the tool that doesn't push the bolt loose, it punches it loose
means A power tool that loosens or tightens stubborn fasteners by delivering rapid, high-torque rotational blows rather than steady turning force.
from A plain compound of "impact" and "wrench." "Impact" comes from Latin "impactus," the past participle of "impingere" — to strike or drive into — built from "in-" (into) plus "pangere" (to fasten or fix); the word "wrench" is much older and homegrown, from Old English "wrencan," to twist or wrench. So the name is almost a literal description of the mechanism: a twisting tool that works by striking, the hammering hidden inside its spinning.
