Removable Drill Bushing Sleeves
 |
Avoid wear caused by repeatedly pressing bushings into your jig fixture. Instead, press fit these sleeves into the fixture one time, and then swap bushings with different IDs in and out to change the size of your bit. Also known as type L headless liner bushings, they're sized for use with removable drill bushings (sometimes called slip-fixed and renewable bushings). Made of hardened steel, they won't wear as you slide the bushings in and out.

Multipurpose Low-Carbon Steel Round Tubes
 |
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit.
DOM—DOM (drawn over mandrel) welded tubes are stronger than ERW (electric resistance welded) tubes.

Wear-Resistant Nylon Round Tubes
 |
Because these wear-resistant nylon 6/6 tubes have a slippery surface that reduces friction, they’re often machined into bearings, gears, and valve seats.
Oversized Tolerance—Oversized tubes have an oversized OD and an undersized ID for finishing to the sizes listed.

Telescoping Delrin® Acetal Round Tubes
 |
Telescoping tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing also allows ascending sizes to fit inside each other to increase the wall thickness.
Easy to machine to close tolerances, these dimensionally stable tubes resist expanding when exposed to heat and moisture. They have a naturally slippery surface along with excellent wear resistance. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Telescoping UHMW Polyethylene Round Tubes
 |
Telescoping tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing allows ascending sizes to fit inside each other to create a thicker wall. These impact- and wear-resistant tubes offer 360° protection from scrapes and strikes to wires, cords, and anything that can slide through them. UHMW has a low-friction surface that resists sticking and binding.
