Kennametal 1522133 Indexable Insert Drill 4xd 25.4mm

Product Description

The KENNAMETAL 1522133 is a DFT-series indexable insert drill designed for general-purpose drilling in metal-cutting applications. It accepts two DFT05T3 indexable inserts and delivers a 4xD depth-to-diameter ratio, reaching a maximum drill depth of 101.6mm (4 inches) in a single pass. The tool body is machined from steel with a 25.4mm (1 inch) straight shank featuring a Weldon flat and flange for positive drive retention. Coolant is delivered axially through a concentric internal channel, with a 1/4-18 threaded entry at the shank end. This drill is installed and serviced by machinists and toolroom professionals on CNC machining centers and manual drilling equipment.

The 1522133 is suited for through-hole and blind-hole drilling in production and job-shop environments where repeatable hole diameter and depth are required. The right-hand cutting direction and general-purpose performance rating make it a practical choice for a wide range of workpiece materials. Overall length is 8.625 inches, with a flute length of 4 inches and a shank length of 3 inches. The maximum achievable drill diameter with appropriate inserts is 28.58mm (1.125 inches).

Key Features

• 4xD depth-to-diameter ratio supports drill depths from 100mm to 150mm (4 to 5 inches) depending on insert selection
• Accepts two DFT05T3 indexable inserts - inserts are replaceable without replacing the tool body
• Axial concentric coolant-through design directs coolant directly to the cutting zone
• Weldon flat and flange shank provides secure, anti-rotation clamping in standard Weldon-style holders
• Steel tool body construction for rigidity in high-feed drilling operations
• Right-hand cutting direction compatible with standard spindle rotation on most machining centers

Compatibility

Compatible with DFT drill style tooling and DFT05T3 series indexable inserts. Insert lock screw size is M3-0.5x7.2 T9 torx drive. Designed for use in Weldon flat shank tool holders with a 1 inch bore. Coolant entry thread at the shank end accepts a 1/4-18 fitting.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the tool body or changing inserts. Verify holder bore diameter and clamping screw engagement against the Weldon flat before operation. Do not exceed the insert manufacturer's recommended feed and speed parameters for the workpiece material.
