Kennametal 1522102 Indexable Insert Drill 1-3/4 in 4xd

Product Description

The KENNAMETAL 1522102 is a 4xD indexable insert drill designed for general-purpose drilling in metal fabrication and machining operations. The tool accepts two DFT-style inserts and delivers a maximum drill depth of 177.8mm (7 inches) with a maximum drill diameter of 47.63mm (1.875 inches). Built from steel construction with a 1.5-inch Weldon Flat and Flange shank, the 1522102 features axial concentric coolant entry to support through-coolant flow during high-feed drilling cycles. It is installed and operated by machining professionals and tooling technicians in CNC drilling and milling applications.

The 1522102 fits into standard machining center spindles and CNC drill presses that accept a 1.5-inch Weldon Flat and Flange shank. The DFT series design targets general-purpose drilling in a wide range of workpiece materials. With an overall length of 12.75 inches and a flute length of 7 inches, this tool is suited for reaching moderate depths in structural components, fixtures, and fabricated assemblies. The drill depth by diameter ratio of 4xD makes it appropriate for through-hole and blind-hole applications where controlled chip evacuation is needed.

Key Features

• Steel tool body construction with a 12.75-inch overall length

Compatibility

Compatible with DFT-style indexable inserts using size code 0704 (insert compatibility code: DFT0704). Designed as an OEM-style replacement or standard tooling selection within the KENNAMETAL DFT series drill platform. The insert lock screw specification is M3.5-0.6x12T15 and the shank end coolant hole thread size is 1/4-18 inch.

Installation Notes

Installation and setup should be performed by qualified machining technicians familiar with indexable tooling systems. Power down and lock out the machine spindle before seating or replacing inserts. Confirm that the shank is properly seated and clamped in the tool holder to the machine manufacturer's specifications before initiating a cutting cycle. Verify through-coolant connections at the shank end before operation to ensure proper flow to the cutting zone.
