Circuit-Board Drill Bushings FAQ

Why do PCB drills need special bushings?

Circuit-board drills have a shank larger than the cutting diameter, so the bushing is designed to clear the shank while guiding the small drill.

Do you quote specials to print?

Yes. Send your drawing with material, ID/OD tolerances and quantity. Special bushings, non-standard lengths and other materials are available by special order.

Can you quote ADB, Boneham or ACTEK equivalents?

Yes. Send the Carr Lane part number or your print and we will quote the matching ADB, Boneham or ACTEK bushing alongside the Carr Lane part, so you can compare price and lead time.
