Sander Sanding Discs | 125mm 8-Hole Pattern | For Wood & Metal Grinding

These 125mm sanding discs for woodworking fit your random orbital disc sander. They use a tough aluminum oxide abrasive that works on both wood and metal. The 8-hole pattern helps clear dust, keeping your workspace cleaner. Features and Benefits - Grit Assortment - You get coarse (40), medium (1000), and fine (2000) grits for all steps, from stripping to finishing. - Aluminum Oxide Abrasive - This hard mineral cuts steadily on hardwood and soft metals without getting dull fast. - 8-Hole Dust Extraction - The holes line up with most 125mm sanders to pull dust away, which makes the disc last longer. - Hook and Loop Backing - The 5-inch hook and loop design lets you change sanding pads in seconds without tools. Applications - Fine Woodworking - Use fine grits to get a smooth surface on furniture and cabinets, ready for stain. - Paint and Varnish Removal - Quickly take off old finishes from wood surfaces with the lower, more aggressive grits. - Metal Preparation - Smooth out welds or remove light rust from metal before painting. Ray L. Carter (Stationary/Industrial Disc Sander) While the exact inventor of the disc sander is debated, early designs like those patented by Ray L. Carter in the late 19th century laid the groundwork for modern machines. These stationary disc sanders, often running at speeds like 1725 rpm, are commonly used for tasks such as shaping wood and metal grinding. The 125mm sanding discs with an 8-hole pattern are suitable for these machines, allowing for effective dust extraction and efficient material removal. A range of grits, including 40, is available for aggressive work. Alex A. Clarke (Portable Specialty Sanders) Alex A. Clarke also contributed to the development of sanding technology, with patents for portable sanding machines. A disc sander is a power tool that uses an abrasive disc to sand surfaces. These portable versions are ideal for more specific applications, such as intricate woodworking or polishing. The 125mm diameter and 8-hole pattern of these sanding discs ensure compatibility with many such portable sanders. For fine finishing, grits like 1000 and 2000 are essential for achieving a smooth surface on wood or metal. Arthur N. Emmons (Modern Portable Handheld Disc Sander) Modern portable handheld disc sanders benefit from the innovations of inventors like Arthur N. Emmons. These tools are versatile for both woodworking and metal grinding, and are often used for preparing surfaces or removing old finishes. The 125mm 8-hole pattern sanding discs are a standard fit, providing good dust extraction for a cleaner work environment. With a range of grits from 40 for heavy removal to 2000 for polishing, these discs are suitable for various applications a tradesperson might encounter.
