Review on 🔪 Efficient Cutting Plastic with HIDOTOL Titanium Coating by David Robinson

I first ordered this set of step drill bits for drilling small holes in ¼" plexiglass. As soon as it arrived I threw something on the old drill press and within seconds I had a perfect hole in the plexiglass and tiny shavings all over the table.This worked great.Before ordering them I first used a standard drill bit I had in my toolbox (not a wood drill bit) and it heated up the plexiglass very quickly and melted the Shavings as it were causing the bottom of the plexiglass to explode and hairline cracks forming on the underside. These graduated bits were perfect and didn't cause any errors. My only issue with one of the three bits is that it's so small that the engraved and printed one Writing is so hard to read Yes it is a small area but the black ink has faded so much it is off looks like it's a used bat... Otherwise it's a must have set, highly recommend! Oh, and it comes with a cute little case to keep the edges nice and sharp. Hope that was helpful!
