Kennametal 2238563 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 2238563 is a replaceable-tip drill body from the KSEM series, designed for precision hole-making in metalworking and machining applications. It accepts KSEM1125 insert tips at insert seat size 7, allowing fast tip changes without removing the body from the spindle. The drill covers a diameter range of 28.58 to 29.08 mm (1.1252 to 1.1449 inches) and achieves a maximum drill depth of 85.73 mm (3.38 inches), representing a 3xD depth-to-diameter ratio. Through-coolant capability is built in, supporting high-speed production drilling. Machinists and CNC operators in job shops and production facilities are the primary users of this tooling.

This drill body fits standard straight-cylindrical toolholders with a 31.75 mm shank diameter. It is suited for drilling operations in steel, cast iron, and similar machinable materials on CNC machining centers and turning centers. The 3xD depth ratio makes it appropriate for through-holes and moderate-depth blind holes in a wide range of part families. The replaceable-tip design reduces per-hole tooling cost compared to solid carbide drills of equivalent diameter.

Compatibility

Designed for use with KSEM1125 series replaceable insert tips at insert seat size 7. The body uses a straight-cylindrical shank and is compatible with standard machine toolholders accepting a 31.75 mm shank diameter. No other specific model or system compatibility was stated in available product data.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or CNC tooling technician following the machine tool manufacturer lockout and power-down procedures before any toolholder work is performed. Ensure the insert seat is clean and free of chips or debris before seating a new KSEM1125 tip. Confirm that coolant lines and through-spindle coolant pressure are appropriate for the machine before operation. Follow the toolholder manufacturer torque guidelines for retention screws; do not rely on feel alone.
