Diamond grit hole saw drill bit sets are a terrific choice because of their low price and unusually impressive list of benefits, not to mention the fact that they have a diamond-topped tip that will endure for a very long time.

In addition to the cutting edge’s sharpness, the diamond coating can make grinding a more enjoyable experience. The drill bits come in a pack of five and are available in a variety of sizes.

8. SQB Diamond Drill Bits Set
- Quality
- Our Rating
The drill bits are made of high-grade stainless steel and have adequate resilience to withstand “impact” action, making them perfect for breaking down stone materials. A hole on the side of each drill bit prevents dust and debris from accumulating.
It also aids in the cooling of the drill bit by allowing lubricant to flow freely for a smoother, heatless drilling motion. These hardened drill bits performed admirably in our tests, even outperforming some of the other items on this list.
These drill bits are only advised for usage between 800 and 1000 RPMs, which makes cutting rather sluggish. But when it works, it works well.
The cuts are well-made. There are no scrapes or breaks. These drill bits may also be used to cut tile, porcelain tile, ceramic tile, brick, and stone.
Pros
- 1. Corundum edges are extremely sharp and long-lasting
- 2. Very durable
- 3. A perfect drill bit for granite
- 4. A large 15-piece drill bit set is ideal for cutting through glass

Frequently Asked Questions (FAQs)
Diamond drill bits, which are designed to eat through granite like butter, might be a great addition to your toolkit. However, it is an expensive investment. As a result, it’s reasonable if you’re concerned about them.
Here are some commonly asked questions concerning diamond drill bits, along with their responses, to help clear the air.
What is the expected lifespan of these drill bits?
Though it varies on a variety of circumstances, the typical diamond drill bit can drill up to 1200 holes, with more expensive ones drilling up to 2000 holes.
What else can I do with it except cutting Granite?
These diamond-like drill bits may also be used to drill holes in porcelain, glass, stone, marble, and other hard materials. In fact, you can use them to cut through sapphire and porcelain. That is, assuming you’re willing to chew through a few more parts.
Can they withstand hammering?
Other models are unknown to us. The ones we’ve shown you thus far, though, are all backed by hammer action. In fact, some of them include strengthened teeth to make the action more consistent and forceful.
Do they really feature real diamonds?
They don’t, in fact. Because of their diamond-like crystalline structure, these drill bits are commonly made from a combination of tungsten carbide and diamond polycrystalline.
To put it another way, they do contain a little amount of diamonds. However, it’s not enough to merit the inclusion of the former’s name.
Is lubrication still required?
Yes, absolutely! They may be tough, but they’re just as awful at heating as other drill bits. As a result, if you want a clean, cool cut, lubrication is usually a good idea, especially when working with metallic things.
