Drill bit drilled 2 holes in 1/4 inch steel and is showing damaged. Holes were drilled in .250 inch steel angle iron on a 5x8 trailer to add LED lights. The drilled holes were stepped up from 1/8 inch, to 1/4 inch, to 1/2 inch, and finally with this 18.5 mm. Tap Magic (cutting/tapping) fluid was used with all the drill bits. But this is a cheap drill bit so I will get the better bits next time. I don't recommend this item.

Used this on 1/8th CRS stepping up to 1-1/8th before using this bit. Never made it through the steel. May us it again in a mill at work, but was not impressed at all
