Kennametal 1528422 Indexable Insert Drill 60.3mm

Product Description

The KENNAMETAL 1528422 is an indexable insert drill designed for production drilling applications in metal cutting environments. The body accepts two DFT-style inserts and delivers a drill depth-to-diameter ratio of 2.5xD, with a maximum drill depth of 5.95 inches. The shank diameter is 2 inches with a Weldon flat and flange configuration, providing positive rotational drive and secure toolholder engagement. Overall length is 12.125 inches. Coolant-through capability is supported via axial concentric entry, with a body side coolant port threaded at 1/8-27 and a shank end port threaded at 1/4-18. This drill is handled by machinists and tool-and-die professionals on CNC machining centers and horizontal boring mills.

This drill is suited for general-purpose drilling in steel and ferrous materials at diameters up to 65.79 mm (2.59 inches maximum drill diameter). The straight shank with Weldon flat seats into standard toolholders designed for that shank profile. With a flute length of 5.95 inches and a body length of 8.125 inches, it fits applications requiring moderate depth drilling in a single pass. The DFT series insert compatibility with size code 0905 provides a wide range of insert grade options for varied workpiece materials and cutting conditions.

• Coolant-through design with axial concentric entry for chip evacuation and heat management at the cutting edge
• Weldon flat and flange shank provides positive drive and prevents shank rotation in toolholder
• Right-hand cutting direction; compatible insert style DFT0905.
• Insert lock screw M5-0.8x12.5 T20 drive for positive insert clamping

Compatibility

Compatible with DFT-style inserts using size code 0905 (insert size 9.92x5.25 mm). Insert lock screw specification is M5-0.8x12.5 T20. Designed for use in toolholders accepting a 2-inch straight shank with Weldon flat and flange. No additional model-specific compatibility was stated in the product data.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the spindle drive before loading or unloading the drill body from the toolholder. Torque insert lock screws using the correct T20 driver; follow the insert manufacturer torque guidance for the M5 screw specification. Verify coolant supply connections at both the body side port and shank end port before initiating a cutting cycle, and confirm chip evacuation is not obstructed during deep-hole passes.
