CMT Calibration and Sanding Disk - 8 inch x 5/8 inch Bore by CMT is a precision dual-purpose accessory designed for stationary table saw use. This 8-inch sanding and calibration disk serves two distinct roles in the workshop: it functions as a fence alignment tool for accurate table saw calibration, and it handles light sanding operations on hardwood, softwood, and MDF. With a 5/8 inch bore diameter and a precisely milled plate thickness of 0.110 inch, this disk delivers consistent, repeatable results on both calibration tasks and surface finishing work.

Key Features

• Dual-function design for calibration and sanding - handles fence alignment checks and light sanding in one tool, reducing the need for multiple accessories in your workshop setup.
• 8 inch (200mm) disk diameter - provides a broad working surface suited to stationary table saw spindles, making it effective for both fence calibration sweeps and sanding passes.
• 5/8 inch (15.87mm) bore diameter - fits the standard 5/8 inch arbor found on most stationary table saws, allowing straightforward mounting without adapters.
• 0.110 inch plate thickness - a consistent, controlled thickness ensures the disk runs true on the arbor, which is critical for accurate fence calibration results and smooth sanding performance.
• Compatible with hardwood, softwood, and MDF - versatile material compatibility means this disk handles a wide range of common woodworking materials found in both professional shops and home workshops.

Why This Product

• If your table saw fence drifts out of alignment, this disk gives you a reliable, flat reference surface to check and correct that alignment quickly - without sourcing a separate calibration tool.
• The 5/8 inch bore fits directly onto the standard table saw arbor, making installation straightforward with no special adapters or hardware required.
• The controlled 0.110 inch plate thickness means the disk runs with minimal runout, giving you accurate calibration readings and consistent sanding results across hardwood, softwood, and MDF workpieces.
• Combining fence calibration and light sanding capability in a single 8-inch disk keeps your tool inventory leaner and your workflow more efficient during table saw setup and finishing operations.
