One shape, two services — with more removal power. The Bone's 4mm long tapered barrel works as a Step 1 cuticle bit — removing pterygium and lifting the nail fold — and doubles as an E-Pedi bit for reducing calluses, fissures, and cracks. Medium grit gives it more bite than the Fine version, making it the better choice for clients with heavier build-up. Cooling grooves keep the client experience comfortable throughout.
Suitable for both left-handed and right-handed use.
WHAT IT DOES
- Removes pterygium and lifts the nail fold at Step 1 of manicure prep
- Reduces calluses, fissures, and cracks during E-Pedi services
- Longer barrel covers more surface area per pass than standard barrel bits
- More removal power than the Fine version — better for heavier build-up
- Cooling grooves reduce heat build-up for a comfortable client experience
- Real lab-grown diamond delivers up to 1.5x the lifespan of standard diamond-coated bits

IMPORTANT: HOW TO USE
Manicure prep (Step 1):
- Work at 9,000–11,000 RPM with very light pressure
- Guide around the cuticle area to remove pterygium and lift the nail fold
- Do not use on the nail plate
E-Pedi (callus, fissure & crack reduction):
- Work at 15,000 RPM with light, controlled pressure
- Focus on specific problem areas; keep the bit moving
-
Always leave approximately 10% of hardened skin — never remove all callus in one session

CLEANING & CARE
Step 1 — Clean: Use warm soapy water, the Willow Spit-Spot-Bit-Pot, and the Willow Brass Brush to remove dust and product debris. Alternatively, use your Ultrasonic Cleaner with detergent on the relevant cycle.
Step 2 — Disinfect: Use your preferred method. The Willow Spray & Go 2-in-1 is recommended — lay bits on a towel, spray evenly, roll over and spray again. If soaking, steep for the recommended time only — over-steeping dulls the bit.
Step 3 — Dry & Store: Wait 2 minutes then dry thoroughly by hand. Do not air dry. Store in a bit case or bit book.
When to replace: If the bit originally took 1–2 passes to penetrate product and now takes 3+, it's time for a new bit.
