General Tools Protractor & Angle Finder #39 – Stainless Steel, Outside, Inside, Sloped Angles, 0° to 180°

Precision for every angle

The General Tools Protractor and Angle Finder #39 is a stainless steel, multi-angle tool designed to measure inside, outside, and slope angles with reliability on wood, metal, and composite surfaces. Its sturdy construction and thoughtful design help you approach layouts with clarity, whether you are marking lines, transferring cuts, or verifying angles on the fly.

With a four-piece sturdy design and a locking nut, this tool lets you transfer angles to your stock with repeatable accuracy. The finely engraved black graduations run from 0° to 180° in opposite directions, supporting both left- and right-handed workflows without flipping tools. Built to endure busy workdays, the stainless steel body resists corrosion and remains readable even under finish coats and grime from real-world projects.

Key features at a glance

• Inside, Outside and Sloped Angles: versatile measurements for complex layouts
• Four-Piece Design with Locking Nut: stable shape transfer and repeatable marks
• Angle Transfer: copy odd or custom angles to a miter saw or marking guide
• Fine Black Graduations: precise 0°–180° readings in dual directions
• Stainless Steel Build: durable for job sites, shops, and daily use

This Protractor is especially helpful when standard protractors or bevels don’t fit your project. It shines in setups for cabinetry, trim work, custom joinery, and intricate frame angles where layout accuracy makes a noticeable difference.

Real-world use ideas

• Set the tool on a workpiece to gauge interior or exterior angles before cutting
• Transfer a complex angle to a miter saw with the locking mechanism engaged
• Check slope or rake on stairs, decks, or crown molding layouts

Note: While this tool can improve layout precision, results depend on proper setup and correct use. Consider it a reliable companion for layout and transfer tasks rather than a guarantee of outcomes.
