Kennametal 2238541 Replaceable-tip Drill 19.46-19.96mm

Product Description

The KENNAMETAL 2238541 is a replaceable-tip drill body in the KSEM series, designed for precision hole-making in metalworking applications. It accepts KSEM0766 insert tips at seat size 2, allowing fast tip changes without removing the body from the spindle. The drill covers a diameter range of 19.46 to 19.96 mm (0.7661 to 0.7858 inches) and achieves a maximum drill depth of 58.34 mm (2.30 inches) at a 3xD depth-to-diameter ratio. Overall length is 6.25 inches. Through-coolant delivery via a 3.50 mm (0.1378-inch) coolant hole supports chip evacuation and tool life at elevated cutting speeds. This body is installed and serviced by machinists and CNC tool-setup technicians.

The 2238541 is suited for production drilling in CNC machining centers and turning centers where repeatable hole diameter and depth are required. The straight-cylindrical shank measures 25.40 mm in diameter and 76.20 mm (3.00 inches) in length, fitting standard toolholders used in horizontal and vertical machining center setups. The 3xD depth ratio makes it appropriate for through-holes and blind-hole applications in medium-depth drilling operations on steel, cast iron, and similar workpiece materials common in general metalworking and heavy manufacturing environments.

Compatibility

Designed for use with KSEM0766 replaceable insert tips at insert seat size 2 within the KSEM series drill body platform.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or removing the replaceable insert tip. Confirm the toolholder bore matches the 25.40 mm straight-cylindrical shank diameter and that coolant ports are aligned and unobstructed before operation. Follow the machine tool manufacturer and KENNAMETAL torque and clamping guidelines for the insert seat; do not overtighten the tip-retention screw with non-specified tools.
