Drill size and travel
Drill presses are measured by twice the distance between their bit and the stand that supports the machine. This is referred to as the swing of the drill push and represents the largest diameter piece the drill can handle. For example, a drill press with a length of 7.5 inches between the stand and the bit would be a 15-inch drill press. Drill travel is how far the drill chuck will go up or down. The greater the travel ability, the deeper the drill push can bore.

Speed
Most benchtop drills offer variable speed drilling, measured in revolutions per minute (RPM). RPMs are important when drilling various types of material, as some require low RPMs while others call for high RPMs. For example, wood is typically drilled at a higher RPM than metal, which needs to be drilled at a lower speed to prevent the bit from overheating.https://neverbroke.club/woodworkingmash
