True or False: When enlarging the pilot holes, you use a lower RPM drill motor.

Using a lower RPM drill motor when enlarging pilot holes is generally considered best practice because it helps to achieve better control and minimizes the risk of damaging the material or the drill bit. Lower RPMs reduce the heat generated during drilling, which can be particularly important with certain materials to prevent overheating, which may lead to premature wear of the tool or workpiece distortion. A slower speed also allows for better chip removal, ensuring that debris doesn't clog the drill bit and that it maintains its cutting efficiency.

This technique is especially significant when drilling harder materials, as using high RPMs could lead to increased friction, potentially causing the drill bit to dull quickly. Thus, the choice of utilizing a lower RPM for enlarging pilot holes aligns with the goal of ensuring precision, maintaining tool integrity, and achieving a high-quality finish.
