Drill is a strong, durable cotton fabric with a strong bias (diagonal) in the weave. It can be used unbleached, although it is more often bleached or dyed.
The lighter weights are used in such clothing items as shirts, safari jackets, blouses, playwear, and martial arts wear.
Khaki drill is made into uniforms; boatsail drill is made into sails for sailing craft and is unbleached; drill is also made into pocket linings.
Drills with a percussive action (such as hammer drills, jackhammers or pneumatic drills) are usually used in hard materials such as masonry or rock.
A drill press (also known as pedestal drill, pillar drill or bench drill) is a fixed style of drill, which may be mounted on a stand or bolted to the floor or workbench.
Mill drills are a lighter alternative to a milling machine, they combine a drill press (belt driven) with the x y co-ordinate abilities of the milling machines table and a locking collet that ensures that the cutting tool will not fall from the spindle when lateral forces are experienced against the bit.
