Kennametal 6388795 Replaceable Drill Tip 0.5781in KCP15A

Product Description

The KENNAMETAL 6388795 is a replaceable drill tip designed for use with compatible modular drill bodies in metal-cutting operations. Manufactured from solid carbide with a fine grain material grade and KCP15A designation, this insert features a physical vapor deposition (PVD) AlTiN coating that extends tool life in demanding cutting environments. The tip measures 0.5781 inches in cutting diameter with a 180-degree included point angle and HPG insert geometry. It seats in an S-size insert seat and is held in place by a clamp-style insert holding method. Machinists and tooling technicians install this tip as a consumable replacement in production drilling applications.

This drill tip is suited for drilling steel and cast iron workpieces, including applications involving inclined exits and stacked plates. The helical flute design with a regular spiral and two-flute, two-margin configuration supports chip evacuation in these conditions. Coolant-through capability is not present on this tip, so external or flood coolant strategies are appropriate for heat management. It fits KTFSS-series modular drill bodies that accept the S seat size, making it a direct consumable replacement in existing KTFSS tooling setups.

Key Features

• Solid carbide construction with fine grain material grade for hardness and wear resistance
• AlTiN PVD coating for extended tool life in steel and cast iron cutting
• 180-degree point angle with HPG geometry for reduced thrust and clean entry
• Two-flute, two-margin helical design promotes chip flow in stacked and inclined-exit drilling
• S-seat clamp-style mounting for secure tip retention in KTFSS modular drill bodies
• Functional length of 0.2891 inches with an overall projection of 0.4139 inches

Compatibility

Designed for use with KTFSS-series modular drill bodies that accept the S insert seat size. Confirmed compatible applications include drilling of steel and cast iron, inclined-exit drilling, and stacked-plate drilling as specified in the product application data.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with modular drill systems. Ensure the spindle is stopped and the machine is locked out before replacing the drill tip. Seat the insert fully into the S-seat pocket and secure with the clamp per the drill body manufacturer torque guidance. Inspect the seating surface for chips or debris before each installation to prevent seating errors that can affect bore accuracy.
