Intro to Millwright Practice Exam

Which statement is true regarding the use of power saws?

1. Their blades are sized by length and number of teeth

2. They are used exclusively for metal cutting

3. They have no specific sizing standard

4. They can only be used with single tooth blades

The correct answer is: Their blades are sized by length and number of teeth

The statement that blades of power saws are sized by length and number of teeth is accurate. The length of the blade is critical for ensuring it fits securely and operates properly within the saw, while the number of teeth affects the finish of the cut and the material being cut. A higher tooth count is typically suited for smoother cuts in materials such as wood or plastic, while a lower tooth count is better for faster cuts in materials like metal. In contrast, the other statements do not accurately reflect the characteristics and applications of power saws. Power saws are not limited to metal cutting; they are widely used for cutting various materials including wood, plastic, and composite materials. Additionally, there are specific sizing standards for power saw blades, relating to their diameter, thickness, and tooth count among others, ensuring compatibility with different saw models. Furthermore, power saws can utilize various types of blades, not just single tooth blades, allowing for versatility in tasks and materials.
