Kennametal 2238544 Replaceable-tip Drill Ksem Series 3xd

Product Description

The KENNAMETAL 2238544 is a replaceable-tip drill from the KSEM series, designed for precision hole-making in metalworking and machining applications. It covers a drill diameter range of 0.8126 to 0.8323 inches (20.64 to 21.14 mm) and achieves a maximum drill depth of 2.44 inches (61.91 mm), representing a 3xD depth-to-diameter ratio. The body features a straight-cylindrical shank measuring 1.0 inch (25.40 mm) in diameter and 3.0 inches (76.20 mm) in length. An integrated through-coolant system with 0.1378-inch (3.50 mm) coolant holes keeps cutting temperatures in check during extended production runs. This tool is installed and changed out by CNC machinists and tooling specialists in job shops, production machining cells, and manufacturing facilities.

The 2238544 body is used in CNC machining centers and drill presses where repeatable, close-tolerance bores are required. Its replaceable-tip design allows the cutting insert to be swapped at the machine without removing the body from the spindle, reducing downtime in high-volume production environments. The tool accepts KSEM0813 series inserts at an Insert Seat Size 3, making insert selection and ordering straightforward for shops already running the KSEM platform.

Compatibility

Compatible with KSEM0813 series replaceable drill tip inserts at Insert Seat Size 3. Designed as an OEM-style KSEM series drill body for use in CNC machining centers and drill presses accepting a 25.40 mm straight-cylindrical shank.

Installation Notes

Installation and insert changes should be performed by qualified CNC machinists or toolroom personnel with the machine in a locked-out, zero-energy state per OSHA lockout-tagout procedures. Ensure the shank seating surface and spindle bore are clean and free of chips before mounting. Torque the replaceable tip insert according to the insert manufacturer documentation supplied with the KSEM0813 inserts. Verify coolant line connections are secure and that through-coolant flow is confirmed before initiating a cutting cycle.
