CMT Calibration and Sanding Disk - 10 inch x 5/8 inch Bore is a precision dual-purpose accessory from CMT designed for stationary table saw use. Whether you need to dial in your table saw fence alignment or perform light surface finishing on hardwood, softwood, or MDF, this 10-inch sanding and calibration disk delivers reliable results in a single tool. With a 250mm outer diameter and a 15.87mm (5/8 inch) bore, it mounts directly to standard table saw arbors, making fence calibration and abrasive sanding operations straightforward and efficient.

Key Features

• Dual-function design serving as both a calibration tool and a sanding disk - eliminates the need for separate accessories when setting fence alignment and performing light sanding on the same machine.
• 10 inch (250mm) diameter - matches the standard blade size on most 10-inch stationary table saws, so the disk installs on the arbor exactly as a blade would, with no additional adapters required.
• 5/8 inch (15.87mm) bore - fits the standard table saw arbor diameter used on the majority of stationary saws, ensuring a secure, centered mount during both calibration and sanding tasks.
• 0.110 inch plate thickness - provides the rigid, stable platform needed for accurate fence calibration, so fence adjustments are based on a true reference surface rather than a flexible one.
• Compatible with hardwood, softwood, and MDF - broadens the range of light sanding applications that can be performed without switching to a dedicated sanding setup.

Why This Product

• A single disk that serves two distinct roles - fence calibration and surface sanding - means fewer accessories to manage and a faster workflow when transitioning between setup and finishing tasks on a table saw.
• The 10-inch diameter and 5/8-inch bore match the standard arbor and blade size of most stationary table saws, so there is no guesswork about compatibility - it installs in the same position as your regular blade.
• With a precise 0.110-inch plate thickness, the disk provides a consistent, rigid reference surface that makes fence alignment more accurate compared to improvised calibration methods.
• Material compatibility with hardwood, softwood, and MDF means the disk can handle the range of stock most commonly run on a stationary table saw, making it a practical everyday shop tool rather than a single-use specialty item.

Frequently Asked Questions

What machines is this calibration and sanding disk designed for?

This disk is designed for use on stationary table saws. It installs on the standard arbor in place of a blade, making it suitable for fence calibration and light sanding operations on table saw setups with a 5/8-inch arbor.

How does this disk help with table saw fence calibration?

The disk mounts to the table saw arbor just like a blade. Its rigid 0.110-inch plate thickness provides a true, flat reference surface that you can use to set and verify the fence parallel to the blade path, giving you a more reliable alignment reference than a standard saw blade.

Can this disk be used for sanding as well as calibration?

Yes. The disk is designed for dual use - it functions both as a calibration reference tool for fence alignment and as a sanding disk for light finishing work on hardwood, softwood, and MDF on a stationary table saw.

What is the bore size of this disk, and will it fit my table saw arbor?

The bore diameter is 15.87mm, which corresponds to a 5/8-inch arbor - the standard arbor size found on most 10-inch stationary table saws. If your saw uses a 5/8-inch arbor, this disk should be a direct fit.
