Iscar 3203350 Replaceable-tip Drill 0.492-0.508 in Sumocham

Product Description

The ISCAR 3203350 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metalworking and machining operations. The drill accommodates a diameter range of 0.492 to 0.498 inches minimum and up to 0.508 inches maximum, with a maximum drilling depth of 0.74 inches. It features a 5/8-inch (0.625 inches) straight-cylindrical shank and an overall length of 3.27 inches. Through-coolant capability keeps cutting zones at working temperature and clears chips efficiently during operation. This body is designed for use with interchangeable drill tip inserts, making tip changes fast without removing the body from the spindle.

The ISCAR 3203350 is suited for production holemaking in CNC machining centers and turning centers where consistent bore diameter and chip control are required. The DCN R toolholder-style body fits into standard straight-cylindrical collets and tool holders. The SumoCham platform is widely used in automotive, aerospace, and general metalworking applications where repeatable hole quality and insert interchangeability reduce downtime. This drill body is compatible with multiple insert styles to match different workpiece materials and cutting conditions.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before inserting or removing the drill body or changing tips. Seat the straight-cylindrical shank fully in the collet or tool holder and torque the clamping nut per the machine manufacturer specification. Verify coolant-through passages are clear and that coolant pressure meets the machining setup requirements before starting the cut.
