Iscar 3202290 Replaceable-tip Drill 0.315-0.331in Weldon Shank

Product Description

The ISCAR 3202290 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metal cutting applications. It accepts a range of interchangeable drill tip inserts, allowing the body to be reused while only the cutting tip is replaced. The drill accommodates diameters from 0.315 to 0.331 inches and reaches a maximum drill depth of 0.94 inches. A 1/2-inch Weldon Flat shank provides secure, anti-rotation clamping in compatible toolholders. Through-coolant capability delivers cutting fluid directly to the cutting zone, improving chip evacuation and extending insert life during deep hole operations.

The 3202290 is suited for CNC machining centers and drilling operations in production environments where consistent hole tolerances and high throughput are priorities. The replaceable-tip design reduces downtime by eliminating the need to change the entire drill body when the cutting edge wears. With a 3xD depth-to-diameter ratio and an overall length of 3.32 inches, this drill body fits standard tooling setups in shops running tight-tolerance holemaking work on steel, cast iron, and similar materials.

Key Features

• Replaceable-tip design: drill body is reusable; only the insert tip is replaced at wear
• Through-coolant capability for improved chip evacuation and insert life
• Compatible with FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M insert styles
• 1/2-inch Weldon Flat shank provides anti-rotation retention in toolholders
• 3xD drill depth-to-diameter ratio for standard-depth holemaking
• Conforms to ISO 13399 tooling data standards for CAM system integration

Compatibility

Compatible insert styles include FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M. Toolholder style is DCN. Designed for use in CNC machining setups with through-coolant capability and 1/2-inch Weldon Flat shank retention.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before inserting or removing the drill body or tip inserts. Verify that the Weldon Flat shank is fully seated and the set screw is torqued per the machine tool manufacturer specification before operation. Ensure through-coolant supply is confirmed at the spindle before running to avoid dry cutting at the insert tip.
