Kennametal 1522127 Indexable Insert Drill 4xd 1.0626 in

Product Description

The KENNAMETAL 1522127 is a DFT-series indexable insert drill designed for through-coolant drilling operations in metal cutting applications. It accepts two DFT-style inserts and drills to a maximum depth of 4.25 inches at a 4xD depth-to-diameter ratio. The body diameter measures 1.0626 inches with a maximum drill diameter of 1.188 inches, and the overall length is 9.125 inches. The steel body features a Weldon Flat and Flange shank with a 1.25-inch shank diameter. Axial concentric coolant entry keeps the cutting zone clear during deep-hole operations. This tool is installed and used by machinists and CNC operators in production and job-shop environments.

This drill is suited for general-purpose drilling in ferrous and non-ferrous materials where indexable insert tooling is preferred over solid-carbide drills. The 4xD ratio makes it appropriate for moderate-depth holes in workpieces such as flanges, housings, manifolds, and structural components. The straight shank with Weldon Flat and Flange interface mounts directly into compatible drill chucks or collet holders on machining centers and CNC lathes.

Key Features

• DFT-series drill body accepts two DFT05T3 indexable inserts for fast insert changes without removing the body from the spindle
• 4xD depth-to-diameter ratio supports maximum drill depth of 4.25 inches
• Axial concentric coolant-through entry (1/4-18 shank end thread) delivers coolant directly to the cutting edges
• Weldon Flat and Flange shank (1.25 inches diameter) provides positive drive and precise runout control
• Right-hand cutting direction; compatible insert size code DFT05T3, insert lock screw M3-0.5x7.2 T9 Torx
• Steel body construction for rigidity and durability in general-purpose drilling applications

Compatibility

Compatible with DFT-style indexable inserts, insert style code DFT05T3, insert size 0.208 x 0.148 inches (5.29 x 3.75 mm). Insert lock screw specification is M3-0.5x7.2 T9. Designed for use in machine spindles accepting a 1.25-inch straight shank with Weldon Flat and Flange interface.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before mounting or removing the drill body. Verify coolant-through connections at the shank end are properly sealed and pressurized to the machine tool specification before commencing drilling. Inspect insert seating and confirm the M3 lock screw is torqued per KENNAMETAL tooling guidelines before each use; never run the tool with a loose or missing insert.
