Kennametal 2238534 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 2238534 is a KSEM-series replaceable-tip drill designed for precision hole-making in metal cutting applications. The body accepts KSEM0688 inserts at insert seat size 1, allowing tip replacement without discarding the drill body. The straight-cylindrical shank measures 19.05 mm in diameter and 50.80 mm in length, and the overall length is 4.88 inches. Through-coolant delivery via a 3.50 mm coolant hole supports chip evacuation and heat management at the cutting zone. This tool is installed and operated by machinists and CNC tooling technicians on machining centers and drill presses requiring repeatable, tight-tolerance bore diameters.

This drill body is suited for production drilling in ferrous and non-ferrous materials where a depth-to-diameter ratio of 3xD is appropriate. Maximum drill depth reaches 52.39 mm, with a depth range of 40.00 mm to 60.00 mm. The replaceable-tip design is common in high-volume job shop and manufacturing environments where insert indexing reduces downtime compared to regrinding solid carbide drills. The straight-cylindrical shank interfaces directly with standard drill chucks, hydraulic chucks, and shrink-fit toolholders sized for 19.05 mm shanks.

Key Features

• 3xD depth-to-diameter ratio with a maximum drill depth of 52.39 mm (2.06 inches)
• Straight-cylindrical shank at 19.05 mm diameter is compatible with standard CNC toolholding systems
• Overall length of 4.88 inches with a flute length of 2.72 inches for reach in typical machining setups

Compatibility

Compatible with KSEM0688 insert style at insert seat size 1. Part of the KSEM series drill body platform. Designed for use in machining centers and drill presses equipped with toolholders accepting a 19.05 mm straight-cylindrical shank.

Installation Notes

Installation and tool changes should be performed by qualified machinists or CNC tooling technicians with the machine in a fully stopped and locked-out state. Ensure the toolholder bore is clean and free of debris before seating the shank, and verify insert seating and clamping torque per the toolholder manufacturer's specifications. Through-coolant connections must be confirmed leak-free before resuming cutting operations. Follow the machine tool manufacturer's guidelines for spindle speed and feed rate when using replaceable-tip drill bodies of this type.
