Gemm Piano Power Tuning Pin Socket, 3-1/2" long

I can't imagine doing the same job using a hand tool tuner! As long as your drill has sufficient torque, this tuning pin socket is essential if you want to remove piano pins. I disassembled an upright piano and I'm sure this tool allowed me to save several extra hours of laborious twisting using a hand tuner. It sure helped me prevent wear-and-tear and pain in my wrist, arm & shoulder. Considering the pain I avoided this thing is actually pretty inexpensive.

Product was easy to use and did the job nicely
