Walter 5656226 Replaceable Drill Tip 1.063 in WMP35 Tialn

Product Description

The WALTER 5656226 is a replaceable drill tip designed for use with P6003-series indexable drill bodies. It carries a cutting diameter of 1.0630 inches (27.00 mm) and a 140-degree included point angle, making it well suited for controlled entry and exit in difficult-to-machine materials. The tip is manufactured from solid carbide and finished with a PVD-applied TiAlN coating, which provides thermal resistance and wear life in high-temperature cutting environments. Grade WMP35 targets superalloys and titanium as primary workpiece materials, with steel and stainless steel listed as secondary applications. Insert seat size is H, and the tip is held in place with a clamp-type insert holding method.

This drill tip fits into the P6003 indexable drill platform and is intended for machining operations on superalloys, titanium, steel, and stainless steel. Typical applications include aerospace component machining, structural fabrication, and precision manufacturing where tool change speed and consistent hole geometry matter. The helical flute design with regular spiral promotes chip evacuation during through-hole and blind-hole drilling. Coolant-through capability is not included in this tip design, so external coolant or mist delivery should be planned accordingly.

Key Features

• Solid carbide construction for rigidity and heat resistance in difficult materials
• TiAlN coating applied via PVD process for extended tool life in superalloy and titanium cutting
• 140-degree point angle reduces entry force and improves positioning accuracy
• Grade WMP35 optimized for superalloys and titanium as primary workpiece materials
• Helical flute with regular spiral promotes consistent chip flow
• Clamp-type insert holding method for secure seating in P6003 drill body

Compatibility

Designed for use with WALTER P6003-series indexable drill bodies using insert seat size H. The ISO designation for this tip is P6003-D27,00R WMP35. Verify seat size and series compatibility with the host drill body before installation.

Installation Notes

Replaceable drill tips of this type are installed and removed by machinists or tool-room technicians using the appropriate clamping hardware specified by the drill body manufacturer. Ensure the spindle is fully stopped and the machine is locked out before changing drill tips. Clean the insert seat thoroughly before seating the new tip to prevent seating errors that affect hole diameter and position. Follow the torque and clamping procedure specified in the P6003 drill body documentation, as no torque values are provided with this tip alone.
