Stanley 12-904 Bailey No. 4 Smooth Bench Plane

Product Description

The STANLEY 12-904 is a Bailey No. 4 smooth bench plane designed for hand-planing wood surfaces to a flat, smooth finish. The No. 4 is the standard general-purpose bench plane used across rough dimensioning, surface leveling, and final smoothing tasks on solid wood and engineered lumber. At 4.23 pounds, it carries enough mass for controlled cutting passes without excessive user fatigue. The Bailey-pattern design uses a time-proven frog, cap iron, and blade assembly that allows straightforward blade adjustment and removal for resharpening in the field or shop.

The STANLEY 12-904 is suited for residential and light commercial finish carpentry, cabinet work, door fitting, and general woodworking. It is a hand-tool staple for carpenters, finish carpenters, and millwork tradespeople who need reliable surface preparation before fastening or finishing. It ships as a single unit and is ready for use after initial blade honing, which is standard practice for bench planes of this type.

Key Features

• Bailey-pattern frog and blade assembly for repeatable depth and lateral blade adjustment
• No. 4 body size — the industry-standard smooth plane for general-purpose wood surfacing
• 4.23-pound weight provides cutting stability without excessive fatigue on extended passes
• Sold individually as a complete, ready-to-hone unit

Compatibility

Designed as an OEM-style replacement or direct-use bench plane compatible with standard Bailey No. 4 replacement irons and cap irons available through typical hand-tool suppliers.

Installation Notes

Installation of a bench plane involves securing the blade assembly within the frog and setting blade depth via the adjustment knob before use — no power tools or electrical shutoff is required. Ensure the blade is properly seated against the frog before tightening the cap iron to prevent chatter during cuts. Blade sharpening before first use is strongly recommended, as bench planes are typically shipped with a factory edge that requires honing to a working sharpness. Follow applicable workshop safety practices when handling and sharpening cutting irons.
