Review on RotoZip GP8 8 Inch Drywall Cutting by Mark Fleming

The whole house audio plan for a house under construction includes about 14 speakers that I will mount to the rafters on ¼" thick plywood. Used a 1/8" RotoZip GP8 drywall cutter with a 1/8" pilot tip to see if it would cut drywall using a plywood speaker mount as a guide. The painting was my first test hole. Works fast and does the job I need.
