Paint never hides a mold line — it highlights one. This set of three diamond files in different profiles handles the prep work that makes finishes look factory: seam lines on figure sets and vehicles, sprue gate stubs on structure kits, and mating surfaces that need to sit flat before gluing. Diamond grit cuts plastic, resin, and metal without clogging the way conventional files do.
Complete the cleanup chain with the Precision Side Cutter and Hobby Knife.
Will these scratch clear parts?
They're for prep surfaces, not glazing — for window material use progressively finer sanding films instead.
Diamond vs. regular needle files?
Diamond grit doesn't clog with styrene shavings and keeps cutting resin and metal long after steel files dull.
How do I clean them?
A brass-bristle brush or a quick scrub with an old toothbrush and soapy water restores the bite.
