Iscar 3203772 Replaceable-tip Drill 0.394 in Through Coolant

Product Description

The ISCAR 3203772 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. Built on the DRG-MF toolholder platform, it accepts XCMT-MF and XCMT-MG series inserts at the cutting end, allowing the tip to be swapped without replacing the full body. The drill has a 0.394-inch diameter, a maximum drill depth of 0.89 inches, and an overall length of 2.73 inches. A through-coolant design delivers cutting fluid directly to the cutting zone, improving chip evacuation and tool life. This body is installed by machinists and toolroom technicians working on CNC machining centers and lathes.

This drill body is suited for boring, facing, and internal grooving operations in production and job-shop environments. The 0.5-inch shank diameter fits standard toolholders commonly found on CNC turning and milling equipment. The DRG-MF series is intended for short-hole drilling work where replaceable-tip tooling reduces downtime versus brazed or solid carbide alternatives. Compatible insert styles are XCMT-MF and XCMT-MG, which are indexed or replaced independently of the body.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer lockout and power-down procedures before tool changes. Ensure the 0.5-inch shank is fully seated and clamped to the specified holder torque listed in the machine or toolholder documentation. Verify coolant port alignment and thread engagement before running through-coolant at operating pressure. Do not exceed the maximum drill depth of 0.89 inches without confirming setup rigidity and chip clearance.
