Metal and Plastic Drill with Titanium Coating Review

Do not use on steel. They are too brittle, overheat and break even when coolant is used. I used an old Ctaftsman but it cut the same steel as butter.

They are cheap and very brittle. They break very easily. Lighter than normal bits. The only positive thing I can say is that they hold the lead but be prepared to cycle through all 10 bits.

I think if you just need something to punch holes in wood or plastic they'll be fine, but we're in the middle of an assembly vehicle and hundreds of 1/8" holes to be drilled in sheet aluminum and rectangular steel tubing. These drills were only good for about a dozen holes in aluminum plate before dulling, and fewer than a dozen holes in steel each. I won't be buying them again, for what we're trying I'm happy to spend more on bits that can drill steel more efficiently.
