Greetings: I'm trying to spline a new tuner buttons for my Keith D-tuners. By measurement, a 5.5 metric triple square 12 point spline bit will work; however, I can only locate 5 and 6 mm. So does anyone have an alternative spline substitute? Does anyone have a non working Keith tuner that is not being used? Thanks for any assistance.
Ultimately, might be easier just to get a replacement from Beacon unless you're making up something special.
