Which tool is used to produce a precise 90-degree angle, often used for wood joinery?

• A. Circular saw
• B. Jigsaw
• C. Planer
• D. Miter saw (or miter box with a backsaw)

Answer: (D)

A tool that provides a stable reference and a controlled cut is used to produce a precise 90-degree angle for wood joinery. The miter saw does this best: its blade pivots on a swing-arm with a solid fence and built-in angle gauge, allowing you to lock in a perfect 90-degree crosscut and repeat it accurately for frames, boxes, and other joints. If you prefer a manual setup, a miter box with a backsaw guides the blade in a 90-degree slot to achieve the same right-angle cut. A circular saw can cut straight, but keeping a true 90-degree angle consistently is harder; a jigsaw is for curved or irregular cuts; a planer is for thickness and surface finishing, not angle cuts. So, the precise 90-degree angle tool is the miter saw (or miter box with a backsaw).
