What is a drill bushing?
A drill bushing – also called a drill guide sleeve – is a cylindrical guide element that is installed in jigs or drill fixtures for precise guiding of dill bits or cutting tools.
They are generally made of hardened steel that is wear-resistant and long-lasting even under heavy loads.
