I had the opportunity to use a DeWalt 1/4-20 bit and an Autotoolhome bit at the same time. The Autotoolhome beat (https://smile.amazon.com/gp/product/B088T7LP2C/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1) took the lead with a clear lead. I used Tap Magic (https://smile.amazon.com/gp/product/B00065VEP4/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) - highly recommend - for both taps. I also used an impact wrench on both. The Dewalt product became noticeably slower/dumber after just a few tweaks! The rest of the work (12 holes total) the Autotoolhome drill endured without complaint or slowdown. Both cut good threads but I suspect the coating on the Autotoolhome product will extend the life of the product. When I bought this product it was the #1 recommendation. I recommend a coated chisel (or better yet a cobalt bit would be the most durable/coolest) and use cutting fluid!
