Kennametal 1522130 Indexable Insert Drill 4xd 26.2mm

Product Description

The KENNAMETAL 1522130 is a DFT-series indexable insert drill designed for productive hole-making in metalworking applications. The body accepts two DFT05T3 inserts and delivers a maximum drill depth of 104.78mm (4.125 inches) at a 4xD depth-to-diameter ratio. The nominal drill diameter is 26.2mm, with a maximum drill diameter capacity of 29.37mm (1.156 inches). The 1.25-inch straight shank features a Weldon flat and flange configuration for positive torque transfer in standard milling machine and machining center spindles. Axial concentric coolant entry and a through-coolant design support chip evacuation and cutting edge life at higher feed rates. Overall tool length is 9 inches. The tool body is constructed from steel.

This drill is suited for general-purpose drilling operations in production and job-shop environments on machining centers, CNC lathes, and drill presses equipped with a 1.25-inch tool holder. The DFT insert platform and right-hand cutting geometry make it a standard choice for through-hole and blind-hole applications in carbon steel, alloy steel, and similar workpiece materials. Installed by machinists and tool-room technicians, it fits operations requiring consistent, repeatable hole quality in the 4xD depth range.

Key Features

• DFT series body accepts two DFT05T3 indexable inserts for cost-effective edge replacement without regrinding
• 4xD depth-to-diameter ratio with 104.78mm maximum drill depth
• Weldon flat and flange straight shank (1.25-inch diameter) for positive drive and runout control
• Axial concentric coolant-through design supports chip flushing at depth
• Right-hand cutting direction compatible with standard spindle rotation
• Steel tool body construction for rigidity in general-purpose drilling

Compatibility

Compatible with DFT insert style, specifically DFT05T3 inserts (insert size 5.29mm x 3.75mm). Shank end coolant hole thread size is 1/4-18. Insert lock screw specification is M3-0.5x7.2 T9 drive. Designed for use in tool holders accepting a 1.25-inch straight shank with Weldon flat and flange interface.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle and coolant supply are fully de-energized and locked out before mounting or removing the tool body or inserts. Secure the shank in a properly sized Weldon-style holder and confirm axial coolant port alignment before operation. Always inspect insert seating and lock screw engagement before running the tool; use the specified T9 torx driver for the M3-0.5 insert lock screw and do not substitute driver sizes.
