Locking Sleeves for Removable Drill Bushings
Knurled
Create a permanent base for removable bushings so you can swap them out as needed. These sleeves have a raised flange that slots into the notch on your bushing’s head to lock it in place. Unlike standard sleeves, they don’t require a separate lock screw. Choose a sleeve length that matches the length of your bushing.
Knurled sleeves grip the sides of a hole to prevent rotation. Press or mold them into plastic tooling.

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.
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.
