Kennametal 6388595 Replaceable Tip Drill 47/64 in KCP15A

Product Description

The KENNAMETAL 6388595 is a carbide replaceable tip drill insert designed for use with compatible KTFSS-series drill bodies. Identified by ISO number KTFSS07344HPG and manufactured to grade KCP15A, this solid carbide tip features a Physical Vapor Deposition (PVD) AlTiN coating applied over a fine-grain carbide substrate. The insert delivers a cutting diameter of 0.7344 inches (47/64 inches) with an HPG insert geometry and is held in place via a clamp-style seat size W. With 2 flutes in a regular helical spiral, it is suited for high-productivity drilling operations in steel and cast iron. Licensed HVAC and plumbing trades do not install this part; it is used by machining and metalworking professionals.

This replaceable tip drill insert is designed for drilling operations in steel (ISO material code P) and cast iron (ISO material code K). Approved applications include standard drilling, inclined-exit drilling, and stacked-plate drilling. The 2-flute, 2-margin, no-coolant-through configuration makes it suitable for setups where internal coolant supply is not available. It fits KTFSS-series replaceable tip drill bodies that accept a size W insert seat.

Key Features

• Solid carbide construction with fine-grain material grade for edge integrity
• KCP15A manufacturer grade with PVD AlTiN coating for wear resistance in steel and cast iron
• HPG insert geometry optimized for chip control during drilling
• 2-flute, regular helical spiral design supports inclined-exit and stacked-plate applications
• Clamp-style insert holding method with size W seat for secure seating in KTFSS bodies
• No internal coolant-through requirement simplifies setup

Compatibility

Designed for use with KTFSS-series replaceable tip drill bodies accepting a size W insert seat. Compatible primary workpiece materials are steel (P) and cast iron (K) as specified by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC or manual drilling equipment. Power down and lock out the machine before seating or removing the insert. Use the appropriate torque wrench and manufacturer-recommended clamp hardware when securing the insert to the drill body; do not overtighten by hand estimation. Verify insert seating and runout before beginning any cutting operation.
