Iscar 3202478 Replaceable-tip Drill Sumocham 0.394-0.429in

Product Description

The ISCAR 3202478 is a replaceable-tip drill body from the SumoCham series, designed for holemaking operations in metal-cutting applications. The drill accepts interchangeable cutting tips, allowing the body to be reused while only the tip is replaced at wear. It covers a diameter range of 0.394 to 0.429 inches and reaches a maximum drill depth of 3.15 inches, corresponding to an 8xD depth-to-diameter ratio. The 5/8-inch Weldon flat shank provides positive rotational drive in standard toolholders. Through-coolant delivery keeps cutting temperatures in check and clears chips at depth. Overall length is 5.68 inches. This tool is installed and operated by machinists and CNC tooling technicians in production and job-shop environments.

The 3202478 drill body is suited for medium-to-deep hole drilling in ferrous and non-ferrous workpieces where consistent hole quality and tool economy are required. The replaceable-tip design is particularly efficient in high-production settings where tip changes can be performed at the machine without removing or re-indicating the body. The Weldon flat shank mounts in DCN-style toolholders. Compatible insert styles include FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M, giving the operator flexibility to match the tip geometry to the specific material and application.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before inserting or removing the drill tip, power down the machine and confirm the spindle is fully stopped. Seat the Weldon flat shank securely in the toolholder and tighten the set screw to the toolholder manufacturer's specification. Verify through-coolant passages are clear and coolant pressure is within the machine tool's rated range before beginning the cut.
