Iscar 3201740 Replaceable-tip Drill Weldon Flat Sumocham

Product Description

The ISCAR 3201740 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metal cutting applications. The drill accepts a range of interchangeable insert tips, enabling diameter flexibility from 0.827 to 0.862 inches without replacing the entire tool body. With a maximum drill depth of 4.13 inches at a 5xD depth-to-diameter ratio and through-coolant capability, the 3201740 supports high-productivity drilling in ferrous and non-ferrous materials. The Weldon flat shank measures 1 inch in diameter and is suitable for standard end-mill holders. This tool is intended for machinists, toolroom technicians, and CNC operators working in production or job-shop environments.

The ISCAR 3201740 is used in CNC machining centers and drilling operations requiring consistent hole quality at moderate-to-deep depths. The through-coolant design delivers cutting fluid directly to the tip, reducing heat buildup and extending insert life in demanding applications. The DCN toolholder style and Weldon flat shank configuration make it compatible with a wide range of standard machine spindles. Compatible insert styles include FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M, giving the operator flexibility in selecting tip geometry for specific materials and surface finish requirements.

Compatibility

Compatible insert styles for this drill body are FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M. The DCN-series body is part of the ISCAR SumoCham platform. Specific machine compatibility depends on spindle toolholder configuration and available through-coolant supply.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Secure the Weldon flat shank firmly in a matched end-mill holder and verify axial runout before beginning a cut. Ensure through-coolant supply pressure and flow rate are adequate for the application before operation. Confirm insert tip is fully seated and locked per the manufacturer torque procedure before cycling the spindle.
