Awesome accessorie!

Who knew grinding could be so much easier! I've been doing stained glass for 30+ years and wish I would have known about this sooner. Toss the sponges and get this tool, you won't be sorry.

Love, love, love it.

It didn’t think it would work, but is does. Will never go back to a sponge.

Love the invisible sponge bitsert

The 1" bitsert is great. No more gunky sponge to deal with. Much less spray as well.
