Torque & Power

The 3/4 -inch drills are meant for hard work, which is worth mentioning. The greater the drill you use, the more power you will require. As a result, the 3/4 -inch drills are more powerful and have a lot of torque.

Torque & Power Comparison

The torque is greater than that of 1/2 -inch to the 1/4-inch drills. It also depends on how much torque the drive can take.

1/2  and 1/4-inch drills are obviously smaller and suitable for lighter tasks. As a consequence, they are not as powerful. However, 1/2 -inch drills are so strong that they can be harmful if not used properly. 

Winner: 3/4 inch drill is better than the rest because of extra torque and power.


When it comes to durability, the 3/4 -inch drill is more durable than the other two drills. 3/4  -inch drills are typically used for heavy-duty applications. As a result, they are built of extremely durable materials.

The 1/2  and 1/4-inch drills are built with weaker material than the 3/4 -inch drill. As a result, they are expected to be less durable than the 3/4-inch drill. However, don’t think that 1/2-inch drills are significantly weaker than 3/4 drills.
