Iscar 3202476 Replaceable-tip Drill Weldon Flat Shank

Product Description

The ISCAR 3202476 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metal-cutting applications. The tool accepts a range of interchangeable drill-tip inserts, allowing technicians to swap worn tips without replacing the entire drill body. It covers a drilling diameter range of 0.315 to 0.35 inches, reaches a maximum drill depth of 2.52 inches, and features an overall length of 4.9 inches. The 1/2-inch Weldon Flat shank provides positive, slip-resistant seating in compatible toolholders. Through-coolant capability delivers cutting fluid directly to the cutting zone, supporting chip evacuation and tip life in high-cycle production environments. This tool is installed by machinists and CNC operators working in job shop, manufacturing, or maintenance machining settings.

The 3202476 drill body is suited for holemaking operations requiring an 8xD depth-to-diameter ratio in a compact, rigid platform. Its DCN toolholder style and Weldon Flat shank make it appropriate for CNC machining centers and manual mills equipped with matching collet or set-screw holders. Compatible insert styles include FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M, giving operators flexibility to select tip geometry based on material and application. The through-coolant design makes it particularly effective in stacked-part or deep-hole operations where flood coolant alone is insufficient for chip clearance.

Key Features

• Replaceable-tip design accepts FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M insert styles
• Drilling diameter range: 0.315 to 0.35 inches
• Maximum drill depth: 2.52 inches at 8xD depth-to-diameter ratio
• Through-coolant construction for direct chip and heat management at the cutting edge
• 1/2-inch Weldon Flat shank for positive anti-rotation retention in toolholders
• Conforms to ISO 13399 tooling data standards for CNC integration

Compatibility

Compatible insert styles for this drill body are FCP, ICK, ICK-2M, ICM, ICP, and iCP-2M. The body uses a DCN toolholder style and a 1/2-inch Weldon Flat shank. It is part of the ISCAR SumoCham series of replaceable-tip drilling tools.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before mounting or tip replacement, ensure the machine spindle is fully stopped and the control is in a safe state. The Weldon Flat shank requires a properly sized set-screw holder torqued per the toolholder manufacturer specifications. Verify through-coolant passages are clear and the coolant supply pressure is within the machine and insert manufacturer guidelines before running the first hole.
