Choice S1-1 set-5PCS 5pcs Stainless Steel Nail Drill Bit for Gel Removal Cuticle Burr Bits Milling Cutter F

1. TWO 5-PIECE PURCHASE OPTIONS

Each package contains 5 stainless steel nail drill bits. Choose a mixed-color 5-piece assortment for multiple grit levels in one organized set, or select a single-color 5-piece option when you need five bits of the same grit. This flexible configuration works well for building a complete e-file collection or restocking the grit used most frequently during daily nail services.

2. STAINLESS STEEL WORKING HEAD AND SHANK

Both the working end and metal shank are made from stainless steel, providing a solid all-metal construction for regular electric nail file work. The rigid working head supports controlled contact during product reduction, shaping and refinement, while the straight stainless steel shank provides stable installation in a compatible nail drill handpiece.

3. COLOR-CODED GRIT LEVELS

Available grit grades make it easy to match the bit to different stages of an e-file service. Purple identifies Double Fine, Yellow identifies Extra Fine, Red identifies Fine, Blue identifies Medium, Green identifies Coarse and Black identifies Extra Coarse. The colored identification band provides quick visual recognition when switching between different filing levels.

4. STANDARD 3/32-INCH E-FILE SHANK

Each bit features a 2.35mm / 3/32-inch straight shank, the commonly used size for professional manicure e-files. The standardized diameter allows the bits to be installed in compatible electric nail drill machines that accept 3/32-inch accessories, making them suitable for salon nail stations, nail technician kits and personal manicure setups.

5. VERSATILE E-FILE WORKFLOW

Designed for use with an electric nail drill, these stainless steel bits can be incorporated into multiple stages of manicure and enhancement maintenance. Depending on the selected grit and working-head profile, they can be used for artificial nail product reduction, gel or builder gel refinement, acrylic reshaping, surface contouring, edge correction, sidewall detailing and preparation work around appropriate nail areas.

The different grit options allow technicians to move from stronger material reduction to controlled shaping and lighter finishing without relying on one filing level for every task.

6. MATCHING COLOR STORAGE BASE WITH CLEAR COVER

Every bit is supplied with a plastic storage base that matches the color of its identification ring, allowing the grit level to be recognized quickly even while the bit is stored. A transparent protective cover keeps each bit separated and organized between uses. The coordinated color system is especially convenient for professional workstations where several grit levels are used throughout the day.

Sidewall and nail groove cleaning: 10,000–16,000 RPM

General surface refinement: 12,000–18,000 RPM

Always begin at a lower speed and increase gradually when necessary.
