The Truth About Cheap Bits vs. Katie Barnes Quality

When it comes to e-filing, your diamond cuticle bit is the one tool that’s constantly in contact with the natural nail and skin - so its quality matters more than anything. If you’ve ever wondered why some e-file bits are £2 and others are £20+, it’s not just branding - it’s science, safety, and craftsmanship.

In this blog, we’re breaking down:

• What makes cheap e-file bits so risky
• How Katie Barnes diamond bits are made
• Why you really do get what you pay for

The Hidden Dangers of Cheap E-File Bits

Most budget-friendly e-file bits on online marketplaces are manufactured in bulk using low-cost, inconsistent materials. Diamond bits especially are often made with:

• Crushed glass or industrial grit instead of real diamond
• Glue or resin-bonded coatings that wear off quickly
• Rough, uneven coating application
• Unbalanced or unshaped shafts that cause vibration
• Sharp edges that damage skin and cause trauma

Cheap diamond bits don’t just perform poorly - they’re dangerous. They can:

• Create heat and friction

• Tear or gouge the natural nail

• Cause micro-cuts to the eponychium

• Lose sharpness after just a few uses

• Contribute to allergies due to heat and trauma

They might look similar on the surface, but once you’re behind the microscope - the difference is undeniable.

So How Are Katie Barnes Diamond Bits Made?

At Katie Barnes Tool Range, every diamond bit goes through a precision manufacturing process that prioritises safety, performance, and hygiene.

Here’s how your KB diamond bit is made:

• Medical-Grade Diamond Particles
• Only real industrial diamond is used - not crushed glass. This ensures consistent grit and sharpness, with better longevity and control.
• Electroplating Process

Unlike resin-bonded bits, KB bits are made using electroplating, where diamond particles are permanently embedded onto the bit using an electrical charge. This creates:

• Even distribution of grit

• Long-lasting sharpness

• Smoother performance

• No shedding of particles

Hand-Checked Balance & Shape

Each KB bit is hand-checked for balance and uniformity, so your e-file runs smoothly - no wobble, no vibration, no wrist strain.

Autoclave-Safe

Bits are coated to withstand high temperatures and sterilisation, making them fully reusable and safe for salon hygiene protocols.

The False Economy of Cheap Bits

You may think you’re saving money by buying cheap - but it often costs you more:

Why the Right Bit Matters

Whether you’re lifting the cuticle or refining around the sidewalls, your diamond prep bits are in direct contact with skin. That means:

• A poorly made bit = damage, heat, sensitivity, and even allergies

• A professionally crafted bit = comfort, safety, and better retention

Your clients feel the difference. Your results show the difference. And your reputation depends on it.
