Frequently Asked Questions

  • Q: How do I find the right saw blade arbor bushing size for my lapidary trim saw?
    A: Measure the blade bore diameter and the saw arbor diameter. Select the washer ring that converts from your blade’s bore size down to your saw’s arbor size. Most hobby lapidary trim saws use a 5/8" arbor.
  • Q: Why is my diamond saw blade wobbling during cutting and how do I fix it?
    A: Blade wobble is caused by a loose fit between the blade bore and arbor. Use a correctly sized washer ring for a snug, play-free fit. Wobble causes uneven cutting, premature blade wear, and unsafe operating conditions.
  • Q: What arbor size do most lapidary trim saws and slab saws use?
    A: Most hobby lapidary trim saws use a 5/8" arbor. Larger slab saws typically use 3/4", 1", 20mm, or 25mm arbors. Our washer ring collection covers all common sizes from 1/2" through 32mm in 18 conversion combinations.
  • Q: Can I use saw blade washer rings with tile saw blades and angle grinder cutting discs?
    A: Yes — compatible with diamond saw blades, tile saw blades, marble blades, and angle grinder discs. Match the washer ring to convert your blade bore to your tool’s arbor diameter.
