Walter 6838222 Replaceable Tip Drill 28.5mm P6005 WKK45C

Product Description

The WALTER 6838222 is a replaceable tip drill in the P6005 series, designed for precision hole-making in metal-cutting applications. It features a solid carbide tip in grade WKK45C with a multilayer PVD coating - TiAlN, TiSiAlCrN, and TiSiN - that delivers heat resistance and wear life across demanding cutting conditions. The cutting diameter is 28.5mm (1.1024 inches), and the drill point is ground to a 140-degree included angle with a standard point type. A helical, regular-spiral flute configuration and a clamp-style insert holding method keep the tip secure during high-feed operations. This tool is installed by machinists and tooling technicians in production and job-shop environments.

The P6005-series replaceable tip drill is intended for use on CNC machining centers and turning centers where repeatable hole geometry and tool changeover speed are priorities. The WKK45C grade is rated for primary use in steel (ISO material code P, grade P45) and secondary use in cast iron (ISO material code K, grade K45). The J-size insert seat and ISO part number P6005-D28,50R identify the correct replacement tip for this body. Coolant-through capability is not included in this configuration.

Key Features

• Solid carbide tip in WKK45C grade for steel and cast iron cutting
• Multilayer PVD coating: TiAlN, TiSiAlCrN, and TiSiN for elevated wear resistance
• 140-degree included angle with standard point geometry for accurate entry
• Helical regular-spiral flute with clamp-style tip retention
• J-size insert seat - matches P6005 series replacement tips
• Conforms to ANSI and ISO standards

Compatibility

Designed for use with P6005 series replaceable tip drill bodies and J-seat tip inserts. The ISO number P6005-D28,50R WKK45C identifies the exact replacement tip specification for this tool. Rated for steel (P45) and cast iron (K45) workpiece materials per ISO material classification.

Installation Notes

Replaceable tip drills of this type are serviced by machinists or tooling technicians on CNC equipment. Power down and lock out the machine spindle before removing or seating the carbide tip. Use the appropriate torque key for the clamp screw - refer to the WALTER P6005 series tooling manual for the correct procedure. Inspect the insert seat for chips or debris before seating a new tip to ensure proper contact and runout.
