Applications for this tool include SMT parts, metal parts, plastic parts, or any item having a smooth, nonporous surface that the rubber vacuum tweezer's tip can seal against. This tool can be used with any of our rubber vacuum cups ranging in size from 3/8" (9.53mm) to 3/4" (19.05mm) in diameter. Use the larger cups to pick up larger and heavier parts. For better precision in part placement, see our PEN-VAC or PEN-VAC PRO-Series self-contained vacuum pens.
