Kennametal 2238551 Replaceable-tip Drill 23.42-23.92mm 3xd

Product Description

The KENNAMETAL 2238551 is a replaceable-tip drill body from the KSEM series, engineered for high-productivity hole-making in metalworking applications. It accepts KSEM0922 insert tips at insert seat size 4, allowing quick tip changes without removing the holder from the machine spindle. The body features through-coolant capability via a 0.1378-inch coolant hole, directing fluid directly to the cutting zone to extend insert life and improve chip evacuation. The straight-cylindrical shank measures 25.40 mm in diameter and 3.0 inches in length, with an overall length of 6.88 inches. Drill depth-to-diameter ratio is 3xD, with a maximum drill depth of 70.25 mm.

This drill body is designed for CNC machining centers and turning centers in job shop, production, and heavy manufacturing environments. It handles hole diameters from 23.42 mm to 23.92 mm, making it suitable for applications requiring close-tolerance bores in steel, cast iron, stainless, and similar workpiece materials. The replaceable-tip design reduces tooling cost per hole compared to brazed or solid carbide alternatives and is typically set up and run by CNC machinists and tool-and-die professionals in both horizontal and vertical machining centers.

Installation Notes

Installation is performed by CNC machinists or toolroom personnel. Ensure the machine spindle is fully stopped and the tool is properly secured before inserting or removing the drill body from the toolholder. Seat the insert tip fully and verify torque per KENNAMETAL KSEM tooling documentation before running. Confirm through-coolant supply lines are connected and pressurized to specification before beginning the drilling cycle.
