What angle range is associated with masonry drill bits?

15 to 25 degrees
30 to 45 degrees
45 to 60 degrees
60 to 75 degrees

The correct answer is: 30 to 45 degrees

Masonry drill bits are specifically designed for drilling into hard materials like brick, concrete, and stone. The angle range associated with these types of drill bits typically falls between 30 to 45 degrees. This angle is crucial for ensuring that the drill bit effectively penetrates tough surfaces while also minimizing wear and tear on the bit itself. The geometry of the drill bit, including its angle, influences the cutting action and the ability to remove material effectively. A sharper angle, as found in masonry bits, allows for better control and efficiency when drilling into hard substrates, enabling successful anchoring or installation in construction tasks.
