Iscar 3201737 Replaceable-tip Drill 0.709-0.744 in Weldon

Product Description

The ISCAR 3201737 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metalworking and industrial machining applications. The drill accommodates a diameter range of 0.709 to 0.744 inches and reaches a maximum drilling depth of 3.54 inches, with a depth-to-diameter ratio of 5xD. It features a 1-inch Weldon flat shank and through-coolant capability for chip evacuation and heat management during high-production drilling operations. Licensed machinists and CNC operators install this toolholder body as part of a modular drill system using interchangeable indexable inserts.

This drill body is suited for production machining environments where consistent bore quality and rapid tip changeover are required. The DCN-style toolholder body accepts FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M insert styles, providing flexibility across different workpiece materials and cutting conditions. With an overall length of 6.87 inches and a body length of 4.67 inches, it is appropriate for both vertical machining centers and horizontal boring setups where a 1-inch Weldon flat interface is used.

Installation Notes

Installation and changeover should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is locked out before changing inserts or mounting the drill body. Secure the Weldon flat shank in a compatible toolholder to the torque specification provided by the toolholder manufacturer. Verify through-coolant passages are clear and that coolant pressure is set per the machining center specifications before initiating a cut.
