Kennametal 2238555 Replaceable-tip Drill 1 in Ksem Series

Product Description

The KENNAMETAL 2238555 is a replaceable-tip drill body in the KSEM series, designed for precision hole-making in metal cutting applications. It accepts KSEM1000 insert tips at an insert seat size 5, allowing tip replacement without removing the holder from the machine. The drill body covers a diameter range of 1.0000 to 1.0197 inches (25.40 to 25.90 mm) with a maximum drill depth of 3.0000 inches (76.20 mm), yielding a 3xD depth-to-diameter ratio. Overall length is 7.13 inches. Through-coolant capability is built in, with coolant holes measuring 0.1575 inches (4.00 mm) in diameter to direct fluid directly to the cutting zone. Licensed machinists and CNC operators install this tool in production machining centers.

This drill body suits CNC vertical and horizontal machining centers performing production drilling in steel, cast iron, and other metallic workpiece materials. The straight-cylindrical shank diameter of 25.40 mm (1.0000 inches) and shank length of 3.0000 inches (76.20 mm) are sized for standard toolholders and collet chucks compatible with that shank diameter. The KSEM series is suited for high-volume, repeatable drilling cycles where consistent hole diameter and depth accuracy are required across large part runs.

Key Features

• Replaceable KSEM1000 insert tip at seat size 5 - extend tool life without replacing the entire body
• Through-coolant design with 0.1575-inch coolant holes directs fluid to the cutting edge for chip evacuation and heat control
• 3xD depth-to-diameter ratio supports drilling to 3.0000 inches depth in a single pass
• Straight-cylindrical shank at 25.40 mm suits standard CNC toolholders and collet systems
• Diameter range of 1.0000 to 1.0197 inches accommodates KSEM1000 tip variants within that range
• Flute length of 3.97 inches provides adequate chip clearance for the full depth range

Compatibility

Designed for use with KSEM1000 series replaceable insert tips at insert seat size 5. Part of the KSEM drill body series by KENNAMETAL.

Installation Notes

Installation is performed by qualified machinists or CNC tooling setup technicians. Confirm machine spindle is fully stopped and locked out before changing insert tips or seating the tool body in the holder. Seat the straight-cylindrical shank to the full recommended grip length in the toolholder and torque the clamping mechanism per the toolholder manufacturer specifications. Verify coolant ports are clear and aligned with the machine spindle coolant supply before running the spindle.
