do you use a simple 1/4 inch drill bit (assuming they are being made to fit on a standard A mandrel)? A 6.3 mm bit would be a better fit, but I'm not enthused about spending $45 for one.
I've made several different sets for myself and friends and have drilled all at 1/4 with no issues.do you use a simple 1/4 inch drill bit (assuming they are being made to fit on a standard A mandrel)? A 6.3 mm bit would be a better fit, but I'm not enthused about spending $45 for one.
