3M Bristle Disc for Metal Finishing
The 3M 61500129830 bristle disc is a finishing accessory designed for use with straight grinders, drill presses and pencil grinders. It targets metalworkers who need to clean or deburr aluminium, brass, bronze, cast iron, stainless steel and steel surfaces.
Quick-Change Mount Installs in Seconds
The disc uses a TR quick-change connector that locks onto compatible tools without extra hardware. The ceramic bristles are rated for a maximum operating speed of 30,000 RPM; exceeding this limit is the most common cause of premature wear or bristle loss.
Ideal for Light Deburring on Hard Metals
This P50 grit disc suits shops that need a green, 1-inch diameter cup brush with 5/8-inch trim for general finishing tasks. It is not intended for heavy stock removal, aggressive grinding or applications that demand a coarser grit or larger brush diameter.
