Review on Premium Diamond Core Bit Set For Concrete Countertops, Marble, Limestone, And Masonry - 2" Drilling Depth, 5/8"-11 Arbor With 1/2" Chuck Adapter Included by Robert Weeks

This diamond core bit set offers versatility and durability when it comes to drilling through tough materials such as concrete countertops, marble, limestone, and masonry. With a 2" drilling depth, it allows for deeper drilling than most standard bits. Plus, the 5/8"-11 arbor and 1/2" chuck adapter included make it easy to use with a variety of power drills. While the set gets the job done, it falls short in terms of precision. The holes drilled sometimes end up slightly larger than anticipated and with uneven edges, and it can be difficult to maintain a straight drilling line. However, the set makes up for this flaw by being long-lasting and dependable. So, if you're looking for a bit set that can drill through a range of materials with ease, this set may be worth considering. Just be prepared to accept some small imperfections in the finished product.
