Bosch GCS18V-230N 18V Brushless 9-Inch Cordless Concrete and Metal Cutoff Saw Bare Tool
The Bosch GCS18V-230N 18V Brushless 9-Inch Cordless Cutoff Saw cuts cured concrete, rebar, steel pipe, masonry pavers, and structural cinder block with a maximum cutting depth of up to 3.3 inches. Powered by an industrial high-torque brushless motor engineered for heavy demolition and utility fabrication, this cordless cutoff tool delivers gas-free indoor cutting without hazardous engine emissions or pull cords. Featuring an integrated wet-cutting water feed with an onboard shut-off valve, an enclosed waterproof battery compartment, a 6-position adjustable wheel guard, and an ergonomic wraparound handle, this 11.8-pound portable saw equips concrete contractors, masons, and commercial metal fabricators with balanced cutting control. **Battery and charger sold separately.
Best Used For:
Concrete Slab & Paver Cutting: Making up to 3.3-inch deep relief cuts and sizing brick pavers using the wet-cut water attachment to suppress airborne silica dust.
Rebar & Structural Steel Sectioning: Slicing heavy-duty steel pipe, structural rebar cages, and metal studs cleanly on jobsites without trailing power cords.
Indoor Demolition & Plumbing Trenching: Sinking floor cuts in basements and occupied commercial facilities where gas-powered saw exhaust is prohibited.
Key Performance & Safety Features
High-Output Brushless Motor: Delivers corded-equivalent cutting power and constant rotational speed under heavy concrete and steel loads.
Integrated Wet-Cut Water Delivery: Directs water spray directly to both sides of the blade with an accessible brass shut-off valve for OSHA Table 1 silica compliance.
6-Position Adjustable Blade Guard: Rotates smoothly around the 9-inch wheel to optimize sightlines, spark deflection, and ergonomics across varying approach angles.
Sealed Waterproof Battery Bay: Enclosed compartment shields 18V lithium-ion battery packs from water slurry, concrete slurry, and jobsite dust intrusion.
Spindle Lock Lever Mechanism: Simplifies wheel swaps by locking the 7/8-inch arbor firmly for fast blade exchanges using the included on-tool wrench.
AMPShare™ System Compatibility: Operates seamlessly across the global multi-brand AMPShare and Bosch Professional 18V battery platforms.
