Review on 🔧 20-Piece Hex Head Allen Wrench Drill Bit Set - Metric and SAE S2 Steel Hex Bits with Magnetic Tips - 2.3" Long in Storage Box by Chad Black

These hex bits are slightly smaller than the listed dimensions. With It started slipping with a 2.0mm bit. The 1.5mm bit didn't even catch the set screw I tried it on. I took my calipers and took some quick measurements of these bits and drivers, the I traditionally use. The 2.0mm bit from this set only shows 1.9mm on my calipers, while my regular set (not sure of brand. Maybe Dynamite?) reads at 2.0 tot. The 1 .5mm bit from this set is only 1.4mm while my regular screwdriver is 1.5mm Also the tips of these bits are slightly rounded which (in my experience) when used with RC bolts results in that the bits slip when they don't t * straight * are at the right angle. I'll try sanding down the rounded tip and try again. For around $12 I can't complain too much but I wouldn't recommend these bits for use with RC equipment.
