We design, manufacture and market Special Aircraft Tools. Our most popular items are our Drill Bushing Sets.
We manufacture different types of drill bushings – 3 types. All bushings are machine from O-1 Tool Steel. We maintain a tolerance of ± 0.001”. They are then, heat treated and tempered. We have laser engraved the respective bushing size on the head of the bushing. For each set, we include a tray machined from 6061-T6 aluminum alloy. Anodizing the tray a red color results in a highly visible, wear and corrosion resistance bushing holder. To provide for a more orderly handling and control control, we engrave the bushing size on the tray, at the respective bushing’s location.
Our Most Popular Set
Firstly, our most popular set is the 27 Piece OD Drill Bushing Set (Transfer Bushing). We have designed and selected bushing’s outside diameter is to meet the requirements of fastener holes for standard, oversize and under sized aircraft fasteners. We also produce an 8 Piece OD Drill Bushing Set (Transfer Bushing) to accommodate just the standard size aircraft fasteners.
Interfaces with Drill Bushing Block
The second of the 3 types, we produce a 16 Piece ID Drill Bushing Set (Slip Fit). Machined with OD of 0.500”, the ID (pilot hole) through the bushing varies. We have designed and selected the pilot bores size is to guide drills to produce standard, oversize and undersized aircraft fastener holes. We also produce a 5 Piece ID Drill Bushing Set (Slip Fit) for just the standard aircraft fastener holes. This type of Drill Bushings is designed to interface with our Drill Bushing Block.
Interfaces with Drill Egg Cup
Lastly, we produce a 16 Piece ID Threaded Drill Bushing Set. The ID sizes are identical to the “Slip Fit” bushings noted in item 2 above. However, the OD of these bushings is a ½” 13 TPI NC thread. These bushings have been designed to interface to our Threaded Drill Egg Cup. Again, we can supply this bushing in a set of 5 Pieces for the standard fastener sizes.
We can also sell bushings individually to replace missing or lost bushings.
Finally, we have completed a production run to produce larger Transfer Bushings. A 6-Piece set with outside diameters up to 0.7500” . Also include is a 0.7850” diameter transfer bushing. This size, is purpose designed to assist in the the installation of Brownline seat/cargo track. This set is now available.

2 Responses to “Drill Bushings 3 Types”
I’m looking for a set of OD drill bushings
.098 to .489.
We manufacture and supply a 27 Piece OD Drill Bushing Set (Also known as Transfer Bushings) the Smallest outside diameter is 0.1285″ the largest in the set is 0.5312″.
To be clear this set has different size for the outside diameter of each bushing. The internal diameter of the pilot bore for all bushings with outside diameter of 0.1875″ or less is 0.098 (#40 Drill) all other bushings in the set have an internal bore of 0.1285″. This may not be what you are looking for.
We also make a set of ID Drill Bushings (also known as “Slip Fit” bushings). The outside diameter of all bushings in the set is 0.500″. The inside diameter of the bore varies based on the intended Fastener hole. The smallest diameter is 0.0980″.
Both types are described in detail, including the specific diameters contained in each set, at our online store https://www.sas-canada.com/store. If you have any other questions please email us at tools@sas-canada.com.
