Kennametal 1528423 Indexable Insert Drill 63.5mm 2.5xd

Product Description

The KENNAMETAL 1528423 is a DFT-series indexable insert drill designed for general-purpose drilling in metal-cutting applications. The body is constructed from steel and accepts two DFT-style inserts in size 0905, secured by M5-0.8x12.5 T20 insert lock screws. The drill operates with right-hand cutting direction and features coolant-through capability with axial concentric entry, making it well suited for deep-hole drilling operations where chip evacuation and tool life are critical concerns. Overall length is 12.5 inches, with a 2-inch Weldon Flat and Flange shank for secure machine tool retention. The unit weighs 9.69 pounds.

This indexable insert drill is intended for use in CNC machining centers, vertical mills, and horizontal boring machines in production and job-shop environments. The 2.5xD depth-to-diameter ratio supports drilling to a maximum depth of 158.75 mm (6.25 inches) in a single pass without peck cycles in suitable materials. The DFT insert compatibility and the 63.5 mm nominal diameter make this tool appropriate for large-bore drilling operations across steel, cast iron, and similar workpiece materials in both high-volume and intermittent production settings.

Key Features

• DFT-series indexable insert platform accepts two DFT0905 inserts for rapid edge indexing without regrinding
• Coolant-through design with axial concentric entry supports chip flushing at depth
• Weldon Flat and Flange shank provides positive drive and axial retention in the spindle
• 2.5xD depth ratio allows 158.75 mm maximum drill depth in a single tool setup
• Body side and shank-end coolant ports with threaded connections for flexible coolant routing
• Right-hand cutting direction; general-purpose performance rating across common ferrous workpiece materials

Compatibility

Compatible with DFT drill style toolholders and machines accepting a 2-inch Weldon Flat and Flange shank. Insert compatibility: DFT0905 series inserts (compatible insert size code 0905). Maximum drill diameter with compatible inserts: 67.31 mm (2.650 inches).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked before mounting or removing the tool. Verify shank seating and confirm coolant port connections are properly fitted before initiating a cut. Follow the machine tool manufacturer torque specifications for drawbar or set-screw retention on Weldon Flat shanks. Inspect insert seating and lock screw engagement before each production run.
