Kennametal 6371018 Replaceable Drill Tip 9mm 140 Deg KCMS15

Product Description

The KENNAMETAL 6371018 is a replaceable drill tip designed for use with KTFST-series modular drilling systems. It features a 0.3504 inch (9.00 mm) cutting diameter, a 140-degree drill point angle, and is manufactured from solid carbide with a fine grain substrate. The tip carries the KCMS15 grade designation and is coated with AlTiN via a PVD process, providing heat resistance and wear life in demanding cutting applications. Two helical flutes and integrated coolant-through channels support chip evacuation and thermal management at the cutting zone. This tip is installed and replaced by machinists and tool-room technicians as part of a quick-change drilling setup.

This replaceable tip is suited for drilling operations in stainless steel and similar ISO M-group workpiece materials. The HPL insert geometry, standard point type, and regular spiral configuration support applications including straight drilling, inclined exit drilling, and stacked plate drilling. Insert seat size G matches the corresponding KTFST holder body. The coolant-through design makes it appropriate for deep-hole and high-feed drilling cycles where flood coolant alone is insufficient for chip removal.

Key Features

• 9.00 mm (0.3504 inch) cutting diameter with 140-degree included point angle
• Solid carbide fine grain substrate for edge stability in hard and abrasive materials
• AlTiN coating applied by PVD process for oxidation and heat resistance
• Coolant-through channels deliver cutting fluid directly to the tip for chip flushing
• HPL insert geometry with 2-flute, 2-margin configuration for controlled cutting action
• Clamp-style insert holding method for secure seating in KTFST holder bodies

Compatibility

Designed for use with KTFST-series modular drill holders accepting insert seat size G. ISO number KTFST08900HPLM identifies this tip within the KTFST modular drilling platform.

Installation Notes

Replaceable drill tips of this type are installed and serviced by machinists following machine lockout and spindle-stop procedures. Seat surfaces on both the tip and holder body should be inspected and cleaned before seating to ensure full contact and accurate runout. Follow the tool holder manufacturer torque guidelines for the clamping screw - do not use impact tools. Confirm coolant-through passages are clear and unobstructed before returning the assembly to service.
