BIAB Debulking Bits

Comparison Chart: BIAB / Builder-in-a-Bottle Debulking Bits

 

Grit Aggressiveness Best For Typical Use Stage Client/Product Type
Fine Gentle Light thinning, refining BIAB layers Last step before hand filing; thinning out minimal product Thin BIAB layers, sensitive clients, soft builders
Medium Moderate Everyday BIAB debulking Main debulk step; removing down to a thin base Standard BIAB, moderate structure, average thickness
Coarse Strong Fast removal of thicker BIAB / encapsulated layers Initial bulk removal; heavy reduction work Structured BIAB, encapsulated builds, thicker overlays

Quick Notes 

  • Fine → best for delicate work and clients with thin or sensitive nails

  • Medium → ideal everyday grit for BIAB maintenance

  • Coarse → powerful, fast debulking for heavily built BIAB or encapsulated designs
