure coolant delivery. The 3.35-inch overall length and 1.46-inch body length fit standard spindle setups without excessive overhang. The tool meets ISO 13399 standards for tooling data representation, making it compatible with CAM and tooling management software that support that protocol.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool body from the toolholder. Confirm the Weldon flat is fully seated against the set screw before operation. Connect the coolant-through circuit per the machine tool manufacturer specifications before running the tool at rated feed and speed.
