Stakesy’s® Automotive Style Punch and Flares

The world’s best punch and 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 automotive style punch and flare tools available anywhere.

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 which is straight and angled down at 45 degrees. Because the material is pressed down into a vertical finish the material is highly stretched so is not recommended for highly critical structural positions such as aircraft wing ribs in hard non-malleable grades of aluminium. For aircraft use please see our other listing for aircraft style flares. The design of automotive flares means there is a vertical clearance between the male and female parts of the tool of 2.2mm which makes them suitable on steel, stainless steel, titanium and aluminium to 2.0mm. For flares in material over 2.0mm see our aircraft flare designs on another listing.

Stakesy’s® automotive style punch and flares are machined in the UK from 4140 cromoly steel. The replaceable punches have a tolerance press fit and are machined from D2 tool steel which is then vacuum hardened and tempered resulting in the gold finish. The punch has a 3 prong cutting face that deforms the ‘slug’ against the stepped female cutting face making it easily removable without having to pry it out. This makes for faster repeat use on repetitive flaring. We machine 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 to be used with a hydraulic hole punching machine available for flaring material in situ such as vehicle chassis or roll cage webs (see below for knockout kits & pulls rods)

We machine a flat on the female part of the tool so it can be held in a vice for manual flaring or for use with a large spanner in situ. All Stakesy’s® Automotive Punch and Flares come with SKF® thrust race bearings and the highest quality Unbrako® cap head bolts. This removes friction and halves the effort required to punch and reshape the material. We recommend the use of our SD42 pressing lubricant for a perfect finish and tool protection.
