Kennametal 3022047 Indexable Insert Drill 4xd Dfr

Product Description

The KENNAMETAL 3022047 is an indexable insert drill designed for general-purpose drilling applications in metal-cutting environments. It accepts two DFR-style inserts and delivers a maximum drill depth of 50.8mm (2 inches) at a 4xD depth-to-diameter ratio. The drill body measures 12.7mm (0.500 inch) in nominal diameter with a maximum drill diameter of 13.72mm (0.540 inch). The straight shank features a Weldon flat and flange configuration with a 3/4-inch (0.750-inch) shank diameter. Coolant-through capability is built in via axial concentric entry, supporting consistent chip evacuation and tool life in production drilling setups. Licensed machinists and toolroom technicians are the primary installers and operators.

This drill is suited for general-purpose drilling in machining centers and CNC lathes where indexable tooling is preferred over solid carbide for cost-per-hole efficiency. The DFR series platform is intended for steel and similar workpiece materials. The straight shank with Weldon flat and flange is compatible with standard tool holders used in production and job-shop environments. Insert size code 0202 applies, with compatible inserts designated DFR0202. The overall length of 4-61/64 inches (4.953 inches) makes it appropriate for moderate-reach applications without extended-reach tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with indexable tooling systems. Power down and lock out the machine spindle before changing inserts or mounting the drill body. Use the specified T6 torx key for insert screw installation and do not exceed the screw engagement specified for the M2-0.4 insert lock screw. Verify coolant line connections at the 1/8-27 threaded ports are leak-free before initiating a cut cycle.
