RotoZip XB-DW Drywall X Bit 5/32” Fast Cut.

The price is $22 for a pack of 10 bits. Cheaper than anywhere you will find online. May be able to meet in Salt Lake or deliver if you purchase enough.

Not in original Rotozip packaging, but they are new bits.

I have hundreds of these bits. If you are interested in purchasing in bulk let me know, we may be able to work out a deal.
