How These Bits Saved a $28k Fender Guitar from Becoming Firewood
When the master luthier saw tear-out in the quilted maple guitar top, his vein pulsed like a live wire. Then the Whiteside RU2100 series stepped onto the bench. These carbide-tipped surgeons carved binding channels with zero blowout, saving the 200-hour build with cuts cleaner than a diamond splitter. For custom cabinetmakers and instrument artisans, this isn’t a bit set—it’s liquid-smooth insurance.
