Product Description

The KENNAMETAL 6389425 is an indexable drill body designed for use with the KenTIP FS insert system. It features a straight cylindrical shank with a 3/8 inch diameter and a 5xD drill depth-to-diameter ratio, making it suitable for deep-hole drilling operations where consistent bore quality and insert interchangeability are required. The overall length is 104 millimeters, with a flute length of 61.20 millimeters and a shank length of 40.39 millimeters. This drill body is intended for use by machinists and tool and die professionals working with indexable insert drilling systems in CNC and manual machining environments.

This drill body is suited for production drilling applications in metal fabrication, general machining, and industrial manufacturing. The KTFS toolholder style integrates with KenTIP FS series replaceable drill tips, allowing the body to be reused while tips are swapped out at wear intervals. It is appropriate for use on CNC machining centers and turning centers where straight-shank tooling is compatible with the machine spindle or toolholder interface.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable insert tooling systems. Secure the shank properly in a collet or toolholder that accommodates a 3/8 inch straight cylindrical shank, ensuring adequate clamping force per the machine manufacturer's specifications. Before changing tips or servicing the drill body, confirm the machine spindle is fully stopped and locked out according to applicable machine safety procedures. Do not exceed the recommended drill depth or feed rates specified in the KenTIP FS application guidelines for the selected insert tip.
