    3" Quick Change Disc A/O - 25 Pack

    Posted by bwob2000 on Aug 23rd 2019

    Bought the 25 pack Aluminum Oxide discs as replacements for a disc pad holder purchased at a big box store (who did not sell replacement discs - bad on them!). Been using the discs to prepare a cast iron surface for finishing. So far discs have been doing a good job and the price seems reasonable. I might look for a the ceramic ones next time as the cast iron can be pretty hard. Delivery was quick. Would recommend to others.

    Using the 3” aluminum oxide 40 grit for trim hole grinding after they’ve been mig welded shut on a 72’ Ford Ranger XLT. Used 3 so far. They last a long time. Good product.
