Saw Blade Arbor Adapters

Precision-machined arbor adapters and bore reducer bushings for lapidary saw blades. Engineered to convert blade arbor hole diameters to match your saw's arbor shaft, ensuring concentric mounting, zero slippage, and smooth, vibration-free stone cutting. Compatible with trim saws, slab saws, and tile saws operating diamond blades from 4" to 24" in diameter.

Adapter & Bushing Sizing Guide

Blade Bore (Outer Diameter) Saw Shaft (Inner Diameter) Compatible Saw Types Application Notes
1" (25.4mm) 5/8" (15.87mm) Trim saws, 6"–10" slab saws Most common lapidary adapter size combination
1" (25.4mm) 3/4" (19.05mm) Mid-size 10"–14" slab saws Standard fitment for heavy-duty hobby slab saws
1-1/4" (31.75mm) 1" (25.4mm) Large 16"–24" slab saws Commercial and industrial lapidary slab saws
20mm 5/8" (15.87mm) Metric blade on imperial arbor Metric-to-imperial saw arbor conversion

Key Advantages

  • CNC-machined from high-grade aluminum or brass for precise concentricity
  • Prevents blade runout, wobble, and premature diamond rim dislodgement
  • Flush-fit thickness matches blade core plate without flange interference
  • Corrosion-resistant materials withstand water, oil, and mineral coolant cutting

Frequently Asked Questions

  • Q: How do I choose the correct arbor adapter?
    A: Measure the center hole diameter of your diamond blade (which determines the adapter's outer diameter) and your saw motor's arbor shaft diameter (which determines the adapter's inner bore). Select the bushing matching both dimensions precisely.
  • Q: Are arbor reducer bushings safe for high-RPM operation?
    A: Yes, precision-machined adapters are designed for continuous cutting speeds when properly seated within the blade hole and clamped securely between saw flanges. Never stack multiple thin bushings together on a single shaft.
  • Q: Can I use an arbor adapter if the bushing is thicker than my blade?
    A: No. The adapter must be flush with or slightly thinner than the blade core. If the bushing is thicker than the blade, the saw flanges will clamp against the bushing instead of the blade, preventing proper drive torque transmission.
