True or False: A common rule for drilling through metal is that the larger drill bit should use a slower feed rate of the drill.

The statement is true because when drilling through metal using larger drill bits, a slower feed rate is generally recommended to ensure both the effectiveness of the cutting process and the longevity of the drill bit. Larger drill bits have more surface area in contact with the material, which increases the heat generated during the drilling process. Slower feed rates help to dissipate this heat, reducing wear on the drill bit and minimizing the risk of overheating, which can lead to bit failure or damage to the workpiece.

Additionally, a slower feed rate allows for better control over the drilling process, leading to cleaner and more accurate holes. It also helps prevent excessive pressure on the drill bit, which can cause it to bind or break. Therefore, using a slower feed rate when employing larger bits is a standard practice in metalworking and contributes to optimal drilling performance.
