3M 01377 255L Series Dust Free Abrasive Disc Roll, 6 in Dia, P240 Grit, PSA, Gold

Our 3M™ Stikit™ gold film abrasive disc roll 255L features a single roll tear-off disc format and Stikit™ adhesive attachment, making it fast and easy-to-use. Aluminum oxide mineral abrasive with film backing balances aggressive cut with a consistent finish. Anti-loading coating and available seven-hole pattern help clear dust from the disc surface for longer life. M™ Stikit™ gold film abrasive disc roll 255L is packaged as multiple adhesive backed discs rolled onto a core. These discs tear-off conveniently one at a time for speed and efficiency and they require no liners which saves material costs. 3M™ Stikit™ discs come ready to use with a pressure sensitive adhesive coating on the backs - simply press the disc onto the backup pad and you're ready to go. They remove just as cleanly, leaving an uncontaminated surface for the next disc. We recommend using Stikit™ discs with 3M™ Stikit™ disc pads.
3M Stikit coated 255L PSA disc roll uses aluminum oxide as the abrasive material and has a diameter of 6 in. 3M incorporates this aluminum oxide material into the PSA disc roll forming a grit of P240. To aid in dust control, this product is designed to work with vacuum systems and comes with 6 holes built into the PSA Disc Roll.

Abrasive Material:
Values: A/O Aluminum Oxide AO A/Z Alumina Zirconia AZ S/C Silicon Carbide SC Alumina Zirconia Alumina zirconia is very dense and can be used under high temperatures for heavy-duty stock removal, wood planing, and grinding of fiberglass and plastics. The abrasive grain is designed to fracture during use so that it maintains sharpness. Aluminum Oxide Aluminum oxide is an artificial abrasive suited for general purpose stock removal and finishing. It is the mostly commonly used abrasive and can be used for most steels and ferrous alloys. Aluminum oxide is slightly softer but tougher than silicon carbide. Ceramic Ceramic is used for aggressive cutting and grinding of stainless steel, titanium, and metal alloys. The abrasive grain is designed to fracture during use so that it maintains sharpness. Ceramic Aluminum Oxide Cerium Oxide Diamond Diamond can be either natural or manufactured and is one of the hardest abrasive materials. It is commonly used for grinding and polishing stone and very hard steels, and for sharpening other cutting tools. Mesh Silicon Carbide Silicon carbide is a manufactured material that is extremely hard but brittle. It is commonly used for fast cutting under light pressure, particularly on cast iron, nonferrous metals, and materials such as glass and plastic. Precision Shaped Ceramic Grain Zirconia
Grit:
Grit is a measurement of the size of abrasive particles embedded in coated abrasives. The most common standards for grit size are the United States CAMI (Coated Abrasive Manufacturers Institute) and the European FEPA (Federation of European Producers of Abrasives). A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work. Grit is generally a unitless measure but is sometimes measured in microns.
Number of Vacuum Holes:
Some sanding discs have a pattern or 5, 6, or 8 vacuum holes, or even a pattern of many smaller holes, to allow a power tool to minimize dust created during operation. Reduced dust can keep the abrasive grains on a disc from clogging and thus can improve disc life. Note that sanding disc backing pads are also sold with the standard hole configurations and should match the sanding disc if they are used.
Grade:
Grade is a measurement of the size of abrasive particles embedded in coated abrasives. It is a more general measurement of the level of precision, and corresponds roughly to grit. A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work.
