Iscar 3203532 Replaceable-tip Drill 1.181-1.216 in Weldon

Product Description

The ISCAR 3203532 is a replaceable-tip drill body from the SumoCham series, designed for holemaking operations in metalworking and machining applications. It accepts a range of FCP, HCP-IQ, ICK, ICK-2M, ICM, ICP, and iCP-2M interchangeable drill tip inserts, allowing a single body to support multiple cutting geometries and materials. The drill covers a diameter range of 1.181 to 1.216 inches with a maximum drill depth of 3.54 inches and an overall length of 7.77 inches. Through-coolant capability delivers cutting fluid directly to the tip for improved chip evacuation and tool life at depth. Installed by machinists and CNC operators in production and job-shop environments.

This drill body is suited for use on CNC machining centers and manual mills where 3xD depth-to-diameter ratio drilling is required. The Weldon flat shank with a 1.25 inch shank diameter seats securely in standard side-lock holders, minimizing pullout under the axial loads typical of large-diameter drilling. The DCN A toolholder style and ISO 13399 compliance make this body compatible with modern tooling management systems and digital tool libraries. Typical applications include roughing and semi-finishing bores in steel, cast iron, and other common workpiece materials.

Compatibility

Compatible insert tip styles: FCP, HCP-IQ, ICK, ICK-2M, ICM, ICP, and iCP-2M. Toolholder style is DCN A. Designed for use with standard 1.25 inch Weldon flat side-lock holders on CNC machining centers and milling machines.

Installation Notes

Installation and tip changes should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. Ensure the Weldon flat is properly aligned with the side-lock set screw before tightening to prevent runout. Through-coolant passages should be inspected for obstruction before mounting, and coolant pressure settings should follow the machine tool manufacturer specifications. Handle insert tips with care to avoid chipping the cutting edge prior to engagement.
