25mm to 20mm Saw Blade Arbor Adapter 5pcs Set for Lapidary, Glass & Tile Saws

The 25mm to 20mm Saw Blade Arbor Adapter 5pcs Set is a precision-engineered reducing bushing kit developed to adapt diamond saw blades and cutting discs with a 25mm bore onto machinery with a 20mm arbor shaft.

Key Features

• Precision Tolerance Fit: Accurately bridges 25mm inner diameter saw blades to standard 20mm motor spindles, eliminating shaft runout, vibration, and blade wobble.
• Heavy-Duty Precision Machining: Fabricated from durable metallic alloy to withstand high rotational speeds, continuous cutting friction, and wet coolant environments.
• 5-Piece Value Multi-Pack: Supplies 5 matching adapters for mounting multiple diamond cutting discs or keeping dedicated workshop replacements.
• Cleaner Kerf Cuts: Assures true concentric blade rotation for cleaner cuts across hard agate, quartz, jasper, glass slabs, and ceramic tiles.

Recommended Applications

• Adapting 25mm bore diamond trim and slab saw blades to 20mm spindle lapidary machines and wet tile saws.
• Mounting circular stone, marble, and masonry cutting discs onto 20mm arbor power tools.
