uxcell 1/2" Reduced Shank Drill Bits 16mm Black Nitride Coated High Speed Steel HSS 6542, Twist Drill Bit for Stainless Steel Alloy Metal Plastic

I needed to cut a hole on the enclosed trailer door for my peep hole. It drilled the hole with ease and I was done with the project in less than ten minutes. Drilled right through the sheet metal and foam.

23mm drill bit was shipped and arrived promptly for a project.

Then this is the drill you want and need. I know...some people think drills are interesting but having purchased one I now think they're just boring tools.

very durable, sharp drilled 72 holes and it still held it's edge

I purchased 3 of these for a project and thought i could get by. But NO all three dulled within 1 or 2 holes. Very soft and not hardend at all. Out the cost of my purchase, Junk do not buy, spend more and get something you can use, i wished i did.

It will drill a hole.... This thing wobbles like crazy in my drill press. Spend the extra money and get something better if you plan on using it more than one time and want accuracy. Wish I could upload a video of this thing chucked in my press.

more shallow angle is better for metal cutting. I made shallow angle cutting point.

Was using some 3/4" black iron pipe for a woodworking project and this 27mm bit is the perfect size for a snug fit for the pipe.

The item will not last long to be expected
