Nail drill bits are graded by grit, from XF (extra fine) to 4XC (ultra coarse). Coarse carbide bits remove acrylic and builder gel, medium and fine bits remove gel colour, and diamond bits clean the cuticle. Every bit here has a 3/32" (2.35 mm) shank for standard nail drills (e-files).
Not sure which one you need? The nail drill bit grit chart lists each grit, its collar colour and the job it is for. You will also find sanding bands and nail e-files at M1 in Markham, Ontario.
