Bosch GCU18V-30N 18V Brushless Cordless Cut-Out Rotary Tool – 1-Speed, Depth Adjustable, Dust Control (Bare Tool)

The Bosch GCU18V-30N 18V Brushless Cut-Out Rotary Tool delivers corded-level power, all-day runtime, and precision performance—perfect for drywall installers, plasterers, and interior finishing professionals. When paired with a Bosch CORE18V 4.0 Ah Compact battery (sold separately), it can cut up to 330 linear feet of 1/2" drywall in a single charge using a 1/8" bit.

Powered by a high-speed 30,000 RPM brushless motor, this tool ensures fast, clean cuts in drywall and plaster, while the IP 5X-rated dust-resistant switch extends lifespan in tough, dusty jobsite conditions. A convenience brake stops bit rotation instantly for safety, and soft-start technology minimizes start-up torque for smoother control.

The adjustable footplate allows quick depth-of-cut changes, and the dust hood connects to a vacuum for efficient dust collection. Its compact, ergonomic grip ensures maximum comfort and control, while the built-in LED light illuminates the cutting path in dim spaces. Comes standard with three collets (1/8", 5/32", and 1/4") for compatibility with market-standard bits.
