## Questions & Answers

**Q: How difficult is it to get a hole that is in between step sizes? I need a hole that is 30.73mm (1.210 in) and requires a tight tolerance.**
A: Don't expect tight tolerances at all with step bits. Especially if the material thickness is over around 0.05" or so, then you won't even get a cut without a taper.

**Q: Can this be used to rebore the arbor size of circular saw blades? I would like to make the arbor size bigger - 30mm**
A: Yes, the large bit can make a 30mm hole, but I can not vouch for its ability to drill hardened steel.  I used it to drill plastic.

**Q: Would this product work for making a hole on a wooden table??**
A: It would work, but:1) If you go all the way through you would be limited to 3 sizes (max size on each drill)2) If you do not go all the way through, the hole would be stepped and smaller at the bottom.So, if you have wood drills, use them.  If not, then this would work.

**Q: will this work for a black and decker drill?**
A: I use mine on B&D! You do have to back it off from time to time to let the drill catch up... but I dont see why not!

These will definitely serves the purpose for our upcoming projects this Summer. It appear to be a good quality product, sharp and it makes neat and clean holes. This set comes in a small carrying case for safe keeping. Drill bits are on metric sizes which is what my husband is looking for. We are pleased with this purchased so far! For the price, you can’t beat the value.

    Best Deal! Lot less than Ace
  

*by D***H on Reviewed in the United States on November 29, 2021*

Great product for drilling in Lexan. Ace wanted $54 for same drill bit. Completed the job flawlessly.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great for the price.
  

*by S***T on Reviewed in the United States on October 22, 2016*

First off all 3 bits do cut an they do deburr as it cuts. the spiral design is better then the standard design. BUT. The Titanium coating is to thin. After just 1 use most of the coating was warn off. They may not last as long as other bits but because they cut better I may consider ordering again.Update. Have had bits for several weeks now. I use them a few times a week. They seem to be of same quality or better as some $25 step bit sets I have used. I will definitely order again.
