Special Aircraft Tools – Aviation Sheet Metal Mechanics

We Manufacture Special Aircraft Tools for the Aviation Industry

With over 50 years of experience in the aircraft industry we have make Special Aircraft Tools.  We were asked, about 10 years ago, to produce a set of drill bushings for a reasonably complex requirement.  As a result, we began our production of tools manufactured, produced and marketed for the particular and precise needs of the aircraft industry.  Although these tools are designed and intended for special applications, the advantages these tools provide are not limited just to the aircraft industry.  Furthermore they can be used by anyone, any time an accurately placed drilled hole is required.  In part the procedure can be referred to as “Holemaking“. So, to list our capabilities, we  manufacture drill bushing sets, drill blocks, drilling egg cups, drill stands and drill squares. Images of our tools are shown below:

Drill Block (Special Aircraft Tools)

Another tool offered in the Special Aircraft Tools category is the Drill Block.  Sometimes it is called a Drill Bar or a Snatch Block.  We recently redesigned this tool to include  set screws to hold the slip fit Drill Bushing in each end.  As well as, we have incorporated a “V” Groove in the base to lighten the block and permit accurate drilling of fastener holes on cylindrical or tubular components.
