YCC Nail Drill Bits - Mandrel 3/32How to Use Mandrel Nail Drill Bits (with Sanding Band Grit Guide): Choose Sanding Band:Select sanding bands with different grit levels depending on the job: Coarse (80 grit): Great for prepping acrylics or hard gels. Medium (100–120 grit): Ideal for shaping enhancements or prepping the nail surface. Fine (150–180 grit): Best for smoothing the nail surface and refining shape. Extra Fine (240+ grit): Used for finishing touches and prepping natural nails gently. Insert the Mandrel Tool:Place the mandrel (metal rod) into your electric nail drill handpiece securely. Attach the Sanding Band:Slide the sanding band over the mandrel or attach the appropriate bit firmly. Ensure it’s snug and not loose. Adjust the Speed Setting:Use low speeds for natural nails and higher speeds for artificial enhancements. Adjust based on the grit used. Apply Light Pressure:Gently guide the bit across the nail surface. Use Short, Even Motions:Avoid staying in one spot too long to prevent heat build-up or damage. Clean and Sanitize:After use, remove the sanding band (discard after one use).
