5/8" (15.875mm) to 1/2" (12.7mm) Saw Blade Arbor Adapter 5pcs Set for Lapidary, Glass & Tile Saws

The 5/8" (15.875mm) to 1/2" (12.7mm) Saw Blade Arbor Adapter 5pcs Set is a precision-machined reducing bushing kit designed to adapt diamond saw blades and cutting discs with a 5/8" (15.875mm) bore onto machines and motors equipped with a 1/2" (12.7mm) arbor spindle.

Key Features

• Precision Tolerance Fit: Accurately bridges 5/8" (15.875mm) inner diameter saw blades to standard 1/2" (12.7mm) motor shafts, preventing blade wobble, vibration, and arbor runout.
• Heavy-Duty Precision Machining: Machined from durable wear-resistant metal alloy to maintain strict concentricity under wet cutting friction and high rotational speeds.
• 5-Piece Value Multi-Pack: Provides 5 matching reducer bushings, perfect for mounting multiple diamond blades or keeping reliable backups in the workshop.
• Clean & Accurate Kerf: Eliminates arbor slippage for smooth, chip-free cuts across agate, jasper, jade, glass slabs, and porcelain tile.

Recommended Applications

• Mounting 5/8" arbor diamond trim saw and lapidary slabbing blades onto 1/2" shaft grinding arbors or tile saws.
• Adapting circular masonry, ceramic, and gemstone cutting wheels to bench motors with a 1/2" arbor spindle.

Installation & Operating Guidelines

• Clean both the blade core arbor opening and motor spindle prior to mounting.
• Press the adapter bushing squarely into the 5/8" blade hole until flush on both sides.
• Mount the blade and adapter onto the 1/2" shaft, position outer stabilizing flanges, and tighten the arbor nut securely.
• Always operate lapidary sawing machinery with adequate coolant and eye protection.
