Iscar 3203773 Replaceable-tip Drill 0.472in Drg-mf

Product Description

The ISCAR 3203773 is a replaceable-tip drill designed for precision hole-making in metalworking applications. Built around the DRG-MF toolholder platform, it accepts XCMT-MF and XCMT-MG insert styles, allowing tip replacement without removing the body from the machine. The drill has a 0.472-inch cutting diameter, a maximum drill depth of 1.06 inches, and an overall length of 3.07 inches. Through-coolant delivery via a G-thread coolant port keeps cutting temperatures in check and aids chip evacuation during deep-hole cycles. Machinists and tool-and-die professionals install this drill on CNC machining centers and turning centers where repeatability and fast insert indexing are priorities.

The 3203773 is suited for boring, facing, and internal grooving operations in production and job-shop environments. The 0.63-inch shank diameter mounts in standard toolholders commonly found on vertical and horizontal machining centers. The DRG-MF series body accommodates a maximum drill depth range up to 1.5 inches, giving operators flexibility across varying workpiece thicknesses. The flute length of 1.06 inches and body length of 1.3 inches keep the assembly compact, reducing overhang-related vibration in tight setups. This drill is intended for use by skilled machinists operating CNC equipment where ISCAR-compatible insert tooling is already in use.

Key Features

Compatibility

Designed for use with XCMT-MF and XCMT-MG insert styles within the ISCAR DRG-MF series toolholder platform. Compatible with machining setups that support a 0.63-inch shank diameter and through-coolant supply.

Installation Notes

Installation and insert changes should be performed by a qualified machinist following the machine tool manufacturer's lockout and tool-change procedures. Power down and de-energize the spindle before accessing the toolholder. Verify shank seating and insert clamping torque per ISCAR tooling documentation before resuming cutting operations. Through-coolant connection should be confirmed leak-free at the G-thread port before running the spindle.
