Kennametal 6688273 Kentip Fs Indexable Drill Body

Product Description

The KENNAMETAL 6688273 is a straight-shank indexable drill body from the KenTIP FS series, designed for use with interchangeable carbide drill tips in high-production machining environments. The body features a 1/2-inch straight-cylindrical shank and a drill depth-to-diameter ratio of 3xD, making it well suited for moderate-depth hole applications. Through-coolant capability is built in, supporting effective chip evacuation and tool life in demanding cutting conditions. The KTFS toolholder style is consistent with KenTIP FS tip compatibility. Machinists and tooling specialists in metalworking and precision manufacturing install this drill body on CNC machining centers and lathes with live tooling.

This drill body is intended for use in production drilling operations where indexable tip tooling is preferred over solid carbide or brazed-tip drills. The straight-cylindrical shank fits standard ER and hydraulic chucks as well as shrink-fit holders that accommodate 1/2-inch shanks. The 3xD depth ratio is typical for through-hole and blind-hole applications in materials such as steel, cast iron, and aluminum alloys. It is a component of the broader KenTIP FS modular drilling platform.

Installation Notes

Installation is performed by tooling technicians or machinists on CNC machining centers or live-tool lathes. Power down and lock out the spindle before tip exchange or body installation. Ensure the shank seating surface and collet bore are clean and free of chips before clamping. Follow the machine tool and toolholder manufacturer torque guidelines for pull-stud and clamping nut retention.
