Kennametal 1246034 Replaceable-tip Drill 22.5-23mm

Product Description

The KENNAMETAL 1246034 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. It accepts KSEM2250 series insert tips at an Insert Seat Size 4, allowing the body to be reused while only the cutting tip is replaced. The drill covers a diameter range of 22.5 mm to 23 mm (0.8858 to 0.9055 inches) and reaches a maximum drilling depth of 72 mm (2.835 inches). Overall length is 161 mm (6.339 inches). Through-coolant delivery via a 3.5 mm (0.1378 inch) coolant hole keeps the cutting zone clear and extends insert life during deep-hole operations. This tool is installed by machining professionals in production and job-shop environments.

The 1246034 is suited for drilling operations requiring a 3xD depth-to-diameter ratio in steel, cast iron, and similar workpiece materials. The 25 mm whistle notch shank provides positive, slip-resistant seating in compatible tool holders on CNC machining centers and turning centers. The 100 mm flute length and 56 mm shank length are optimized for chip evacuation at full depth. This body is part of the KSEM platform, which standardizes insert indexing across a range of drill diameters for shops running multiple hole sizes.

Compatibility

Designed for use with KSEM2250 series replaceable insert tips at Insert Seat Size 4, within the KENNAMETAL KSEM platform. Requires a tool holder with a 25 mm whistle notch bore.

Installation Notes

Installation and insert indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or replacing the insert tip. Ensure the whistle notch shank is fully engaged and properly torqued in the tool holder per the machine tool manufacturer specifications. Verify through-coolant supply lines are clear and coolant pressure is set per shop standards before initiating a cut.
