This washer (Part #520K22) is a high-precision, OEM-grade replacement component designed specifically for the KP-55 line of handpieces. It is engineered to provide accurate spacing and alignment within the front housing or spindle assembly of the tool—ensuring smooth, vibration-free operation under high-speed conditions.

Features

  • Exact OEM specification for KP-55 models: Outside Diameter: 12.34 mm, Inside Diameter: 10.75 mm, Thickness: 3.99 mm. 

  • Material: Copper, rated for high-speed use in professional nail-drill handpieces. 

  • Designed to maintain proper clearance, prevent axial or radial play, and sustain alignment in the KP-55’s rotating assembly.

Installation Tips

  • Confirm your existing spacer/washer's dimensions match the listed spec (ID 10.75 mm / OD 12.34 mm / thickness 3.99 mm).

  • Ensure the seating surfaces (housing, spindle nose, bearing area) are clean, free from debris, metal shavings, or damage — because even a correctly sized washer will not perform properly if its seat is compromised.

  • Unplug and stop the handpiece before disassembly.

  • Remove the front housing or collet assembly to access the washer location.

  • Remove the old washer, clean the area thoroughly.

  • Insert the new 520K22 washer so it seats fully, flat, and aligned.

  • Re-assemble and run a no-load test to verify smooth rotation and absence of vibration or unwanted movement.
