Kennametal 1522105 Indexable Insert Drill 1.5in 4xd Dft

Product Description

The KENNAMETAL 1522105 is a straight-shank indexable insert drill designed for general-purpose drilling in metal fabrication and machining applications. It accepts two DFT-style inserts and delivers a maximum drill depth of 5.5 inches (139.7 mm) at a 4xD depth-to-diameter ratio. The drill body measures 1.5 inches in diameter with a matching 1.5-inch Weldon Flat and Flange shank, providing a secure, torque-resistant connection in the spindle. Overall tool length is 11 inches. Coolant-through capability is included via axial concentric entry, supporting chip evacuation and insert life in production drilling environments. This tool is installed and operated by machining professionals and CNC setup technicians.

The 1522105 is suited for straight-hole drilling operations in ferrous and non-ferrous materials where a 1.5-inch diameter bore is required. Its DFT series designation means it is paired with DFT06T3 compatible inserts, which are indexed rather than reground, reducing downtime during insert changes. The 4xD ratio makes it appropriate for moderate-depth holes in workpieces encountered in job shops, production machining cells, and general manufacturing. Right-hand cutting direction is standard.

Key Features

• 1.5-inch maximum drill diameter with 4xD depth-to-diameter ratio for consistent bore geometry
• Accepts 2 DFT06T3 indexable inserts - no regrinding required between changes
• Coolant-through design with axial concentric entry for improved chip evacuation and insert longevity
• Weldon Flat and Flange shank provides positive drive and reduces pullout risk
• Steel tool body construction rated for general-purpose drilling performance
• Shank end coolant hole thread size of 1/4-18 for direct coolant connection

Compatibility

Compatible with DFT drill style toolholders and DFT06T3 indexable inserts (insert size 6.62 x 3.75 mm / 0.26 x 0.148 inches). Insert lock screw specification is M3.5-0.6 x 8.3 T15.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. The machine spindle must be fully stopped and the tool changer or spindle locked before mounting or dismounting the drill body. Verify that the Weldon Flat is properly seated against the drive flat in the holder before tightening the set screw. Confirm coolant line pressure compatibility with the axial concentric entry port before enabling coolant-through flow.
