Kennametal 6771163 Replaceable Drill Tip 0.8125 in KCP15A

Product Description

The KENNAMETAL 6771163 is a replaceable drill tip designed for use with compatible KTFSS-series modular drill bodies. Manufactured from fine-grain solid carbide and PVD-coated with AlTiN, this tip delivers controlled cutting performance in demanding drilling applications. The 180-degree flat point geometry eliminates the need for a pilot and allows flat-bottom entry and exit. The cutting diameter is 0.8125 inches (13/16 inches) with a functional length of 0.4063 inches and an overall projection of 0.4638 inches. Machinists and tooling technicians working in production or job-shop environments install this tip as a fast-swap consumable on modular drill assemblies.

This tip is suited for drilling operations in steel, stainless steel, and cast iron, corresponding to ISO material groups P, M, and K. Supported operations include standard through-hole drilling, flat-bottom drilling, inclined entry, inclined exit, and counterboring. The straight flute and straight spiral configuration with a 2-flute, 4-margin design promote chip control and stability in these materials. The tip is held in place with a clamp-style insert holding method at seat size Y. This tip does not include coolant-through capability.

Key Features

• Fine-grain solid carbide substrate for wear resistance in hard and abrasive workpiece materials
• AlTiN PVD coating improves heat resistance and tool life in steel and stainless steel cutting
• 180-degree flat point angle enables flat-bottom drilling, inclined entry, and inclined exit operations
• 2-flute, 4-margin geometry supports stable, precise hole quality in P, M, and K material groups
• Replaceable tip design reduces tooling cost compared to full-length solid drills
• Clamp-style retention at seat size Y provides rigid, repeatable tip indexing

Compatibility

Designed for use with KTFSS-series modular drill bodies accepting seat size Y replaceable tips. The ISO number for this tip is KTFSS08125FEG. Verify seat size and series compatibility with the drill body before ordering.

Installation Notes

Replaceable drill tip installation should be performed by a qualified machinist or tooling technician. De-energize and lock out the machine spindle before removing or seating any replaceable tip. Ensure the seat is clean and free of chips or debris before installing the tip, as contamination can affect runout and tip seating. Follow the drill body manufacturer's clamping torque and procedure specifications for seat size Y inserts.
