Kennametal 6771155 Replaceable Drill Tip 18mm KCP15A Carbide

Product Description

The KENNAMETAL 6771155 is a replaceable drill tip designed for use with compatible modular drill bodies in precision metal-cutting applications. Built from fine-grain solid carbide in manufacturer grade KCP15A, this tip features a 180-degree flat point geometry and a physical vapor deposition (PVD)-applied AlTiN coating for heat and wear resistance at the cutting edge. The insert geometry is FEG with a straight flute and straight spiral configuration, and it is held in place by a clamp-style insert seat size W. Cutting diameter is 18.00 mm (0.7087 inches), with a functional length of 0.3544 inches and an overall length of 0.4064 inches. This tip is installed by machinists and tooling technicians working in production and job-shop environments.

This 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. Supported operations include standard drilling, flat-bottom drilling, inclined entry and exit drilling, and counterboring. It carries two flutes and four margins without coolant-through capability, making it suited for applications where through-coolant is not required or available. The KTFSS series tip format is a common modular indexable drill platform used in CNC machining centers and lathes handling medium-to-large diameter hole-making operations.

Key Features

• Fine-grain solid carbide construction in grade KCP15A for consistent edge integrity in ferrous materials
• AlTiN coating applied via PVD process for elevated temperature resistance and extended tool life
• 180-degree flat point angle enables flat-bottom drilling and reliable inclined-entry performance
• FEG insert geometry with 2-flute and 4-margin configuration for chip control and hole quality
• Seat size W with clamp-style holding method for secure, repeatable tip indexing
• Compatible with inclined entry, inclined exit, flat-bottom, and counterboring operations

Compatibility

This tip is designed for use with KTFSS series modular drill bodies accepting an 18.00 mm seat size W replaceable tip. Specific compatible drill body part numbers were not provided in the available product data; consult KENNAMETAL tooling documentation to confirm body compatibility before ordering.

Installation Notes

Replaceable drill tips of this type are installed and indexed by qualified tooling technicians or machinists. The machine spindle must be fully stopped and the tool assembly secured before removing or seating the tip. Use the correct torque tool or wrench specified by the drill body manufacturer for the clamp screw — do not over-tighten by hand or with unapproved tools. Inspect the insert seat for chips, debris, or damage before seating a new tip to ensure proper location and clamping force.
