Kennametal 6388765 Carbide Replaceable Tip Drill 17/32 in

Product Description

The KENNAMETAL 6388765 is a carbide replaceable tip drill insert built to the KTFSS series specification under manufacturer part number KTFSS05312HPG, grade KCP15A. It features a 17/32 inch (0.5312 inch) cutting diameter, solid carbide construction with fine grain material grade, and an AlTiN PVD coating for wear resistance and thermal stability at elevated cutting speeds. The HPG insert geometry and P seat size are designed to deliver consistent chip control and accurate hole quality. This replaceable tip format reduces tooling cost by allowing tip replacement without discarding the full drill body. Licensed machinists and tool-and-die professionals are the primary installers.

This drill tip is suited for production drilling operations in steel and cast iron workpiece materials, matching ISO material groups P and K. Typical applications include through-hole and blind-hole drilling in general machining environments. The tip is rated for drilling inclined exits, stacked plates, and standard straight-entry holes, making it a versatile insert for job shops and high-mix manufacturing cells that require reliable tool change cycles. The 2-flute, 2-margin helical flute design supports regular spiral chip evacuation in ferrous materials.

Key Features

• Solid carbide fine grain substrate for toughness and edge stability in ferrous materials
• AlTiN PVD coating for heat and wear resistance at higher surface footage
• HPG insert geometry for consistent chip formation and hole quality
• 2-flute, 2-margin helical design supports clean chip evacuation without coolant through
• Rated for inclined exit drilling and stacked plate applications
• Replaceable tip design minimizes downtime and reduces per-hole tooling cost

Compatibility

Designed for use with KTFSS series replaceable tip drill bodies accepting P seat inserts. Primary workpiece materials are steel and cast iron (ISO material groups P and K). Confirm body seat size P and KTFSS series compatibility before ordering.

Installation Notes

Installation and tip changes should be performed by qualified machinists following the machine tool manufacturer's lockout/tagout procedure before any tooling interchange. Use the specified torque wrench and clamp screw recommended by Kennametal for the P seat to avoid seat damage or tip misalignment. Do not exceed the cutting parameters published in Kennametal's application data for grade KCP15A in the target material. Inspect the insert seat for wear, chips, or debris before seating a new tip to ensure proper contact and runout.
