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.

The slug may be easily removed thanks to the side hole that was drilled into it. Its nickel plating, which gives it an industrial look and feel, will help it last longer and be more reliable than a standard brass drill bit set.

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.

They are constructed to universal standards, so there will never be an issue with them not fitting. 3/8-inch shanks and a 3-inch cutting depth make these drills ideal for work where both precision and speed are critical.



Number 2


Many of the standard drill bits on the market today aren’t specifically designed for drilling holes in porcelain tile and glass, and they mostly lack the necessary precision. Unlike granite; where physical force and basic power are important.

Diamond-coated heads make this 10-piece diamond drill bit for granite set from Drillpro very accurate and extremely long-lasting, as well. You may use it to cut crisp lines from sensitive materials like glass or tiles because of its tiny diamond dust incorporated in it.

The Drillpro diamond drill bit for granite features a side-punch-out for faster and simpler slug removal as a low-cost option that keeps to the basics. This specific set depends heavily on abrasion to accomplish its goals.

It’s not the cheapest set of drill bits, but it’s certainly not the most expensive either. But for the price, you get a lot of features like cored center shanks and slug holes, diamond-dust coated edges, and nickel-plated glossy shell, which is a nice touch.

This set of 10-diamond drill bits for granite is ideal for drilling into weak materials like glass, porcelain, marble, and tiles, and is ideal for more delicate operations and missions.

To be clear, this is a combination drill with three speed settings for both drilling and hammering through granite.

There are two features that make this 20V MAX Cordless 1/2 in. Hammer Drill stand out from its competitors: the ratcheting metal chuck with carbide inserts, and the brushless motor that provides up to 75% greater runtime than a traditional brushed motor.

In addition to a three-mode LED, it is 20 times brighter than the previous generation. Each of these components, the battery and the charger, must be purchased separately.

It has a solid feel because to the metal and high-quality materials used in its construction (the chuck is metal too). The only drawback is that it is heavier than normal, weighing in at 4.4 pounds.



Number 5


Carbon steel with a nickel-plated finish is used to make it strong and durable. As you can see, the resistive force of this glass tile drill bit is set at its lowest possible setting in order to facilitate drilling ultra-precise holes in the matter of seconds.

Efficiently creating a high accuracy and clean cut that actually leaves no chipped edges or cracked ends thanks to the edged hole-high-quality saw’s diamond coating

It should be noted that the shanks are solid and not hollow. That’s why you may or may not like it, depending on your own personal preferences, because it has a light weight to it. Best Diamond Drill Bit Set has 15 various sizes, making it the best value for money option we’ve found today.

Number 7


The Blendx diamond drill bit for granite and glass is electroplated to increase its endurance, but it has a shine that may not reflect how excellent its edge and performance are.

These diamond core drill bits for glass are designed particularly to suit low drilling rates and are ideal for all those delicate applications where precision and refinement are more important than raw power.

The drill bits may benefit from the sealed shanks. The additional wide lubrication and slug removal holes, on the other hand, actually give a great touch of convenience to this completely steeled up thing.



Number 8


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.



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.
