I used to use a Dremel to make openings in plastic boxes. There was no way to guide the cutting wheel and the plastic will melt into a mess.These were so easy. They make the perfect(!!) holes in plastic. I just pre-drill a small pilot hole and let these go in at low speed. How I have lived this long without these bits I had no idea.So beautiful!
Works for what I needed! Idk his long these will stay sharp. But for the small projects I have they are perfect. I made 24 smallish holes through sheet metal for bolts to go through for vents on the trailer. And two bigger holes through thicker sheet metal to install trailer lights.
This set has all the sizes you would need for most every project. Good for 1/4 inch steel. I will be using using this set for years to come. Cuts fast and clean. I use them with my drill press to make the holes.
You pay alot of money for a high quality set of step bits and i didn t want to spend that much so i chose these ones. They didn t disappoint I used them on a number of construction projects and they actually exceeded my expectations.
Sharp and drill good I ve been drilling truck frame rails with them work great.
This is my second time purchasing this set. They are great quality for the price.
I own a small business and do some sheet metal work. I have NEVER owned any of these before. PRETTY HAPPY. They went through 16ga steel fairly easily. I WOULD RECOMMEND first drilling a 1/8 pilot hole to preserve the tool. It is easy to resharpen a drill bit.
I ve tested these out on several different materials like sheet-metal and plastics and they do a very good job they bore the holes with ease although I suggest a starting hole with a regular drill bit if you re looking at accurate placement of where you want the hole to be.
Installing a receiver hitch on a truck and had to drill 8 holes through the frame. Was really impressed with how quickly it bored through the metal and didnt dull after the 1st hole. Kept its edge and actually impressed me
I have used it several times and it functions well. It is just what you need to drill holes of various sizes.
Good set and working nicely.I use mostly on aluminum . Leave a nice clean hole and automatically ease the edge of the hole. Works great.
