Threaded Drill Bushings
 |
Skip the lever press—these bushings thread into a tapped hole in your fixture or a hand-held threaded sleeve. You can switch between bushings with different IDs without creating a separate hole. And unlike removable drill bushings, you don’t need to permanently install a sleeve first. These bushings are made to tight dimensional tolerances so you can drill accurately and consistently from part to part.

Corrosion-Resistant Press-Fit Drill Bushings
 |
These bushings are made of stainless steel for corrosion resistance. Mount flush with jig plates for precise drilling. Drill bushings can also be used as spacers, shims, and machinery bushings.
Also Available: Other sizes. Please select 8504A999 and specify ID, OD, and length.
440C Stainless Steel—440C stainless steel is harder than 303 to resist wear. It provides good corrosion resistance.

Slotted Bushings
 |
When locating a workpiece using through-hole alignment pins (sold separately), use one of these bushings and one standard bushing to prevent the pins from binding in your fixture. One pin sits in the standard drill bushing for tight-tolerance locating in all directions, and the other pin sits in the slotted bushing for tight-tolerance locating in only one direction. This functionality is similar to the combination of round and diamond-head locating pins. Press these bushings into a drilled hole for permanent installation. They’re also known as slotted locator bushings.
Slotted Bushings with Etched Line—Check the position of the markings to make sure your bushings are aligned.
Slotted Bushings with Spring Pin—A spring pin helps you align bushings and keep them from rotating. To mount in your fixture, drill one hole for the spring pin, then another for the bushing.

Strong-Hold Slotted Bushings for Plastic
 |  |
With a knurled surface, these bushings grip plastic workpieces tightly so they don't wobble or slip. Use them to prevent through-hole alignment pins (sold separately) from binding while locating workpieces. Your first pin sits in one of these slotted bushings for precise locating in one direction. The second pin sits in a standard bushing for locating in every direction. This setup is similar to the pairing of round and diamond-head locating pins. They're also known as slotted locator bushings.
