The KP-6025 washer is an OEM replacement part for the KP-60A handpiece line from KUPA. It is a thin metal washer (brass/copper alloy) that fits in the front or internal spindle assembly area of the handpiece. Its role is to provide proper spacing, alignment, and thin support in the high-speed rotating section of the tool.

Features

  • Ensures correct spacing and support within the front/spindle assembly of the handpiece, which is critical for smooth, vibration-free rotation at high RPM.

  • By using the OEM washer, you maintain proper tolerance and clearance — reducing risk of mis-alignment, bit wobble or uneven wear.

  • Because it is a small, thin part, replacing it proactively (especially if worn or deformed) is an inexpensive way to preserve overall tool performance and extend lifespan.

  • Using original KUPA-specified parts helps maintain service integrity and fitment in the precision handpiece.

  • Material: Copper/brass washer alloy (“cooper” in listing) — suited for high-speed applications.

Dimensions

  • Outside Diameter (OD): ~ 39.593 mm (≈ 1.56") (though the listing shows 39.593mm followed by “0.31"” which appears inconsistent). 

  • Inside Diameter (ID): 7.80 mm.

  • Thickness: 0.6 mm.

Installation Tips

  • Confirm that your handpiece indeed uses part #KP-6025 (check parts list or existing washer).

  • Confirm actual washer dimensions in your unit match listed spec; if internal modifications or upgrades have been made, dimensions may vary.

  • Ensure the seating surfaces where the washer will sit are clean, undamaged, and free of debris — a new thin washer in a damaged housing may not restore full performance.

  1. Unplug the handpiece and ensure it is fully stopped before disassembly.

  2. Remove the front housing or components necessary to access the washer location.

  3. Remove the old washer, clean the area of any metal shavings or lubricant residue.

  4. Insert the new KP-6025 washer ensuring it lies flat, is uncontorted, and matches the orientation of prior washer (if applicable).

  5. Re-assemble the handpiece and run it unloaded (no bit) at low speed to verify smooth rotation and minimal vibration before full use.
