Kennametal 1528393 Indexable Insert Drill 1.437in 2.5xd

Product Description

The KENNAMETAL 1528393 is a DFT-series indexable insert drill engineered for production drilling in metal-cutting applications. It accepts two DFT-style inserts (size code 06T3) and cuts up to 1.437 inches in diameter with a maximum drill depth of 3.3 inches, delivering a 2.5xD depth-to-diameter ratio. The shank diameter is 1.5 inches with a Weldon flat and flange configuration for secure tool holding. Overall length is 8.625 inches. Coolant is delivered axially through the tool body, supporting chip evacuation and insert life in continuous-feed operations. The tool body is constructed of steel and is designed for right-hand cutting.

This drill is suited for general-purpose drilling on CNC machining centers and manual machine tools where indexable-insert tooling is preferred over brazed or solid-carbide designs. The 1.5-inch straight shank with Weldon flat seats directly into standard tool holders and CAT or BT arbors equipped with matching bore diameters. Typical applications include production-volume hole making in steel, cast iron, and similar ferrous materials in job-shop and manufacturing environments. The axial coolant entry supports both flood and high-pressure through-spindle coolant systems.

Key Features

• DFT-series drill body accepts two DFT06T3 indexable inserts for fast insert changes without removing the holder from the spindle
• 1.437-inch maximum drill diameter with 2.5xD depth ratio delivers a 3.3-inch maximum drill depth
• Weldon flat and flange shank (1.5-inch diameter) provides positive drive and axial location
• Axial concentric coolant entry (1-axial concentric entry) keeps inserts and the bore cool during high-feed passes
• Body-side coolant port threaded 1/8-27 and shank-end port threaded 1/4-18 for flexible coolant plumbing
• Right-hand cutting direction; general-purpose tool performance rating suitable for a broad range of ferrous work materials

Compatibility

Compatible with DFT-style inserts, insert size code 06T3 (insert size 0.260 x 0.148 inches). Insert lock screw specification is M3.5-0.6 x 8.3 T15. Designed for use in tool holders accepting a 1.5-inch straight shank with Weldon flat and flange retention.

Installation Notes

Installation should be performed by a qualified machinist or tooling setup technician. Ensure the machine spindle is fully stopped and the CNC program is in a safe state before loading or removing the drill body. Torque the insert lock screws using the appropriate T15 Torx driver to the insert manufacturer's specified value. Verify coolant passages are clear and the appropriate thread sealant or fittings are used at the 1/8-27 body-side and 1/4-18 shank-end coolant ports before running the tool under pressure.
