Kennametal 1517238 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 1517238 is a replaceable-tip drill body designed for deep-hole drilling in metalworking applications. It accepts KSEM0625 insert tips and is built to the KSEM series standard, offering a drill depth-to-diameter ratio of 8xD. The 19.05 mm Weldon Flat shank provides positive rotational drive in compatible tool holders, while through-coolant delivery via 1/8-27 NPT ports at both the body side and shank end keeps cutting edges cool and evacuates chips effectively. Overall length is 209.55 mm with a flute length of 143.04 mm. Licensed machinists and toolroom technicians install this body as part of a modular drilling system on CNC machining centers and lathes with live tooling.

This drill body is suited for medium-to-deep hole applications in ferrous and non-ferrous workpiece materials where consistent, repeatable hole diameter is required. The replaceable-tip design allows the cutting insert to be indexed or swapped without removing the drill body from the spindle, reducing downtime in production environments. It handles a drilling depth range of 125 mm to 160 mm, placing it in a versatile range for structural components, mold work, and general machining. The Weldon Flat shank seats in standard side-lock holders commonly found on vertical machining centers and horizontal boring mills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer or turret is in a safe, locked position before handling the drill body. Confirm through-coolant supply connections match the 1/8-27 NPT thread specification at both coolant ports before pressurizing the system. Torque the insert tip per the KENNAMETAL KSEM assembly documentation supplied with the insert, and verify runout with a dial indicator before commencing production drilling.
