Kennametal 1528410 Indexable Insert Drill 2.5xd

Product Description

The KENNAMETAL 1528410 is a DFT-series indexable insert drill designed for high-productivity hole-making in metal fabrication and machining applications. It accepts two DFT-style indexable inserts and delivers a maximum drill depth of 5.35 inches at a 2.5xD depth-to-diameter ratio. The body is constructed from steel and features a 2-inch Weldon flat and flange shank for secure toolholder engagement. Coolant-through capability via axial concentric entry supports chip evacuation and tool life in demanding cuts. This drill is installed and operated by machinists and CNC tooling specialists on milling machines and machining centers.

The 1528410 is suited for general-purpose drilling in production environments including job shops, tier manufacturing, and aerospace or heavy equipment machining cells. It is designed for use where a full-diameter indexable drill body is preferred over a solid carbide solution, particularly when bore diameters in the 2-3/8-inch range are required. The DFT series body accepts DFT0905 compatible insert geometry, making insert sourcing straightforward within the KENNAMETAL tooling system.

Key Features

• DFT series body accepts two DFT0905-compatible indexable inserts for cost-effective edge changes
• Coolant-through design with axial concentric entry improves chip flushing and thermal management
• Weldon flat and flange shank provides positive drive and pullout resistance in the toolholder
• Right-hand cutting direction; compatible with standard CNC machining center spindle rotation
• Body side coolant hole threaded 1/8-27 inches; shank end coolant hole threaded 1/4-18 inches
• Insert lock screw M5-0.8 x 12.5 T20 torx drive for secure insert clamping

Compatibility

Designed for use with DFT-style indexable inserts in size code 0905, specifically compatible insert style DFT0905. Body is compatible with toolholders accepting a 2-inch diameter Weldon flat and flange straight shank.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool is secured in an appropriately rated toolholder before tightening or adjusting insert screws. Use a T20 torx driver to seat insert lock screws; do not overtighten beyond tooling manufacturer recommendations. Verify coolant supply lines are connected and flow is confirmed before initiating a cut to prevent thermal damage to inserts and the drill body.
