Kennametal 1528369 Indexable Insert Drill 1-1/8in 2.5xd

Product Description

The KENNAMETAL 1528369 is a DFT-series indexable insert drill designed for high-productivity hole-making in steel and general-purpose materials. It accepts two DFT05T3 indexable inserts and produces holes up to 1.125 inches in diameter at a maximum drill depth of 2.5 inches (63.5 mm), operating at a 2.5xD depth-to-diameter ratio. The straight shank features a Weldon flat and flange for secure toolholder engagement, with a 1.5-inch shank diameter. Coolant-through capability is standard, with axial concentric entry at the shank end and a side coolant port, supporting consistent chip evacuation and insert life in demanding drilling applications. Licensed machinists and CNC setup technicians are the primary end users.

This indexable drill is suited for production drilling in machining centers and CNC lathes handling ferrous and general-purpose workpiece materials. The DFT series platform is built for general-purpose drilling where consistent hole quality and insert interchangeability matter. With an overall length of 7.75 inches and a flute length of 2.5 inches, it fits standard tooling setups for medium-diameter drilling operations. The right-hand cutting direction and Weldon flat shank make it compatible with common milling machine and machining center spindle interfaces used in job shop and production environments.

Key Features

• DFT-series platform accepts two DFT05T3 indexable inserts for fast insert changes without removing the body from the spindle
• Coolant-through design with axial concentric entry and 1/4-18 shank-end port for effective chip flushing at depth
• Side coolant port threaded 1/8-27 for additional coolant supply options
• Weldon flat and flange shank style provides positive drive and repeatable axial positioning
• Steel tool body with 2.5xD depth-to-diameter ratio suitable for general-purpose production drilling
• Right-hand cutting direction; insert lock screw is M3-0.5 x 7.2 T9 Torx drive

Compatibility

Compatible with DFT-series indexable inserts in size code DFT05T3. Insert size is 0.208 inches x 0.148 inches (5.29 mm x 3.75 mm). Designed for use in standard Weldon flat toolholders accepting a 1.5-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body. Seat the Weldon flat shank fully into the toolholder and tighten the drive screw to the toolholder manufacturer's specification before operation. Use the correct T9 Torx driver when seating or replacing insert lock screws, and verify coolant lines are clear before engaging the coolant-through system.
