Kennametal 1528347 Indexable Insert Drill 31.8mm 2.5xd

Product Description

The KENNAMETAL 1528347 is a DFT-series indexable insert drill designed for general-purpose drilling in metal cutting applications. It accepts two DFT-style inserts and delivers a maximum drill depth of 79.5mm (3.13 inches) with a depth-to-diameter ratio of 2.5xD. The 31.8mm nominal body diameter reaches a maximum drill diameter of 33.66mm (1.325 inches). The 1-1/4 inch Weldon Flat and Flange shank provides secure, repeatable tool holding in compatible spindles. Coolant-through capability is built in via axial concentric entry, supporting higher cutting speeds and chip evacuation. Licensed HVAC and metalworking trade shops will recognize this as a production-grade drilling tool built for rigidity and insert indexability.

This drill body is suited for production drilling operations in machining centers and CNC lathes where repeatable hole diameter and depth are critical. The DFT insert system and 2.5xD depth ratio make it appropriate for through-holes and blind holes in steel, cast iron, and similar workpiece materials in both job-shop and high-volume environments. The right-hand cutting direction and Weldon Flat shank suit vertical and horizontal machining center setups. Compatible insert size code is DFT05T3, and the body accepts two inserts simultaneously for balanced cutting geometry.

Key Features

• DFT-series insert compatibility with insert size code DFT05T3 and insert dimensions of 5.29mm x 3.75mm (0.208 x 0.148 inches)
• 2.5xD drill depth-to-diameter ratio with a maximum drill depth range of 75mm to 100mm (3.0 to 4.0 inches)
• Coolant-through design with axial concentric entry, body side coolant hole thread size 1/8-27, and shank end coolant hole thread size 1/4-18
• 1-1/4 inch Weldon Flat and Flange shank for positive drive and precise radial location
• Steel tool body construction with right-hand cutting direction and two-insert configuration
• Overall length of 8.0 inches with a body length of 4.75 inches and shank length of 3.25 inches

Compatibility

Compatible with DFT-style inserts, insert size code DFT05T3, and insert lock screw M3-0.5x7.2 T9. Designed for use in machine spindles that accept a 1-1/4 inch Weldon Flat and Flange straight shank. No additional compatible model numbers or system families were specified in the available product data.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and in a safe, locked-out state. Follow the machine tool manufacturer torque specifications for Weldon Flat set screws and insert lock screws. Verify coolant port connections before operation to confirm through-coolant flow is active. Dispose of or recycle worn inserts per applicable shop safety and environmental guidelines.
