5 Comments on Are Impact Rated Bits Worth the Money?

  1. Great stuff here. I like the calculation of ‘bit cost per screw installed.’

    The “impact rated” bits seem to be at least partially intended to reduce breakage, not just longer tip life. Did you experience much breakage when testing?

    • Exactly. We primarily performed tests that would incur cam-out. Many impact-rated bits are being designed to withstand breaking when performing metal self-tapping applications or similar. The trouble is, that’s not being communicated well, and most people are simply grabbing for impact-rated bits to match their impact driver—which isn’t likely to do much good on standard fastening applications.

      We really need to do a series of follow-up testing that focuses on breakage and proper application and use of an impact-rated bit.

      I am specifically looking for the 1″ insert bits if you have any suggestions of where to buy. I have a normal driving drill (14.4v Dewalt) few years old, looking to buy an impact in the future….. but I am sick and tired of going through drill bits. At Home Depot today, I bought the Milwaukee Shockwave Set ($20 or so) put it one bit, drilled MAYBE 30 screws (1.5″) through ply wood (thick) as sub floor, the bit was completely shot. Returned the set right away. I know in this test the Bosch Ribbed tip and Kobalt Speed fit both scored your highest, will by both to try myself, but have you tried any other brands not tested here (snap-on etc.) that you would recommend? thanks in advance, James
