Description of Bosch ITDESQ225B Impact Square Double Ended
10x life over standard impact bits. Xtended torsion zone helps to absorb high-torque of new impact drivers. Precision-engineered tips for a tighter fit and less CAM out. Heat-treated manufacturing for stronger bit. High-visibility sleeve with laser-etched markings for user convenience.
When I tried this product, it failed miserably in drilling through metal. Despite being marketed as an industrial and scientific tool, it did not live up to its promise. The only positive aspect of this product is its double-ended design, which unfortunately doesn't make up for its poor performance in actual use. Save your money and invest in a higher quality drill bit that can handle heavy-duty jobs....
I had to replace a few boards on my deck with this type of screw head. I searched the whole store and couldn't find it. I ordered them and the screws just popped out of the deck boards. They worked just as well when I installed the new boards as they screwed in the 3" screws with no problem.
