The world’s best hole flares?
We looked at the US made hole flares from Mittler Bros., JMR, Pro-Tools and
SWAG and took the best features from all to create what we think are the
perfect hole flare.
Aircraft flares and automotive flares – what’s the difference?
Automotive flares have a radiused transition from horizontal to vertical and
tend to be a deeper flare than an aircraft flare. Because the material is
pressed down into a vertical finish the material is highly stretched. This is
fine for most grades of aluminium but aircraft grade aluminium can be very hard
and if stretched this much, could lead to cracking of the material (not good on
an aircraft!). Because of this aircraft flares were designed and tend to be a
straight fold from horizontal to 45 degrees which is easier on the material but
arguably slightly less visually attractive. The other benefit of an aircraft
flare over an automotive flare is that the thickness of the material doesn’t
come into play. They will produce exactly the same finish on 0.5mm aluminium as
they will on 3mm steel. Automotive flares however, are restricted to the
vertical clearance between the male and female parts of the tool so are only
effective on material thicknesses from 1.0mm – 2.0mm max. You could not
physically get 3mm steel between the tool parts vertically. When we designed
our aircraft flares we added a slight radiused transition from the horizontal
for appearance but left the finish at 45 degrees so they will work with any
material type and thickness. Best of both worlds.
Stakesy’s aircraft hole flares are machined in the UK from 4140 cromoly steel.
The swage angle ranges from 43-45% depending on size. We machined an internal
thread in the female rather than drilling straight through. This negates the
need for a nut and also makes for more accurate docking. Another advantage is
an optional threaded pull rod (available here) to be used with a hydraulic hole
punching machine we sell for flaring material in situ such as vehicle chassis
or roll cage webs (see here for slugbusters).
We machined a flat on the female part so you can hold it in a vice for manual
flaring or for use with a large spanner. All flares come with SKF thrust race
bearings and cap head bolts. This halves the effort required. We recommend the
use of our UK made Q-Max hole punches in conjunction with the flares for ease
of use and accuracy over hole saws. Always deburr the hole first with a rotary
deburrer (see other listings) and use tapping oil or SD42 pressing lubricant
for a perfect finish and tool protection.
Finally, for heavier gauge steels the tool can be used in a workshop press. 3
options; by hand, by hydraulic punch or by workshop press.
