Iscar 3202791 Replaceable-tip Drill Sumocham Dcn

Product Description

The ISCAR 3202791 is a replaceable-tip drill designed for precision holemaking in metalworking and machining applications. Part of the ISCAR SumoCham series with a DCN toolholder style, it covers a drilling diameter range of 0.492 to 0.508 inches and reaches a maximum drill depth of 1.47 inches, corresponding to a 3xD depth-to-diameter ratio. The straight-cylindrical shank measures 0.625 inches in diameter, and the overall length is 4.04 inches. Through-coolant capability supports chip evacuation and tool life during continuous drilling operations. This drill body is intended for use by machinists and toolroom professionals working with CNC machining centers and drill presses.

The 3202791 is suited for production holemaking in ferrous and non-ferrous materials where consistent bore diameter and repeatable depth are required. The replaceable-tip design reduces downtime by allowing insert swaps without removing the drill body from the spindle. Compatible insert styles include FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M, giving the user flexibility in cutting geometry and grade selection based on workpiece material. This tool fits standard straight-cylindrical tool holders and collet chucks sized for a 5/8-inch shank.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine spindle fully stopped and the machine locked out per applicable safety procedures. Ensure the shank is fully seated and clamped to the specified holder torque per the tool holder manufacturer's guidelines before operation. Verify through-coolant passages are clear and coolant pressure is appropriate for the machine setup before running. Inspect the replaceable tip for proper seating and secure engagement before each use.
