Component Drill Bushing
Product Description Guide extended-length drill bits into workpieces to create deep, accurate holes. Also known as gun drill bushings, these bushings are used with gun drilling machines and CNCs. Rather than installing them directly in your fixture, you slide these bushings in and out of sleeves (sold separately). This means you can replace a worn bushing quickly, without damaging your fixture. Swap in a bushing with a different ID, and you can use the same hole in your fixture for a different-sized bit.
