Question
The range of the helix angle of the twist drill is
Solution
The range of the helix angle of the twist drill typically falls between 20 to 30 degrees. This angle can vary depending on the type of material being drilled. For example, a larger helix angle is used for softer materials, while a smaller angle is used for harder materials. The helix angle also affects the rate of chip removal, with a larger angle allowing for faster chip removal.
