What device is used to prevent the drill from drilling too deep into the material?

The drill stop is specifically designed to limit the depth of a drill bit's penetration into the material being drilled. This device can be attached to the drill bit or the drill itself, allowing the operator to set a predetermined depth, ensuring that the drill does not surpass that limit. This is crucial in various applications where drilling too deep can lead to damage, structural compromise, or require extra work to fix.

In the context of assembly mechanics, maintaining precise control over drilling depth is important for achieving correct fastener engagement and ensuring the integrity of the components being assembled. Proper use of a drill stop helps enhance safety and accuracy in the manufacturing or maintenance environments. Other devices mentioned, like the drill depth gauge, might help determine the depth but do not actively prevent over-drilling like a drill stop does.
