Sometimes cheap tips are enough to get the job done, but if you want perfection, don't skimp. Whiteside Beats are among the best and this beat is no exception.
Over the years I have trusted Whiteside cutters for their performance and durability. This drill meets my expectations and produces a smooth, clean cut. (Be sure to make multiple passes, adjusting the depth of cut on each pass until the desired depth is reached.)
I use this bit in my router with a template I made that allows me to make a compound radius fretboard for acoustic guitars. After using this tip and getting any joint radius you want, little to no sanding is required. The bit cuts well and does the job very smoothly.
