3M™ 3” Bumpon Cushions 3-pack

3M™ 3” Bumpon Cushions 3-pack
Mount these Cushion Pads onto the 3 inch Backpads for a smoother grind & a refined polish. Recommended for fine grade abrasives such as 220 grit and finer. Their flexibility helps sand and polish contours of rounded and domed workpieces and gives them a shock-absorption effect as well.

Simply stick them onto the Backpad before applying an Abrasive. They come in 3 flexibility options: Bumpon™, Medium-Flex and Soft-Flex.

– The 3M™ Bumpon™ (Black color) cushions are great for working on lapidary with Diamond Abrasives or sharpening rounded edges on tools with Trizact abrasives.

– Use the Medium-Flex (White color) when working on domed/rounded Polymer Clay, Ice Resin, Amber, and other soft materials. We recommend these abrasives: Microfinishing Film, Polishing Film and WetOrDry Polishing Abrasives.

– Use the Soft-Flex cushions (White color) when working on very soft and very rounded pieces made with Polymer Clay, Ice Resin, Amber, or other soft materials. We also recommend these abrasives: Microfinishing Film, Polishing Film and WetOrDry Polishing Abrasives..
