Kennametal 1528409 Indexable Insert Drill 2.5xd

Product Description

The KENNAMETAL 1528409 is a straight-shank indexable insert drill designed for production drilling in metal-cutting applications. Built on the DFT series platform, this drill body accepts two DFT0905 indexable inserts to deliver a maximum bore diameter of 2.25 inches (57.15 mm) at a depth-to-diameter ratio of 2.5xD. The 2-inch Weldon Flat and Flange shank provides positive drive torque transfer and is compatible with standard milling machine and machining center spindle toolholders. At 7.37 pounds, this is a solid-steel body tool intended for CNC and manual boring mill setups where consistent, repeatable hole quality is required. Installation and insert changes are handled by machinists and toolroom technicians.

This drill body is suited for general-purpose through-hole and blind-hole drilling in steel, cast iron, and similar ferrous workpiece materials. The 2.5xD ratio makes it appropriate for moderate-depth holes where chip evacuation is manageable without extended-reach tooling. Coolant-through capability via both axial concentric entry and body-side ports supports high-speed cutting with flood or high-pressure coolant delivery. The DFT series is a modular system, and this body size is positioned for mid-range bore diameters up to 2.25 inches.

Key Features

• Accepts two DFT0905 indexable inserts for repeatable edge geometry without regrinding
• Maximum drill depth of 5 inches (127 mm) with a 2.5xD depth-to-diameter ratio
• Coolant-through design with axial concentric entry; body-side port thread 1/8-27 inch, shank-end port thread 1/4-18 inch
• Weldon Flat and Flange shank (2-inch diameter) for positive drive and reduced pullout risk
• Overall length of 11 inches; flute length 5 inches; body length 7 inches
• Right-hand cutting direction; steel tool body for rigidity in interrupted and continuous cuts

Compatibility

Compatible with DFT drill style inserts; insert style code DFT0905, insert size 9.92 x 5.25 mm (0.391 x 0.207 inches). Insert lock screw specification is M5-0.8 x 12.5 T20. Compatible with 2-inch straight Weldon Flat and Flange shank toolholders on CNC machining centers and boring mills.

Installation Notes

This tooling is installed and serviced by machinists or toolroom technicians. De-energize and lock out the machine spindle before mounting the drill body or indexing inserts. Verify shank seating and set-screw torque against the machine toolholder manufacturer specifications before running. Confirm coolant port connections are clear and delivering adequate flow before engaging a cut at full feed rate.
