Kennametal 6388746 Replaceable Drill Tip 13mm KCP15A

Product Description

The KENNAMETAL 6388746 is a solid carbide replaceable drill tip designed for use in modular drilling systems. It features a 13.00 mm (0.5039 inch) cutting diameter, a 180-degree point angle, and an AlTiN coating applied via PVD process. The tip carries the ISO designation KTFSS12800HPGM and is graded KCP15A in a fine grain carbide substrate. With an HPG insert geometry and helical flute design, this tip delivers consistent cutting performance in demanding hole-making applications. It is intended for installation by machinists and tooling technicians using compatible modular drill bodies.

This replaceable drill tip is suited for drilling steel and cast iron workpieces, with primary workpiece material codes P and K. It supports drilling on inclined exits and stacked plates, making it appropriate for setups where entry and exit conditions are less than ideal. The two-flute, two-margin configuration without coolant-through capability is suited for operations where external or flood coolant is applied. The tip mounts using a clamp-style insert holding method and fits an O-series insert seat size.

Key Features

• Solid carbide construction in fine grain substrate for wear resistance in steel and cast iron
• AlTiN coating via PVD process for improved heat resistance and tool life
• 180-degree point angle with HPG insert geometry for accurate entry and exit
• Helical flute, regular spiral design promotes chip evacuation
• Rated for inclined exit and stacked plate drilling applications
• Clamp-style retention in O-seat insert pocket for secure, repeatable positioning

Compatibility

Designed for use in KENNAMETAL KTFSS-series modular drill bodies that accept an O-seat replaceable tip insert. Verify seat size and series designation on the drill body before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing or seating the drill tip. Clean the insert pocket and seating surfaces before installation to prevent runout errors. Follow the drill body manufacturer torque specifications for the clamping screw — do not over-torque, as this can damage the carbide tip or the seat.
