Salon manicures add up fast. A fill every couple of weeks, plus tip, and suddenly your nails cost more than your phone plan. So you buy an electric nail file, and it arrives with two or three bits that are dull, mismatched, or a bit too aggressive for natural nails.
I've been there. Swapping to a proper set of nail drill bits changed my at-home routine more than any machine upgrade did. Here's what I found in the Depvko set, including what it can't do.
Why Your Nail Drill Is Only As Good As Its Bits
The motor gets the attention, but the bit does the actual work. A dull bit tugs and heats up. The wrong shape leaves ridges or irritates your skin. A good bit glides, and you hear that smooth, quiet hum as dead skin and old product lift away.
That's why a varied set matters. You need one tool for the cuticle area, another for shaping, another for buffing. Buying them one by one gets pricey. A nail drill bit set of 21 pcs solves that in one go.
Meet the Depvko 21-Piece Nail Drill Bit Set

This Depvko kit is an Amazon's Choice pick with a 4.7-star rating across more than 11,000 reviews. At around $9.99, it works out to roughly 48 cents per bit. You can grab the 21-piece set here on Amazon.
Everything You Need in One Dust-Proof Box
The bits live in a compact, see-through case that keeps dust out. You can spot the shape you need at a glance, and it slips easily into a drawer or travel bag. Small thing, but it keeps your station tidy.
Premium Diamond & Ceramic Bits: Built to Last
These are high-precision diamond and ceramic bits, made for strength, sharpness and durability. The ceramic nail file bits are great for smoothing and shaping, and the diamond-style bits handle cleanup around the nail. They're also sold as carbide nail bits alternatives for people who want a long-lasting set.
Universal 3/32" Fit: Works With Most Nail Drills
The shank is the standard 3/32 inch, so these 3/32 nail drill bits fit most electric and rechargeable manicure machines. Quick heads-up from the listing: the electric nail drill itself is not included. This is a bits-only kit.

For about $9.99, the Depvko 21-piece set is an easy way to upgrade your home manicure routine. You get variety, a universal fit and a tidy case. Pair it with a 3/32" drill, take it slow, and you'll feel the difference.
What's in the Box: 21-Piece Breakdown
Bit type | Qty | Best for |
|---|---|---|
Under-Nail Cleaner (UNC) bits | 7 | Cleaning under the free edge and around the cuticle area |
Ball-shaped bits | 2 | Gentle work around the nail sidewalls |
Flame bits | 2 | Detail work and cuticle area cleanup |
Brush bits | 2 | Brushing away dust and debris |
Ceramic nail file bits | 8 | Filing, shaping and refining nail edges |
Total | 21 | Cleaning, filing, shaping, polishing |
If you do your own cuticle drill bits work or remove acrylic, having seven UNC bits is a nice touch. You can swap in a fresh one whenever you need it.

Who Is This For?

Home manicure lovers who want to skip some salon visits.
DIY nail artists who need clean prep before design work. These are solid DIY nail art tools for the budget.
Beginners upgrading from the one or two bits that came with their machine.
Nail techs on a budget who want spare acrylic nail drill bits on hand.
Gift shoppers buying for the friend who has everything nail-related (just make sure she owns a 3/32" drill).
Beginner Tips & Safety
An honest note: always use drill bits with proper technique and at appropriate speeds. This set is not a substitute for professional training.
Start on the lowest speed and practice on a tip or a nail practice hand first.
Keep the bit moving. Never press hard or hold it in one spot.
Use light pressure near the skin and cuticle area.
Stop if the nail feels warm or you feel any discomfort.
Watch a tutorial or take a class before moving on to acrylic removal.
