Shims for Keyed Shafts

Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.

Shim Sets for Keyed Shafts

Be prepared with shims in a variety of thicknesses. Also known as arbor spacers, these shims are notched to fit over keyed shafts.

Unthreaded Spacers for Keyed Shafts

Also known as arbor spacers, these are notched to space components on a keyed shaft.

Drill Bushings

Press-Fit Drill Bushings

Made-to-Order Press-Fit Drill Bushings

Choose the ID, OD, and length you need.

Finish-Your-Own Press-Fit Drill Bushings

Larger OD tolerances than standard press-fit bushings allow for finishing. Bushings should be machine ground.

Metric Press-Fit Drill Bushings

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part.

Made-to-Order Metric Press-Fit Drill Bushings

Choose the ID, OD, and length you need.

Corrosion-Resistant Press-Fit Drill Bushings

These bushings are made of stainless steel, which provides excellent corrosion resistance.

Wear-Resistant Press-Fit Drill Bushings

Made of durable tungsten carbide, these bushings outlast steel.

Metric Press-Fit Drill Bushings with Head

Even under extreme drilling pressure, these metric bushings won't press through your jig plate. A flanged head on the top of the bushing acts as a stop, preventing it from moving as you push down your drill bit, reamer, or other cutting bit.

Press-Fit Drill Bushings with Head

The head prevents these bushings from being pushed through the jig when drilling pressure is extreme. The head sits above the jig plate or can be mounted flush by installing in a counterbored hole.

Made-to-Order Press-Fit Drill Bushings with Head

Choose the ID, OD, and length you need.

Made-to-Order Removable Drill Bushings

Choose the ID, OD, and length you need.

Removable Drill Bushings

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.

Drill Bushings for Soft Metal and Wood

The serrations at the top of the bushing grip to prevent rotation and spin out.

Secure-Hold Drill Bushings for Plastic

The knurls resist force and provide better holding strength than serrations. Encase in plastic tooling.

Removable Drill Bushings for Thin Metal

Insert these bushings into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in in place by a separate locking part.

Drill Bushings for Plastic

The serrations grip to prevent rotation and spin out. Press or encase into plastic tooling.
