Professional 18V 12 Inch Cordless Slide Compound Dual-Bevel Miter Saw with Shadow LED

The Bosch GCM18V-12SDN is an industrial-grade 18V cordless 12-inch dual-bevel slide compound miter saw powered by a high-torque BITURBO brushless motor platform. Delivering a high-capacity 3-1/2 inch depth profile and a massive 14-inch horizontal crosscut threshold, this precise structural cutting machinery operates on the high-output PROFACTOR battery system to supply corded-class utility in a 52-2/5 pound jobsite frame. Outfitted with precisely centered sliding tracking rails to minimize mechanical runout, this bare tool utilizes tall 5-1/2 inch support fences, a safety electric motor brake, and an integrated tool-free workspace clamp to execute highly accurate framing, beveling, and trimming passes. **Battery and charger sold separately.

Best Used For:

  • Large Nested Crown Molding: Sectioning heavy 7-1/2 inch nested crown molding profiles and deep architectural cornices cleanly without deflection.
  • Wide Structural Crosscutting: Slicing down dimensional 2x14 framing timber plates and dense engineered joist profiles in a single smooth stroke.
  • Commercial Baseboard Installation: Square-cutting tall 6-3/4 inch baseboards oriented vertically flush against the dual fence guides.

Key Performance & Safety Features

  • BITURBO Brushless Transmission: High-efficiency internal drivetrain uses rare-earth neodymium magnets to convert battery energy into corded-equivalent power.
  • Shadow LED Cut Line Indicator: Projects the physical thickness shadow of the miter blade directly onto the target wood grain for accurate tool-free alignment.
  • Dual-Bevel 47-Degree Range: Permits rapid structural bevel adjustments to both the left and right without flipping the material over on the table.
  • Tall 5-1/2 Inch Sliding Fences: Provides rigid perpendicular surface support for processing high-aspect baseboard stock and trim segments.
  • Integrated Electric Safety Brake: Shuts down blade rotational momentum within brief seconds of trigger release to preserve operator hand safety.

What's Included

  • (1) GCM18V-12SD PROFACTOR 18V 12" Dual-Bevel Slide Miter Saw Base
  • (1) 12-Inch Professional Carbide-Tipped Wood Cutting Miter Blade
  • (1) Tool-Free Workpiece Clamping Sub-Assembly
  • (1) Debris Collection Fabric Dust Bag

Pro-Tip: When executing wide sliding passes through thick composite plank fields, always initialize your shadow LED orientation guide before tracking across the material surface. Pull the blade housing completely forward, sink the motor bevel through the face fibers, and push the carriage toward the guide fences to attain zero-splinter edge lines on structural framing.
