Best for: Auto body technicians, metalworkers, and DIYers doing sheet metal repairs.
The SUNEX TOOLS SX278C is a pneumatic punch flange tool designed for auto body work and metal fabrication. It punches 8mm holes and simultaneously forms flanges in sheet metal up to 14-gauge, saving time versus separate steps. The head rotates 360 degrees, which makes it easy to work in awkward positions around panels. The comfort grip sleeve keeps the tool secure in your hand even with greasy gloves. On the downside, this tool is air-powered, so you need a compressor that can deliver at least 4 cfm at 90 psi. That limits it to a workshop setting - no cordless freedom. But for anyone doing regular bodywork or HVAC ducting, the speed and consistency are worth the hose. 26 (76% off the original price), this is a steal. 52, so you're saving over $100. If you already have a suitable compressor, this tool pays for itself in one or two jobs.
The current price of $32.26 is well below the 30-day average of $132.86 and the 90-day average of $134.52. With a 76% discount, this is an exceptional deal. The all-time low is not recorded, but this price is unlikely to last long.
It handles up to 14-gauge steel, which is about 0.0747 inches thick. It can punch, crimp, and flange in one operation.
You need a compressor that delivers at least 4 cfm at 90 psi. A standard 1/4-inch air inlet fitting and 3/8-inch ID hose are recommended.
It is designed for edge piercing and flange forming. For blind holes, you would need a different punch type.
