    Exceptional tool

    3 months ago
    I have two of these they worked so good that I bought a second one. This tool is underrated. I've not seen a job or workload that this tool has not been able to handle. A+

    Yes, I recommend this product.

    Solid semi-professional breaker

    8 months ago
    This hammer has been a workhorse for us for years. It was the only sds-max option that was available in my area at the time. It has no active vibration reduction so its not the easiest on your body but its done everything from a 6in paddle for tile removal to point chisels for breaking out 6in slabs. Super solid hammer, 5 years of commercial flooring use and its still going strong. Its been our main breaker for the whole time so its seen some hours. Keep it greased and dont let it get too hot, and it lives on. Hopefully they didnt change anything on the newer tools, for the price you pretty much can't do better. The only difference between this and my "professional" hilti breaker is the weight and vibration. It is our secondary breaker now but still keeps slappin.

    Yes, I recommend this product.

    [This review was collected as part of a promotion.] Bought this hammer drill two years ago and it still goes through concrete like a hot knife through butter. Other brands just don’t stand up. And the bits stay sharp hole after hole.
