Before you install press-fit tuner bushings, be sure they'll fit correctly, so your tuners will work efficiently. Too tight, and they can chip the peghead finish or crack the wood. Too loose, and they can rattle or fall out. Our custom reamers cut a clean, accurate counterbore for a professional job.
If you have a repair shop, you'll want the complete set on hand. Be ready for any tuning machine installation!
Designed for slow-speed use in your drill press, each steel reamer is 2-3/4" (69.85mm) overall length, with a 1/4"-diameter (6.35mm) pilot and two 1" (25.40mm) cutting flutes. The set of five includes sizes for popular guitar and mandolin press-fit tuner bushings.
