Kennametal 2238545 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 2238545 is a replaceable-tip drill body in the KSEM series, designed for precise hole-making in metalworking and machining applications. It accepts KSEM0844 insert tips at an insert seat size 3, allowing quick tip changes without removing the body from the spindle. The drill body features a straight-cylindrical shank measuring 25.4 mm in diameter and an overall length of 6.5 inches, with through-coolant capability via a 3.50 mm coolant hole to support chip evacuation and thermal management at the cutting zone. This tool is intended for use by machinists and tool-room professionals operating CNC machining centers or manual machine tools requiring consistent, repeatable bore quality.

This replaceable-tip drill body is suited for general-purpose drilling in production and job-shop environments where tool change time and cost-per-hole are priorities. It covers a drill diameter range of 21.44 to 21.93 mm (0.8441 to 0.8634 inch) with a 3xD depth-to-diameter ratio and a maximum drill depth of 64.3 mm (2.53 inches). Typical applications include structural steel, alloy steel, cast iron, and similar workpiece materials in aerospace, automotive, and general machining contexts where KSEM-series replaceable-tip tooling is already in use.

Compatibility

Compatible with KSEM0844 replaceable insert tips at insert seat size 3. Designed for use within the KSEM series modular replaceable-tip drill platform. No additional compatible model numbers or machine pairings were specified in the product data.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and the spindle locked before seating or removing the replaceable tip. Use the appropriate KSEM torque wrench or drive key as specified by KENNAMETAL tooling documentation when securing the insert tip to the seat. Verify through-coolant passages are clear and unobstructed before resuming machining operations. Confirm shank clamping meets the machine tool manufacturer holding force requirements for the 25.4 mm straight-cylindrical shank interface.
