Strong-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.
Also Available: Other sizes. Please select 3379A999 and specify ID, OD, and length.

Drill Bushings for Extended-Length Drill Bits
 |
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.
