What the AI looks for in Electric Nail Drill Bits

Shank size: 3/32 inch (2.35 mm) shank for nail e-files; 1/8 inch (3.175 mm) shank fits Dremel-style rotary tools, not nail handpieces The wrong shank will not lock in the chuck, or it wobbles and can damage the handpiece and the nail.
Material for the job: Carbide for removing acrylic and hard gel; diamond for cuticle work and natural-nail prep; ceramic for heat-sensitive product removal; sanding bands on a mandrel for shaping Carbide on a natural nail thins and burns it, while diamond on thick acrylic clogs and overheats.
Grit: Use fine or extra-fine grit near the cuticle and on natural nails, and coarse grit only for bulk product removal Coarse grit near skin causes cuts and heat burns. Color codes are not standardized across brands, so check each brand's own chart.
Concentricity: The bit should spin without visible wobble at working speed An off-center bit chatters, digs grooves and wears the handpiece bearings.
Hand orientation: Cross-cut carbide bits come in right-hand and left-hand cuts; match the cut to your drill's spin direction Running a cut against its direction drags and grabs instead of cutting cleanly.

Kiara Sky: Nail-salon brand with a broad range of carbide and diamond e-file bits.
Medicool: Long-standing e-file maker that sells bits sized for its own and other 3/32 inch handpieces.
Startool: Specialist bit maker known among nail technicians for carbide bits.

Only if the Dremel has a 3/32 inch collet. Most Dremels ship with a 1/8 inch collet, and Dremels run rougher than a nail e-file.
