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.

Actually feels cool at night
Color: Light Gray, Size: Standard
I’ve been using these for several days now and I did notice a difference. I tend to get hot while sleeping, so I was curious if they would actually help, and they do feel cool when you lay on them. I also like that they’re soft and comfortable, not that weird texture some “cooling” products have. So far, I’ve been really happy with them.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉

Stretchy Material and Cooling Fabric
Color: Light Gray, Size: Standard, Color: Light Gray, Size: Standard
Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case. Durability: zipper works great and material is easy to clean. Color: I have the gray and my daughter has the pink. Both colors as advertised. Value: Good value and I got what I expected.
