22.22mm (7/8") to 1/2" (12.7mm) Saw Blade Arbor Adapter 5pcs Set for Lapidary, Glass & Tile Saws

The 22.22mm (7/8") to 1/2" (12.7mm) Saw Blade Arbor Adapter 5pcs Set is a precision-engineered reducing bushing kit developed to adapt diamond saw blades and cutting discs with a 22.22mm (7/8") bore onto machinery with a 1/2" (12.7mm) arbor shaft.

Key Features

• Precision Tolerance Fit: Accurately bridges 22.22mm (7/8") inner diameter saw blades to standard 1/2" (12.7mm) 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 22.22mm (7/8") bore diamond trim and slab saw blades to 1/2" spindle lapidary machines and wet tile saws.
• Mounting circular stone, marble, and masonry cutting discs onto standard 1/2" arbor power tools.

Installation & Operating Guidelines

• Clean the blade mounting area and arbor shaft thoroughly before installation.
• Press the adapter ring evenly into the 22.22mm arbor hole until completely flush with both sides of the blade core.
• Slide onto the 1/2" shaft, secure with flanking arbor flanges, and torque the arbor nut firmly.
• Always operate lapidary saws with proper coolant lubrication and eye protection.
