As an avid DIY-er, I found this step drill to be a complete game-changer in my toolbox. This Industrial and Scientific cutting tool is top-notch regarding both efficiency and durability. As a result of using this product, i found that it creates precise holes in minimal time with minimal effort while the titanium coating ENSURES it lasts longer than regular bits .The only con is that it may be slightly pricier than some alternatives, but the benefits are definitely worth the extra investment. I wholeheartedly recommend it!
