Kennametal 1527688 Indexable Insert Drill 2.5xd Dft

Product Description

The KENNAMETAL 1527688 is a DFT-series indexable insert drill designed for precision hole-making in steel and general-purpose machining applications. Built with a straight shank featuring a Weldon Flat and Flange configuration, this drill accepts two DFT05T3 indexable inserts and delivers a drill depth-to-diameter ratio of 2.5xD. The 25.4mm (1 inch) shank diameter and overall length of 7 inches provide rigid support in standard toolholding setups. Coolant-through capability with axial concentric entry keeps cutting zones cool and aids chip evacuation during deep drilling cycles. Licensed machinists and CNC programmers working in production environments will find this tool suited to consistent, repeatable drilling performance.

This indexable insert drill is intended for general-purpose drilling operations in metalworking environments, including job shops and production machining facilities. The 2.5xD depth ratio makes it well suited for drilling depths up to 63.5mm (2.5 inches) in materials compatible with DFT insert grades. The body side coolant port is threaded at 1/8-27 inch and the shank end port at 1/4-18 inch, supporting both external and through-coolant delivery systems on equipped machines.

Key Features

• 2.5xD depth-to-diameter ratio supports drilling up to 63.5mm deep
• Straight shank with Weldon Flat and Flange for secure toolholder grip
• Coolant-through design with axial concentric entry for effective chip and heat management
• Right-hand cutting direction; general-purpose tool application suitable for steel and similar workpiece materials
• M3-0.5x7.2 T9 insert lock screw for consistent insert seating

Compatibility

Compatible with DFT-style insert systems using insert size code 05T3 (DFT05T3). Designed for use in machine spindles and toolholders accepting a 1-inch straight shank with Weldon Flat and Flange configuration.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before mounting or indexing inserts. Confirm toolholder compatibility with the 1-inch Weldon Flat shank before mounting. Use the correct T9 Torx driver when seating or replacing the M3-0.5x7.2 insert lock screw - do not substitute driver sizes, as improper torque can damage the screw seat.
