Kennametal 5691799 Indexable Insert Drill 1-3/8 in 3xd

Product Description

The KENNAMETAL 5691799 is a 3xD indexable insert drill designed for general-purpose drilling operations in metal cutting applications. It accepts two indexable inserts and delivers a maximum drill depth of 4.125 inches with a cutting diameter of 1.375 inches. The drill body is constructed from steel and features a 1.25-inch Weldon flat flange shank for secure, repeatable tool holding in compatible spindles. Coolant delivery is available through axial concentric and radial ports, with threaded coolant entry at both the shank end and body side, supporting high-performance through-coolant setups. This tool is intended for installation and use by machinists and CNC tooling professionals.

The 5691799 is suited for production drilling in ferrous and general-purpose workpiece materials where a 3xD depth-to-diameter ratio is required. The right-hand cutting configuration and flange shank make it compatible with standard milling machine and machining center spindle setups. The DFSP series body accepts DFT06T3 and SPPX1204 family inserts, giving tooling engineers flexibility in insert selection based on workpiece material and cutting parameters. Typical applications include roughing drill cycles in horizontal and vertical machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the drill body. Confirm shank seating and flange contact before torquing the retention fastener to the machine manufacturer's specified value. Verify insert orientation, clamping screw engagement, and coolant line connections before resuming cutting operations.
