Kennametal 6371077 Replaceable Drill Tip 0.5433 in KCMS15

Product Description

The KENNAMETAL 6371077 is a replaceable drill tip designed for use with KTFS-series modular drilling systems. It carries a cutting diameter of 0.5433 inches (13.80 mm) and is manufactured to grade KCMS15, a carbide substrate suited for demanding metal-cutting applications. The tip features an HPL insert geometry with a 140-degree included angle, and is finished with an AlTiN (aluminum titanium nitride) coating applied via PVD process. This combination of geometry and coating provides thermal resistance and wear performance in ferrous and hard materials. The tip installs into a compatible insert seat size Q holder and is intended for use by machinists and toolroom professionals working on CNC or manual drilling operations.

This replaceable drill tip is used in modular drilling applications where the tip can be swapped independently of the shank body, reducing tooling cost per hole and maintaining consistent geometry across production runs. It is suited for precision drilling in steel, stainless steel, and cast iron in both production shop and maintenance environments. The KTFS series platform it belongs to is a common choice in industrial machining where repeatable hole quality and quick tip changes are priorities.

Key Features

• Cutting diameter of 0.5433 inches (13.80 mm) for precision bore sizing
• Grade KCMS15 carbide substrate for hardness and wear resistance in metal cutting
• AlTiN coating via PVD process for thermal stability and extended tip life
• HPL insert geometry with 140-degree included angle for self-centering entry and chip control
• Insert seat size Q for compatibility with matching KTFS-series holders
• Replaceable tip design allows shank reuse, reducing per-hole tooling cost

Compatibility

Designed as a replaceable tip for KTFS-series modular drill bodies using insert seat size Q. Confirm seat size and series designation on the holder before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully de-energized and the machine is locked out before changing drill tips. Seat the tip firmly into the holder using the appropriate torque key or wrench per the holder manufacturer's assembly procedure. Inspect the seat and tip mating surfaces for chips or debris before seating to avoid runout issues.
