Kennametal 6388568 Replaceable Drill Tip 17mm KCP15A

Product Description

The KENNAMETAL 6388568 is a replaceable drill tip designed for indexable drilling systems where consistent hole quality and fast tip changes are required. Built from solid carbide with a fine grain structure and a KCP15A grade designation, this tip features a physical vapor deposition (PVD) AlTiN coating for extended tool life in demanding cutting conditions. The 180-degree point angle delivers flat-entry cutting geometry, and the HPG insert geometry supports stable chip formation. With a cutting diameter of 0.6890 inches (17.00 mm) and a functional length of 0.3445 inches, this tip fits KTFSS-series drill bodies using an insert seat size V. Installation is performed by machinists and toolroom technicians on CNC machining centers and drill presses.

This replaceable tip is suited for production drilling in steel and cast iron workpieces, covering ISO material groups P and K. The helical, 2-flute, 2-margin design without through-coolant supports general-purpose drilling operations. Specific applications include drilling on inclined exit surfaces and stacked plate configurations, making it a practical choice for structural, fabrication, and precision machining environments where repeatable diameter and position accuracy are critical.

Key Features

• Solid carbide construction with fine grain material grade for edge strength and wear resistance
• AlTiN coating applied via PVD process for thermal protection and extended tool life in steel and cast iron
• 180-degree included angle for flat-entry drilling geometry
• HPG insert geometry with regular spiral and 2-flute, 2-margin configuration for stable chip evacuation
• Clamp-held mounting in KTFSS-series seat size V drill bodies
• Rated for inclined exit and stacked plate drilling applications

Compatibility

Designed for use with KTFSS-series indexable drill bodies accepting insert seat size V. Compatible with the ISO designation KTFSS17500HPGM. Intended for drilling steel and cast iron workpieces in ISO material groups P and K.

Installation Notes

Replaceable drill tips of this type are installed and changed by qualified machinists or toolroom personnel. Power down and de-energize the machine spindle before seating or removing the tip. Use the correct clamping torque tool as specified by the drill body manufacturer - do not overtighten or substitute fasteners. Verify seat cleanliness and tip seating before resuming cutting operations.
