National Occupational Competency Testing Institute (NOCTI) Carpentry Practice Exam

To ensure accurate angle transfers, carpenters use which of the following tools?

1. Framing square

2. Speed square

3. Builder's level

4. T-bevel

The correct answer is: T-bevel

T-bevels are designed specifically for transferring angles with precision. This tool features an adjustable blade that can be set at any angle, allowing carpenters to accurately replicate the angle onto another surface or material. This capability is particularly useful when working with complex cuts or irregular angles, ensuring that the angle is maintained throughout the project. While other tools like framing squares and speed squares are invaluable in carpentry for straight cuts and right angles, they don’t offer the same versatility for transferring a variety of angles. A builder's level is primarily used to ensure that surfaces are level and plumb rather than for transferring angles. Thus, the choice of a T-bevel reflects an understanding of the specific task of transferring angles accurately in carpentry work.
