### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great bits
  

*by D***N on Reviewed in the United States 🇺🇸 on January 22, 2023*

Used bits to drill through 1/4 inch mild steel while replacing wooden decking on my 20 ft car hauler. I orders the 10 pack thinking I would dull or break some while drilling the 100 holes. No I have 9 brand new bits left and the only one I used still cuts like it’s new . Best bits I have ever used
