As a hesitant buyer in the Industrial and Scientific field i was anticipating promising results, but this product completely missed the mark! As a result of using this product, I found that it didn't last long enough to make a dent even in the most superficial surfaces. The only small pro of this product is its initial ease of use. However, it`s not worth the investment in the long run, as the cons heavily outweigh the pros. Save yourself time and money and look for a more dependable option..
Pros
Durable carbide tipped material ensures long-lasting use.
Cons
Requires specific tools for use, limiting versatility.
Had to cut 72 6" holes through 1/8" plaster and 1/2" plywood. I used it on the Hole Hawg and it never missed a shot. The last hole went through just as easily as the first. I thought it was a bit pricey when I bought it, but it did the job and kicked some serious ass in the process.
