Best Diamond Drill Bit For Granite: Deal with Stone, Metal, Tiles and Rocks Too

Have you ever had the pleasure of working with Granite? If so, the chances are that you would definitely know how nightmarish it could be to drill through that stuff in one piece. To chew through something that hard and tough, you would need something strong, something versatile, something that could really take a beating – you would need something like a custom-made best diamond drill bit for granite. In this article, I am going to introduce you to a bunch of diamond tip drill bit for stone models that are clearly going to answer the question “What is the best way to drill through granite?”

Granite can be a very tough thing to crack, especially if you aren’t using tools that are custom made for it like Dremel diamond bits for stone and the likes. Normal drill bits can somewhat get the job done – I assure you, however, that’s only viable if you don’t really mind chewing through all of them in a fortnight or less.

What I am trying to say is that, if you are going to drill in to granite using a concrete drilling machine, there is no real way to get around the fact that you would need to invest in a set of good diamond coated drill bit models or diamond drill bit set that are better suited for the job. In this review/buying guide on the best diamond drill bit for granite models, I am going to let slip my takes on the absolute best granite hole cutter and drill bits variants you can buy right now.

The Best Diamond Drill Bit for Granite vs. Tungsten Carbide for the Same

Let’s face it, a good set of the best diamond drill bit for granite can be a rather expensive thing to own. However, when compared with its less durable tungsten carbide or cobalt alternative, the diamond coated ones can easily seem like a better deal all around

For one: a diamond drill bit for granite can last a lot longer than any of its other alternatives like carbide or cobalt made ones. Coated with naturally occurring carbon crystal, the diamond core bits for granite drill tops are obviously much stronger and can withstand abrasion and heat much better than any other man-made hard bit models can.

Moreover, the overall aesthetics and finishing that you would get with a best diamond drill bit for granite will hugely be better than any other tool or bit you can think of. The lines would be crisper, the edges sturdier and the chances for chipping too would be on a bare minimum level.

Secondly, the best diamond drill bit for granite can be used to drill through a wider array of materials and surfaces than any other can. From steel to glass, wood to marble, and ceramic to tile, there isn’t really a place where these drill bits aren’t useful or effective.
