Secure-Hold Drill Bushings for Plastic
Designed to grip slippery plastic, the knurls on these bushings keep them from spinning while you drill. Their hold is stronger than serrated bushings, so they can withstand more force. Press or mold into plastic tooling to guide your drill bit and create accurate, consistent holes.

Drill Bushings for Plastic
Serrations line the sides of these bushings to keep them from spinning while you drill. Also known as jig bushings, they’re pressed or molded into plastic tooling to guide drill bits, counterbores, and reamers. They help you create consistent, accurate holes from part to part.

Drill Bushings for Soft Metal and Wood
Serrations on these bushings dig into wood, aluminum, and other soft metals to keep them from spinning while you drill. Also known as jig bushings, they fit inside fixture plates to guide drill bits, counterbores, and reamers. They improve accuracy so that your drilled holes and cuts are consistent from part to part.
