Kennametal 6389338 Indexable Drill Body Kentip Fs 3xd

Product Description

The KENNAMETAL 6389338 is a straight-shank indexable drill body from the KenTIP FS series, designed for high-productivity drilling operations on machining centers and CNC turning equipment. The body accepts interchangeable KenTIP FS drill tips, allowing fast tip changes without removing the holder from the spindle. Key specifications include a 1.0000-inch straight cylindrical shank, a 3xD drill depth-to-diameter ratio, and through-coolant capability with an overall length of 164 mm. This tool body is installed by machinists and tooling setup technicians in production and job-shop environments where consistent hole quality and cycle-time efficiency are required.

The 6389338 is suited for drilling operations in ferrous and non-ferrous materials across a range of industries including aerospace, automotive, and general metalworking. The 3xD depth ratio makes it appropriate for through-hole and moderate-depth blind-hole applications. The straight cylindrical shank interfaces with standard ER collet chucks, hydraulic chucks, and shrink-fit holders that accept a 1-inch shank. The KenTIP FS toolholder style (KTFS) is specific to the KenTIP FS insert tip system. The flute length is 94.50 mm and the shank length is 56.00 mm.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or lockout-tagout state before mounting or removing the drill body. Confirm the holding device is properly torqued to the chuck or collet manufacturer specification before running. Verify through-coolant passages are clear and coolant pressure is appropriate for the application before the first cut.
