Kennametal 6771158 Replaceable Drill Tip 0.75in KCP15A

Product Description

The KENNAMETAL 6771158 is a replaceable drill tip in the KTFSS series, designed for use with compatible indexable drill bodies that accept a size X insert seat. The tip measures 0.75 inches in cutting diameter with a 180-degree flat point geometry and a straight flute configuration with 2 flutes and 4 margins. The solid carbide construction uses a fine-grain carbide substrate at manufacturer grade KCP15A, processed with a PVD-applied AlTiN coating. These characteristics make this tip suitable for production drilling applications where tool-change speed and consistent hole quality are priorities for machining professionals.

This replaceable drill tip is intended for drilling operations in steel, stainless steel, and cast iron workpiece materials, corresponding to ISO material codes P, M, and K. Its flat-bottom point geometry and straight flute design support flat-bottom drilling, inclined entry, inclined exit, and counterboring operations. The tip is held in place via clamp-style retention and does not include coolant-through capability. It is suited for use in CNC machining centers and production turning applications where indexable drill systems are standard.

Key Features

• 0.75-inch cutting diameter with 180-degree flat point for flat-bottom hole applications
• Solid carbide fine-grain substrate at grade KCP15A for wear resistance in ferrous materials
• PVD-applied AlTiN coating improves heat resistance during high-speed drilling
• Straight flute, 2-flute, 4-margin geometry supports accurate hole position and surface finish
• Clamp-style insert holding for secure seating and repeatable tool change
• Compatible with inclined entry, inclined exit, counterboring, and flat-bottom drilling operations

Compatibility

Designed for use with KTFSS series indexable drill bodies accepting a size X insert seat. Compatible with workpiece materials including steel, stainless steel, and cast iron (ISO P, M, and K material groups).

Installation Notes

Installation and replacement of indexable drill tips should be performed by qualified machinists following the drill body manufacturer's clamping and torque procedures. Power down and lock out the spindle before removing or seating the insert. Ensure the insert seat is clean and free of chips or debris before clamping to maintain accurate tip runout. Follow all applicable shop safety procedures when handling carbide tooling.
