Kennametal 1527687 Indexable Insert Drill 25mm 2.5xd

Product Description

The KENNAMETAL 1527687 is an indexable insert drill from the Drill-Fix series, designed for production drilling in steel and ferrous materials. The body accepts two DFT-style inserts and delivers a 25mm (0.9843 inch) drill diameter with a maximum drill depth of 63.5mm (2.5 inches), corresponding to a 2.5xD depth-to-diameter ratio. The straight cylindrical shank measures 1 inch in diameter and 3 inches in length, providing rigid tool holding in standard drill chucks or collet-style toolholders. Coolant-through capability supports both body-side and shank-end delivery, making this drill suitable for high-speed, chip-clearing applications in CNC machining centers and drill presses.

The 1527687 is suited for medium-batch and high-production drilling operations in machining environments where consistent hole quality and insert interchangeability are required. The Drill-Fix series is commonly applied in job shops and production facilities running steel and similar materials. The straight-shank interface makes this drill compatible with standard toolholding systems found on vertical and horizontal CNC machining centers. Maximum drill diameter with offset insert positioning reaches 28.18mm (1.109 inches).

Compatibility

Compatible with DFT-style indexable inserts; specifically takes DFT 05T308 inserts. The 1527687 belongs to the Drill-Fix series and is designed for use in toolholding systems that accept a 1-inch straight cylindrical shank.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body or inserts. Verify insert seating and screw torque per the toolholder and insert manufacturer guidelines before initiating a cut. Confirm coolant line connections at both the body-side and shank-end ports are secure and delivering adequate flow before running at production feed and speed rates.
