Kennametal 1522109 Indexable Insert Drill 1-1/8 in 4xd Dft

Product Description

The KENNAMETAL 1522109 is a DFT-series indexable insert drill designed for general-purpose drilling in metal cutting applications. It accepts two DFT05T3 insert style inserts and produces holes up to 1.25 inches in diameter at a maximum drill depth of 4.5 inches, representing a 4xD depth-to-diameter ratio. The body is constructed from steel and measures 9.875 inches in overall length, with a 4.5-inch flute length and a 6.125-inch body length. It carries a Weldon Flat and Flange shank measuring 1.5 inches in diameter, providing secure tool holding in compatible holders. Coolant is delivered through an axial concentric entry, with a 1/4-18 shank-end coolant hole thread.

This drill is suited for production and job-shop environments where indexable tooling is preferred over solid carbide or brazed drills. The right-hand cutting direction and general-purpose performance rating make it applicable across a wide range of common workpiece materials. It is typically installed in CNC machining centers, turning centers with live tooling, or manual mills equipped with the appropriate tool holder for a 1.5-inch Weldon Flat and Flange shank. The DFT series indexing system allows worn inserts to be rotated or replaced at the machine without regrinding.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling specialist. Ensure the machine spindle is fully stopped and the tool holder is secured before inserting or removing the drill body. Follow the machine tool manufacturer torque and runout specifications for Weldon Flat shank holders. When replacing inserts, use the correct T9 torx driver for the M3-0.5 insert lock screw and verify seating before resuming cutting operations.
