Kennametal 6388755 Replaceable Drill Tip 0.5197 in KCP15A

Product Description

The KENNAMETAL 6388755 is a replaceable drill tip designed for use with KTFSS-series indexable drill bodies. It features a 0.5197-inch (13.00 mm) cutting diameter, a 180-degree included point angle, and a solid carbide construction with a fine grain material grade. The AlTiN coating is applied via PVD process, improving heat and wear resistance during high-feed drilling operations. The tip uses an HPG insert geometry and mounts with a clamp-style holding method into a size-P insert seat. This tip is installed by machinists and toolroom professionals working in production drilling environments where replaceable-tip drills reduce downtime compared to solid regrindable tools.

This drill tip is suited for drilling operations in steel and cast iron workpieces, covering ISO material groups P and K. It supports helical, two-flute, two-margin geometry with a regular spiral and a standard point type. Typical applications include through-drilling, inclined-exit drilling, and stacked-plate drilling. The tip does not include through-coolant capability, making it appropriate for external coolant or flood-cooled setups. It is sized for light-duty to medium-duty drilling passes where controlled chip evacuation and edge stability in ferrous materials are priorities.

Key Features

• Solid carbide construction with fine grain material grade for edge stability in ferrous materials
• AlTiN coating via PVD process for improved heat and abrasion resistance
• 180-degree point angle with HPG insert geometry for stable entry and reduced thrust force
• Two-flute, two-margin helical design supports controlled chip evacuation
• Clamp-style holding method with size-P insert seat for secure, repeatable tip seating
• Compatible with inclined-exit and stacked-plate drilling applications

Compatibility

Designed for use with KTFSS-series indexable drill bodies requiring a size-P insert seat. ISO number KTFSS13200HPGM identifies the tip geometry within the KTFSS platform.

Installation Notes

Replaceable drill tips of this type are installed and replaced by machinists or toolroom personnel on CNC machining centers or drill presses. Power down and lock out the spindle before seating or removing the tip. Use the correct clamp torque tool as specified by the drill body manufacturer — do not overtighten or substitute fasteners. Inspect the insert seat for chips or contamination before seating the new tip to ensure proper contact and runout.
