Explanation:
Flutes are the helical or straight grooves that run along the length of a drill bit. They serve several important functions in the drilling process. Let's analyze each statement to determine their accuracy.
1. To curl the chip lightly for easier removal:
This statement is correct. The flutes on a drill bit are designed to create a helical or spiral shape as the drill bit rotates. This helical shape helps to curl the chips or debris generated during drilling, making them easier to remove from the hole. If the chips were not curled, they would tend to pack tightly in the flutes, causing the drill bit to jam or overheat.
2. To allow the coolant and lubricant to get down to the cutting edge:
This statement is also correct. During drilling, it is important to keep the cutting edge of the drill bit cool to prevent overheating and premature wear. Coolant or lubricant is typically used to reduce friction and dissipate heat. The flutes provide channels through which the coolant or lubricant can flow down to the cutting edge, ensuring effective cooling and lubrication.
3. To form the channels through which chips can escape from the hole:
This statement is correct as well. As mentioned earlier, the flutes on a drill bit create helical or spiral grooves. These grooves act as channels through which the chips can escape from the hole being drilled. The flutes help to guide the chips out of the hole, preventing them from getting stuck and allowing for efficient chip evacuation.
Therefore, all the statements are correct. The flutes in a drill bit serve multiple purposes, including curling the chips for easy removal, allowing coolant and lubricant to reach the cutting edge, and forming channels for chip evacuation.
