Bosch PLH181B 18V 3-1/4" Cordless Hand Planer - Bare Tool
The Bosch PLH181B 18V cordless 3-1/4-inch planer levels uneven timber framing, planes tight-fitting entry doors, chamfers sharp board edges, and shapes architectural casing without trailing extension cords. Powered by a high-output four-pole motor spinning at 14,000 no-load RPM, this 4.5-lb woodworking tool utilizes a counterbalanced single-blade drum system fitted with a Woodrazor micrograin carbide blade for rapid stock removal and glass-smooth surface finishes. Outfitted with precision-machined aluminum front and rear shoes, a ratcheting depth knob adjustable from 0 to 1/16 inch (1.5 mm), dual-directional chip ejection ports, and an ambidextrous edge guide fence, it equips finish carpenters, cabinetmakers, and door installers with portable surface flattening accuracy.
**Battery and charger sold separately.
Best Used For:
- Entry and Interior Door Trimming: Sizing and beveling bottom door rails and hinge stiles directly on hinges or sawhorses without tear-out.
- Architectural Trim and Cabinet Scribing: Planing hardwood filler strips, face frames, and baseboards to fit flush against out-of-plumb drywall.
- Framing Stud and Joist Surface Leveling: Shaving high spots on rough-sawn dimensional lumber and engineered floor joists prior to subfloor installation.
Key Performance & Safety Features
- Woodrazor™ Micrograin Carbide Blade: Fracture-resistant reversible carbide cutter resists edge chipping from embedded staples and nails while delivering mirror-smooth finishes.
- High-Speed 4-Pole Motor: Generates 14,000 RPM for fast material removal across dense hardwoods, softwoods, and composite panels.
- Ratcheting Depth Adjustment Knob: Calibrated dial sets cut depth accurately from 0 to 1/16 inch (1.5 mm) in a single turn without needing to re-zero.
- Dual-Direction Chip Ejection: Integrated selector switch directs wood shavings and chips out of the left or right side exhaust port to maintain a clean work line.
- Precision-Machined Aluminum Shoes: Front and rear shoe plates are post-assembly machined to ensure planar alignment and eliminate workpiece gouging.
- Electronic Motor & Cell Protection: EMP and ECP circuitry prevent thermal motor overloads and safeguard battery packs against deep discharge.

Pro-Tip: When chamfering sharp 90-degree lumber corners, align the V-groove in the front aluminum shoe squarely over the board edge; this keeps the tool tracking at a perfect 45-degree angle across the full length of the workpiece.
