Scotch-Brite 15914 HS-DR Series High Strength Disc, 3 in, Medium Grade, Aluminum Oxide, Maroon

The Scotch-Brite™ Roloc™ high strength disc features our durable, tough, open web material and delivers professional results for deburring, creating satin finishes and cleaning. Its conformability allows it to work well on flat or irregular surfaces without damaging or altering the dimensions the base material. Scotch-Brite™ non-woven fibers provide cool, uniform wear and the open web construction resists loading. Designed for our 3M™ Roloc™ quick change attachment system, the no-hole center on some versions allows use of more of the disc surface as well as quick and easy disc change out. These attributes combine to provide consistent finishing over the life of the disc.
3M Scotch-Brite non-woven HS-DR quick change disc uses aluminum oxide as the abrasive material and has a diameter of 3 in. Since this product is non-woven, grade is generally used to describe the abrasiveness; with the 15914 having a medium grade. All abrasive products that rotate or spin, such as the ones in this category, have a maximum speed at which you can run them. This 3M quick change disc can be run at a maximum speed of 12000 RPMs.

Maximum RPM:
The maximum rotations per minute (RPM) a product is designed to be used at should be respected for the sake of safety and use life. Maximum RPM is provided for all product listings where applicable and is often printed on the item in the case of discs and wheels. Operating a wheel above its maximum recommended speed can cause a wheel to crack or even shatter.
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.
Quick Change Type:
Quick change attachments allow discs to be switched easily while providing a more stable grip than hook and loop or PSA attachments. Quick change discs are designed to fit disc holders with one of these main types: Type I (Type P or TP) - snap on/off Type II (Type TS, TSM, or S) - female threaded twist on/off Type III (TR or R) - male threaded roll on/off TN - Disc has its own 5/8-11 inch threaded mounting nut and can be mounted directly on a tool with the proper backup accessory
Abrasive Material:
Values: A/O Aluminum Oxide AO A/Z Alumina Zirconia AZ S/C Silicon Carbide SC Alumina Zirconia 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 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. Felt 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. Zirconia Zirconium
