Great product, fast delivery. Highly recommend Benchmark products!!

These are awesome for fine detail work. They are best at about 12000 rpms, so use them on grinders that can be slowed. Otherwise, the plastic quick screw breaks off and the wheel goes sailing. Be gentle, and these are awesome.

I use these on a right-angle cordless drill. I find these 3" discs to be easier to handle than my 4" angle grinder using the 4" flap discs. I use them primarily on aluminum and copper fabrications. They are long lasting and when worn they are great when you need to clean up a surface, a weld or a corner and you want an abrasive wheel that has a reduced bite. I find that these flap wheels are useful until there is nothing left on them.

I use a lot of these for grinding details on small welding projects. Super handy for cleanup and weld prep work in tight areas and on small parts.

The BA Mini Flap Discs work awesome with my Milwaukee M12 right angle die grinder to get into tight spots. Last for a good amount of time for their size. Will be purchasing more in the future.

I bought these with the assumption they would die quickly, and be useful for very precise detail. I was wrong. --- they last a surprisingly long time, and they are useful for precise detail. Bought'm on a curious whim. Now they are a valuable part of my metal sculpting repertoire

Using as grinder for back sanding crown mouldings. Lots of dust, but faster than a couping saw.

Product Specification
3" MINI FLAP DISC ZIRCONIA QUICK CHANGE DISCS
3" Mini Flap Disc Zirconia Quick Change Discs are manufactured using European zirconia cloth. The European material is superior due to its uniform particle size and premium blend of ingredients. These discs exceed other flap discs by packing 25 to 50% more abrasives on each snippet (compared to the competition). In addition, all discs are manufactured on computer-controlled machines and subject to numerous tests which ensure high quality and greater safety.
These mini flap discs are manufactured using premium VSM Zirconia cloth. The VSM material is superior due to its uniform particle size, aggressive cut, and premium blend of ingredients. Benchmark Abrasives min flap discs are great for cleaning weld lines and weld splatter, deburring, deflashing, removing rust, blending, or general stock removal in narrow, small areas. These mini flap discs have adhered to an R-Type backing (equivalent to 3M Roloc fastening system).
These quick-change sanding flap discs are ideal for metal grinding, hardware polishing and automotive, tensile grinding capacity. This quick change flap disc can be used with any air or electric drill, die grinder, and other rotary tools for the utmost sanding control.
T27 (flat face) discs are perfect for grinding down items that are not flat surfaces (like fence posts, gates and risers etc).  For the best solution on flat surfaced check out our T29 (angled face) flap discs.
Zirconia grains have a self-sharpening property and stand up to higher heat and pressure than Aluminum Oxide (A/O), thus making Zirconia the go-to option, providing excellent stock removal that gives you more bang for your buck.

Use in combination with our 3” Quick Change Rubber Mandrel
