Dark TVS Bits: How to Choose Without Getting It Wrong

Carbide bits are the most durable tool in nail work — and for good reason. TVS stands for hard alloys: a material based on tungsten carbide. It's significantly harder than standard steel, doesn't dull after a few clients, and — most importantly — withstands autoclaving without deformation or corrosion. Dark carbide bits are one of the most worthwhile investments a technician can make: a single quality Dark TVS cutter lasts many times longer than cheaper alternatives.

And if you do your own nails at home, don't worry — TVS nail drill bits Dark are perfectly manageable once you understand which attachment to use and when. More on that below.

Colour Coding: What Blue, Green, and Red Mean

The colour ring on the shank is your guide to grit level.

• A blue TVS bit Dark has medium hardness. It works gently and is suited for natural nails, lateral wall treatment, and cuticle work. If you're just getting started with machine manicure, blue is where to begin.
• A green TVS bit Dark is coarser. It's designed for removing dense coatings: gel polish, acrylic, builder gel. This is a coarse removal bit Dark that takes off material quickly without letting it "melt" from heat — which is why it's often simply called a coarse Dark carbide bit or gel removal bit Dark.
• A red TVS bit Dark has a fine grain and a delicate action. It's suited for finishing work, surface polishing, and working with thin or sensitive nail plates.

Blue Series

• Dark TVS bit No.02 blue is arguably the most versatile attachment in the line. Medium hardness, classic cylindrical shape. Suitable for treating the perionychium, removing pterygium, and working with the lateral walls. If you need one blue TVS bit Dark for everything — this is it.
• Dark TVS bit No.202 blue is similar to the one above but has a different cutting geometry. It offers a slightly different working angle, which is convenient with different nail shapes. Ideally, both belong in your working kit.

Green Series — for Coating Removal and Correction

• Dark TVS bit No.03 green is the gold standard for gel polish and gel removal. The serrated surface actively grips the material and removes it evenly. A Dark TVS gel removal bit of this type is in most professional kits — and for good reason.
• Dark TVS bit No.05 green (5 mm diameter) — a more compact version for targeted work in zones where a larger attachment simply won't fit: nail corners, the area around the lunula. The Dark TVS 5mm bit is especially useful when working with short nails.
• Dark TVS bit No.06 green is built for more aggressive, fast removal. When a client comes in with a rock-solid set of extensions and time is tight, this attachment gets the job done fastest.
• Dark TVS bit No.203 green performs well in pedicure: its larger size allows effective work on thick layers of material on the toes.
• Dark TVS bit No.205 green — another attachment from the green series, optimised for foot work. Suitable for treating lateral surfaces and areas with thickened skin. Often referred to as a pedicure bit Dark.
• Dark TVS bit No.206 green for nail correction: it levels the surface after regrowth, removes unevenness, and prepares the nail for a new coating.
• Dark TVS bit No.208 green or the "corn" bit. Here it is, the star of the line. The corn bit Dark, as our clients often call it, is an attachment with a distinctive relief pattern that efficiently removes large volumes of material in a short time. Indispensable when removing acrylic, polygel, and dense builder gel. If you're looking for the best Dark TVS bit for acrylic — the corn bit is the number one choice.
• Dark TVS Left-Handed Bit No.209 Green. This detail is often overlooked, but it matters. The direction of the spiral on a bit determines how the swarf is expelled during work. Standard attachments have a spiral designed for right-hand movement — if the technician is left-handed, the cut is less clean and material builds up in the grooves instead of being cleared away.

Left-handed Dark bits solve this at the geometry level. Dark TVS left-handed bit No.209 has a reverse spiral — designed specifically for the left hand. Technically it's the same carbide quality and the same tooth geometry as the rest of the line, but adapted for left-handed technicians.

Red Series

• Dark TVS bit No.201 red has a fine grain for delicate work. Finishing treatment, nail surface polishing, removing minor unevenness after the main removal. Ideal for clients with thin or damaged nail plates.
• Dark TVS bit No.202 blue and No.201 red are often used as a pair: the coarser one removes the main layer, the finer one brings the surface to a perfect finish.

DARK Safe Nail Bit

A rounded shape with no sharp edges minimises the risk of injury when working near the cuticle. This is the first attachment worth buying if you do your nails at home or are just starting out in nail care.

Bit Care: Making Them Last

DARK carbide bits are sterilisation-resistant and withstand autoclaving — but only when used correctly. A few simple rules worth knowing:

1. After each client, clean the attachment of material residue with a dedicated brush or ultrasonic cleaner
2. Don't run the bit at maximum speed with heavy pressure — this accelerates wear
3. Store separately so the teeth don't contact each other

With proper care, a durable Dark carbide bit built for professionals will serve you for a year or more.
