Kennametal 1528341 Indexable Insert Drill 27mm 2.5xd

Product Description

The KENNAMETAL 1528341 is a 27mm diameter indexable insert drill designed for general-purpose drilling operations in metal and industrial materials. Built to a 2.5xD depth-to-diameter ratio, it achieves a maximum drill depth of 2.65 inches using two DFT-style replaceable inserts. The body is constructed of steel and features a 1-1/4 inch (1.2500 inch decimal) Weldon Flat and Flange shank for secure toolholder engagement. Coolant-through capability via axial concentric entry supports chip evacuation and tool life in production environments. This drill is suited for machinists and tooling specialists working on CNC machining centers and production drilling setups.

The 1528341 fits applications requiring consistent, repeatable hole quality in a general-purpose drilling context. The right-hand cutting direction and straight Weldon Flat shank make it compatible with standard milling and drilling machine toolholders. The 7-3/8 inch overall length accommodates typical spindle clearance in vertical and horizontal machining centers. It is well suited for job shops, production floors, and maintenance machining where indexable tooling reduces regrind downtime and maintains hole diameter consistency across high-volume runs.

Key Features

• 27mm drill diameter with 1.1870 inch maximum drill diameter capability
• 2.5xD depth-to-diameter ratio with 2.65 inch maximum drill depth
• Takes two DFT05T3 indexable inserts for fast on-machine insert changes
• Coolant-through design with axial concentric entry for effective chip clearance
• Weldon Flat and Flange shank provides positive drive and minimal runout
• Steel body construction for rigidity in demanding drilling applications

Compatibility

Compatible with DFT-style indexable drill inserts, insert size code 05T3, specifically DFT05T3 inserts. Insert lock screw specification is M3-0.5x7.2 T9. Body side coolant hole thread size is 1/8-27 inch; shank end coolant hole thread size is 1/4-18 inch.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body from the toolholder. Verify the Weldon Flat set screw engagement and coolant line connections before initiating a cut. Follow the machine tool manufacturer guidelines for recommended spindle speeds and feeds for indexable insert drills of this diameter.
