Why Medium & Coarse Diamond Bits Are the Game-Changers You’ve Been Missing in E-File Dry Manicure

What No One Tells You About Diamond Bits (But Should!)

For many years, nail educators—especially in Russian and European systems—have advised using only red 🔴 (fine) grit diamond bits when performing E-File dry manicures. While that advice may seem safe, here’s what most don’t realize:

🔍 The Problem with Fine Bits:
Fine bits wear down quickly. In fact, they may only last for about 9 uses before their efficiency drops. For busy techs, that translates to more time spent on each client and higher replacement costs.

💡 The Better Alternative:
Through years of testing and hands-on experience, we’ve discovered that medium and even coarse diamond bits, when used correctly, offer faster, more efficient, and longer-lasting results.

👉 With the proper technique, grip control, and understanding of your e-file’s RPM settings, these bits can safely exfoliate dead skin and lift cuticles—without causing trauma to the nail plate or living tissue.

🌀 What Makes Our Bits Different:
SHi® is proud to be the first U.S. brand to introduce TIN-coated diamond bits with cooling groove technology:

• ✔️ 30% longer lifespan
