Kennametal 2238550 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 2238550 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. It accepts KSEM0906 insert tips and operates across a diameter range of 23.01 to 23.52 mm (0.9059 to 0.9260 inches), reaching a maximum drill depth of 69.06 mm (2.72 inches) at a 3xD depth-to-diameter ratio. The tool features a 25.4 mm straight-cylindrical shank and an overall length of 6.75 inches. Through-coolant capability is built in via a 3.50 mm coolant hole, supporting chip evacuation and thermal management at the cutting zone. Machinists and CNC operators in production and job-shop environments are the primary users of this tool body.

This drill body is suited for use in CNC machining centers and turning centers where consistent, repeatable hole diameters in the 23 mm range are required. The KSEM series platform is built around indexable replaceable tips, allowing the cutting edge to be swapped without removing the body from the spindle. This makes it a practical choice for high-volume drilling operations in steel, cast iron, and similar ferrous workpiece materials where tool change time and consistency are critical.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle should be powered down and locked out before mounting or removing the drill body from the tool holder. Confirm shank fit and clamping torque per machine tool manufacturer specifications before operation. Verify coolant-through passages are clear and coolant pressure is within machine specifications before beginning any drilling cycle.
