Kennametal 6388575 Carbide Replaceable Tip Drill 45/64 in

Product Description

The KENNAMETAL 6388575 is a carbide replaceable tip drill insert designed for use with compatible KTFS-series drill bodies. The insert carries the ISO designation KTFSS07031HPG and is manufactured in grade KCP15A using fine-grain solid carbide with a PVD-applied AlTiN coating. It produces a cutting diameter of 0.7031 inches (45/64 inches) and is engineered with an HPG insert geometry for improved chip control and edge stability during drilling operations. The clamp-style holding method secures the insert firmly in the seat. This part is installed by machinists and tool-crib technicians in production and job-shop environments.

This insert is suited for drilling applications in steel and cast iron workpieces, corresponding to ISO material codes P and K. The HPG geometry and AlTiN coating support use in inclined-exit drilling, stacked-plate drilling, and standard through-hole operations. The 2-flute, 2-margin, regular-spiral helical flute design promotes chip evacuation in these demanding setups. No internal coolant delivery is provided through this insert, so external coolant or flood delivery should be planned accordingly.

Key Features

• Solid carbide KCP15A fine-grain substrate with PVD AlTiN coating for wear resistance in ferrous materials
• HPG insert geometry provides controlled cutting action and margin support
• 0.7031 inch (45/64 inch) cutting diameter, clamp-mounted in KTFS series insert seat size V
• 2-flute, 2-margin, regular-spiral helical flute configuration for chip evacuation
• Rated for inclined-exit, stacked-plate, and standard drilling applications
• No coolant-through design - external or flood coolant required for optimal performance

Compatibility

Designed as a replaceable tip insert for KENNAMETAL KTFS-series drill bodies accepting insert seat size V. ISO designation KTFSS07031HPG. Verify seat size and clamping compatibility with the specific drill body before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the machine tool and toolholder manufacturer guidelines. Ensure the machine spindle is fully stopped and the machine is locked out before seating or removing the insert. Use the correct torque driver or clamp screw specified by the drill body manufacturer - do not over-torque the clamp screw, as this can damage the insert seat. Confirm correct seating and clamping before resuming cutting operations.
