Bosch GCU18V-30N-RT 18V Brushless Drywall Cut-Out Tool Reconditioned Bare Tool

The Bosch GCU18V-30N-RT is an 18V brushless cordless drywall cut-out tool engineered for rapid outlet box cutouts, HVAC vent trimming, and ceiling tile fitting. Operating at a no-load speed of 30,000 RPM, this rotary tool utilizes a multi-collet system accepting 1/8-inch, 1/4-inch, and 5/32-inch bits to cut cleanly through drywall, plywood, and acoustical tile. Featuring an IP 5X-rated dust-resistant power switch, an electronic motor brake, an adjustable footplate for depth control, an LED worklight, and an included vacuum dust extraction hood, this compact 2.1 lb tool maintains clean site conditions during interior finishing passes.

Note: This is a manufacturer-reconditioned tool, certified to look and perform like new.

**Battery and charger sold separately.

Best Used For:

  • Drywall Electrical Box Cutouts: Routing quick, precise perimeter openings around single and multi-gang outlet boxes in 1/2-inch and 5/8-inch drywall.
  • Acoustical Ceiling Tile Fitting: Trimming interior drop-ceiling tiles, ductwork penetrations, and light fixture recesses without material crumble.
  • Thin Wood & Plywood Panel Routing: Cutting intricate interior profiles and vent openings through thin plywood underlayment and wood paneling.

Key Performance & Safety Features

  • 30,000 RPM Brushless Motor: High-efficiency DC motor delivers corded-equivalent cutting speed while optimizing battery runtime.
  • IP 5X-Rated Dust-Resistant Switch: Sealed internal switch housing prevents fine gypsum and wood dust contamination to extend switch life.
  • Electronic Convenience Brake: Automatically stops bit rotation in seconds upon switch deactivation for rapid jobsite handling.
  • Versatile Multi-Collet System: Supplied with 1/8-inch, 1/4-inch, and 5/32-inch collets to support diverse guidepoint and spiral cutout bits.
  • Adjustable Depth Footplate: Quick-locking footplate sets precise plunge depths to protect hidden wiring, plumbing, and insulation behind wallboards.
