Diamond bits vs. carbide bits

Today, there seems to be a wide variety of tools and bits available for any application, so it can be difficult to decide which option is best to use. For example, I'm sure you know about carbide coring bits and diamond  bits, but which coring bit is best and what tools are available for each type of coring bit? They have both been around for years and different users swear by different ones. Let's see how they compare and which one is the best choice.

Diamond Core Bits

Superabrasive, diamond-plated tools have major advantages over carbide - long-lasting and high cutting rate diamond tools are different from other tools. Initially, diamond tools will cost more money, but this investment is made to extend the life of the drill.

In addition, diamond tools have smaller cutting tolerances than carbide. When used for cutting capabilities, such as diamond hole saws, diamond tools will polish and corrode the workpiece. The smooth effect of diamond tools allows for precise, high tolerance cuts. Higher thermal conductivity is another hallmark of diamond tools. They stay cooler longer and better dissipate the heat generated by friction. This means they don't burn the workpiece and damage it. You can even use diamond tools without coolant and they still won't overheat. This is important to keep your shop clean and free of slip hazards.

To make these bits, the manufacturer uses pressures of up to 1.5 GPa and temperatures of about 1250 degrees (Celsius). The composition of these bits consists of real diamond powder, pressed onto steel using this very high pressure. Diamond, being the hardest substance, retains its strong cutting power after machining and the bits are available in different sizes. The smaller size diamond drill bits are made for small holes for people who make jewelry, watches and other fine jewelry that we often see and other accessories. The larger ones are used for more rigorous drilling activities.

Carbide Core Bits

Carbide bits consist of metal - they are either solid tungsten carbide or have tips covered in tungsten carbide cement. Because of the long life and durability of carbide bits, professionals can use them in many different industries. They are more durable than hardened steel bits, but not as durable as diamonds. As with any metal bit, there will always be wear, dulling and breakage. The good news is that you can sharpen carbide bits to extend their life. However, after performing a few sharpening sessions, there will be no material left behind. In order to work properly, carbide tips need coolant to prevent burning and overheating. It is important to note that coolant mixed with runoff can create a dirty sludge that requires constant cleaning.

How to use diamond drill bits

Diamond bits have different uses depending on their type, but they all have the same principles of use.

Improper use of the drill can lead to damage, material breakage and overheating. That's why it's crucial to know the proper way to use this power tool.

To properly use a diamond drill, you must know the right amount of lubrication, drilling pressure and drilling speed for the material you are using. Knowing this will allow the drill to work properly and eliminate any possibility of overheating due to friction caused by the hard material you are working with. A diamond drill bit in use should not overheat. It may be hot, but getting hot indicates that the drill is heating up and this must be avoided at all costs.

Lubrication (water or coolant) is very important when drilling because it is fitted to the drill tip. It helps to reduce the heat generated during the drilling process, thus avoiding thermal breakage and breakage of the material. Moderate speed and adequate lubrication can extend the life of a diamond drill bit by a factor of 10.
