Kennametal 6371086 Replaceable Drill Tip 14.00mm KCMS15

Product Description

The KENNAMETAL 6371086 is a replaceable drill tip designed for use with KTFST-series modular drill bodies. The tip measures 0.5709 inches (14.50 mm) in cutting diameter with a 140-degree point angle and a functional length of 0.2855 inches. It is manufactured from solid carbide with a fine grain material grade and carries a PVD-applied AlTiN coating for thermal and wear resistance. The HPL insert geometry and helical flute design support chip evacuation in demanding materials. Coolant-through capability delivers cutting fluid directly to the cutting edge. This tip is installed and replaced by machinists and tool crib technicians as part of a modular drilling system.

This replaceable tip is suited for drilling operations in stainless steel and other M-group workpiece materials. The two-flute, two-margin configuration supports drilling on inclined exit surfaces and through stacked plates, making it applicable in aerospace, energy, and general metalworking operations. The clamp-based insert holding method allows quick tip changes without removing the drill body from the spindle. The S-seat size designates the correct mating drill body required for this tip.

Key Features

• Solid carbide construction with fine grain material grade for edge strength and wear resistance
• PVD AlTiN coating improves performance in stainless steel and high-temperature alloys
• 140-degree point angle with HPL geometry reduces thrust force and improves centering
• Coolant-through design delivers fluid directly to the cutting edge for chip flushing and heat control
• Two-flute helical design supports inclined exit drilling and stacked-plate applications
• Clamp-held replaceable tip allows fast changeover without removing the drill body

Compatibility

Designed for use with KTFST-series modular drill bodies requiring an S-seat insert. The ISO number for this tip is KTFST14500HPLM. Verify seat size and series compatibility with the drill body before ordering.

Installation Notes

Installation and replacement of this tip should be performed by qualified machinists following the drill body manufacturer torque and seating procedures. Ensure the spindle is stopped and the machine is in a safe, locked-out state before handling the tip. Inspect the insert seat for chips or debris before seating the new tip. Do not force the tip into the seat; proper seating is confirmed by full contact with the seat face before clamping.
