3M 7000046846 | 840032 Standard Abrasives 3/4" Diameter Medium Aluminum Oxide Quick Change Surface Conditioning FE Disc

The Standard Abrasives Quick change surface conditioning FE disc saves time preparing workpieces for final finishes and coatings by performing one-step prep work. A reliable choice for edgework, some of its best uses include deburring and blending. FE material is an outstanding performer for flats and edgework when high contact pressure and stock removal are required.

Featuring a more compact structure of non-woven fibers than buff & blend products, the Standard Abrasives Quick change surface conditioning FE disc is engineered to provide high initial and extended rates of cut, while maintaining edge durability. Constructed of resin-reinforced, non-woven fiber, this disc is aggressive yet minimizes under-cutting or gouging of the workpiece. Within the Standard Abrasives line of surface conditioning discs, the FE disc performs the best on edges.

Standard Abrasives FE Surface conditioning discs are made of a tough but flexible nylon mesh that fits any contoured surface. The FE material is designed with a woven fabric (scrim) embedded in the nylon structure to provide additional strength and durability. This helps extend the life of the disc and allows for prolonged use on ferrous materials or steel. This is the best surface conditioning material to use when high contact pressure and stock removal are required, and when loading is not a concern.

Choose a Standard Abrasives Surface conditioning disc for use on ferrous metals, stainless steel, and high nickel/chrome alloys to perform:

• Deburring: Removing large and micro burrs, edge radiusing, 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

Surface conditioning products have a non-woven construction in which fiber strands, resin, and abrasive mineral form a thick, open web or mesh. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils and contaminants while maintaining the geometry of the workpiece, which in turn reduces rework and boosts productivity. Gaps in the web allow heat and swarf to escape, prolonging the performance of the abrasive. Fibers in the web continually break down with use to reveal fresh mineral for exceptional consistency, superior cut performance and extremely long service life.

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. FE discs feature a premium grain with higher fracture strength, meaning the mineral will fragment and renew more readily. They are available in coarse (brown), medium (maroon), and very fine (blue) grits.

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 or 3M Roloc 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 FE 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. It is recommend using these 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.

The Standard Abrasives brand has supplied quality abrasives to the metalworking industry for over 50 years. Customers rely on a broad offering of high performance products including coated, bonded, and non-woven abrasive lines.
