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.

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.

Get a good grip on your lock ring to quickly and easily secure removable drill bushings into your fixture plate.

Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves.
