Hard-Wearing XD Construction with Extra Fast Cut
Featuring a compact structure of non-woven fibers coated with resin and abrasive grains, our tough Standard Abrasives Quick Change Surface Conditioning XD Disc is engineered with a stiff backing and provides high initial and extended rates of cut on extra tough surfaces. Within the Standard Abrasives line of surface conditioning discs, the XD disc is the fastest cutting and offers excellent performance on edges. It is mainly used on ferrous metals and non-loading metals of all types.

XD discs are made of a tough but flexible nylon mesh that fits any contoured surface. We designed XD material with a woven low-stretch fabric (scrim) embedded in the nylon structure to provide additional strength and durability. Moreover, we constructed the XD material with a thicker coating of resin for additional heft. The scrim and thick resin coating extend the life of the disc and allow for extended use on ferrous materials or steel. Use this disc when high contact pressure and stock removal are required, and when loading is not a concern.

Aluminum Oxide for Ferrous Metals and Composites
The fibers that make up this disc are overlaid with aluminum oxide abrasive. Aluminum oxide discs are a good match for operators who desire an all-purpose versatility and economy. The mineral cuts fast while blending and deburring and is a good choice for applications on ferrous metals and composites. XD discs feature a premium grain with higher fracture strength, meaning the mineral will fragment and renew more readily. They are available in coarse (brown) or medium (maroon) grits.

Recommended Applications
Our Surface Conditioning XD Disc features a thick coating of resin that makes it ideal for material removal where loading is not an issue. Choose this disc for use on all metals, particularly ferrous metals, for:

• Deburring: removing large and micro burrs, edge radius, removing die cast flashings
• Blending: removing mill marks, tool marks and mismatches, reducing uneven edges between adjoining surfaces, reorienting surface scratch patterns, creating a smooth transition from one surface profile to another
• Finishing: cosmetic graining, polishing welds, reducing roughness, conditioning grind lines

Quick Change Discs Boost Productivity
Quick change discs allow tool-free swap outs, maintain secure attachment at high speeds, and save operators time when switching discs between grades or applications. Easy fastening and swapping of discs enhances tool efficiency and worker productivity. The TP system features a snap-on/snap-off nylon fastening hub. TR discs have a nylon threaded male hub that easily threads onto TR type holder pads with a turn of the wrist, and the TS system has a metal hub that fastens to its holder pad with a simple twist.

Standard Abrasives™ Quick Change XD Discs are available with TP, TR and TS attachments in disc diameters up to 4. Discs with 4-1/2 to 7 diameters have a TS 5/8-11 threaded hub that easily mounts to a TS 5/8-11 holder pad. We recommend using our discs together with a Standard Abrasives™ Quick Change Holder Pad to ensure optimal disc performance and to ensure that pressure is applied evenly all the way to the edge of the disc.

Dense Material, Efficient Surface Conditioning
Surface conditioning material combines non-woven nylon fibers and aluminum oxide mineral using a resin bond to create an open web. Its resin bond tolerates heat and enhances overall abrasive durability. Moreover, gaps between the non-woven fibers allow swarf and debris to escape, prolonging abrasive service life.

Overall, surface conditioning products provide a more compact structure of non-woven fibers than Buff & Blend products. Surface Conditioning products have a woven polyester fabric (scrim) embedded in the nylon structure to provide additional strength and durability for edge work, deburring and efficient blending of all metal types. They can be washed and re-used, and may be used with lubricants.
