Review on 🛠️ Titanium Plastic Aluminum Shank Modifier by Ray Gist

First of all to be clear these are not metric drills. Those are inch drills, but they're marked with metric conversions, which is so stupid I can't even spell it properly. Even transformations are everywhere, and there is no absolute consistency. For example, a 13/64" drill bit (which converts to approximately 5.2mm) is marked "5.0". And then the actual diameter is 4.9mm, so do the math. than the conversion from inches, but meanwhile the 1/4" drill (which converts to 6.3mm) is marked "6.5" and the actual diameter is actually 6.3mm (1/4 "). So what follows is the size in inches, but somehow the label converts to 6.5 and not 6.3. You might think they just round up to 0.5, but that's not the case either, since there's and "4.8" and some "3.2". . There are two drill bits marked "2.5" so they can't be distinguished: one is actually 2.5mm and the other is 2.4mm (equivalent to 3/32 inch diameter). As for why they're both labeled "2.5" your guess is as good as mine. All bits are also coated top to bottom with some kind of sticky coating that stays on your fingers and whatever surface you place them on. They're pretty boring too. Overall pretty useless.
