One shape, two services. 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. Its length covers more area per pass than shorter barrel bits, making it one of the most versatile bits in the range. Fine grit and cooling grooves deliver a featherlight touch in both applications.
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
- 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
BONE FINE VS BONE MEDIUM — WHICH TO CHOOSE?
| Bone Fine |
Gentler touch — sensitive skin, lighter cuticle work, finer callus refinement |
| Bone Medium |
More removal power — standard prep, heavier pterygium, stronger callus reduction |

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.
