Screw-machine-length drills are 5/8 as long as normal jobber-length drills.
Screw-machine-length drill bits are shorter than jobber-length.
Sometimes called stub-length drill bits, they provide more strength and rigidity and can drill straighter holes than longer drill bits. Their short length also allows them to access tight spaces where longer drill bits cannot fit.
