The Diamond Cool Groove Nail Drill Bits Rounded Top Cylinder (DGC) are precision tools designed for professional e-file manicures. These innovative nail drill bits feature a rounded top cylinder shape, combining the benefits of a ball and a cylinder bit in one. The head size of these bits is 2.7*7 mm, making them suitable for various nail treatments.

One of the standout features of these nail drill bits is the non-standard cross cuts on the surface of the diamond cutters. These cuts, with a depth of 0.1 mm, play a crucial role in enhancing air circulation during the manicure process. By improving heat dissipation, they prevent overheating and discomfort, ensuring a more comfortable experience for the client. The cross cuts also contribute to faster and cleaner manicures.

The Diamond Cool Groove Nail Drill Bits are known for their exceptional sharpness. The cutting edges of these bits are finely crafted, enabling precise and efficient nail work. Whether you need to remove raised cuticles, polish the cuticle zone, shape the free edge of the nail, or clean the nail wall, these bits deliver reliable performance.

Durability is another key feature of these nail drill bits. The bits are coated with durable diamond material and feature a hexagonal shape, which increases their longevity. This means that you can rely on these bits for extended use before needing to replace them, saving you time and money.

These bits are available in two variants:

Fine (red) bits are specifically designed for gently and accurately removing raised cuticles, making them suitable for sensitive skin. They are also recommended for preparing natural nails before applying acrylic nails and for polishing the cuticle zone after cuticle removal.

Medium (blue), on the other hand, are ideal for removing dry, dead cuticles around the nails and cleaning the nail wall. They are also effective for shaping the shape of the free edge of the nail, allowing for a rounded and neat finish.

After completing a procedure with a client, need proper cleaning and sterilization. Here are some guidelines for cleaning and disinfecting nail drill bits:

Remove any debris: Before starting the cleaning process, remove any visible debris or nail dust from the drill bits.

Beautiful
Color: All black
Having never previously owned a self-winding watch, and because the wristband did require some link-removal adjustment, I did hold off on wearing it for a few days until I could schedule an appointment with my jeweler to have the day/date setting and band-adjustment done. But a major part of my reason for doing so was my strong impression upon receipt of the watch that this was a very good choice. It is a very beautiful watch to look at, though compact and not overly bulky like many chronograph-style watches, its' heft conveyed a sense of a very solid, well designed and constructed watch. Since having the setting and adjustments done, I have been extremely pleased with how accurately it keeps time. In short, I LOVE this watch. I will also note this. Though my jeweler retails various high-end, and much more expensive watches, he was clearly impressed with the look and feel of this watch, and even made explicit comment about what a beautiful watch he felt it was. That said, I do have a quibble. The writing of the accompanying instruction booklet was riddled with English grammatical errors which were quite frustrating, and contributed to my reason for opting to have my jeweler complete the settings and adjustment. Also, when I contacted OLEV online to solicit guidance on how to expedite registering the purchase for warranty purposes, I received an email auto response saying that any Amazon purchase would require customer service and other guidance through the seller. Since my assumption upon Amazon purchase was that I WAS purchasing from OLEV as the seller, this remains a source of confusion which I yet need to resolve.

Doesn’t keep accurate time
Color: All black
I bought this for my husband because it said that it self winds but my husband noticed that it didn’t work within the first few days so I thought maybe it was defective so I purchased another one in exchange for the first one but the second one had the same issue. Don’t waste your money on this, it doesn’t work.
