Iscar 3202447 Replaceable-tip Drill 0.512-0.528 in Weldon

Product Description

The ISCAR 3202447 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metalworking and machining applications. It accepts a range of interchangeable insert tips, allowing the tool body to be reused while only the cutting insert is replaced. The drill covers a diameter range of 0.512 to 0.528 inches and reaches a maximum depth of 2.56 inches. Through-coolant capability is built in, directing coolant directly to the cutting zone for improved chip evacuation and tool life. The 5/8-inch Weldon flat shank provides secure rotational drive in compatible tool holders.

This drill body is intended for professional machining environments — production shops, tool rooms, and CNC machining centers where repeatable hole quality and fast insert changeout are priorities. The DCN toolholder style and SumoCham series design make it well suited to medium-diameter holemaking in steel, cast iron, and similar materials. The replaceable-tip system reduces downtime compared to solid carbide drills by eliminating the need to remove and regrind or replace the entire tool assembly.

Key Features

• Replaceable-tip design accepts FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M insert styles
• Through-coolant construction for direct coolant delivery to the cutting edge
• Weldon flat shank for positive anti-rotation drive in the holder
• 5xD depth-to-diameter ratio for deep hole capability relative to drill diameter
• Complies with ISO 13399 tooling data standards for integration with CAM and tool management systems
• Overall length of 5.14 inches with a body length of 3.25 inches for reach in standard setups

Compatibility

Compatible insert styles: FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M. Designed for use in DCN-style toolholders with a 5/8-inch Weldon flat shank interface.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized Weldon flat holder before tightening set screws. Verify coolant passages are clear and through-coolant is enabled at the machine before operation. Follow the insert manufacturer torque specifications when seating replacement tips, and inspect the tool body for wear or damage at each insert change.
