Diamond Core Bit, the Essential

People who are faced with drilling projects have all the reasons in the world to use diamond core bits. If you have been using this type of bit, then great for you. If not, well now is the time to switch to this high-power diamond cutting tool and see the difference.

Drilling a perfect hole really isn’t so tough of a problem for a diamond core bit, for whatever type of hard material it is used for – be it concrete, granite, marble, etc, however thick or dense it is. You have so much to gain and nothing to lose if you are trying out a diamond core bit for the first time.

 

Here are just some of the benefits of this wonder tool:

Convenient

Because they are much better than ordinary core bits or the old-fashioned spear-point bits, you are definitely getting more than you bargained for. Really, with diamond core bit, it is perfectly right to set your expectations high. In fact, it may just be all you’re ever gonna need for your every drilling project. It also produces little noise so those who easily get annoyed with noisy bits, then here’s the tool for you.

Reliable

Diamond core bits are as tough as they come. As opposed to other core bits that loosen up when applied on the stronger materials, diamond core bits are tough enough because they are made from top-of-the-line materials. They are simply intended to cut through the hardest of material. The ease with which a core bit creates perfect holes may just surprise any skeptic. Even with the speed it is able to finish the job is phenomenal.

Protects health

Believe it or not, diamond core bits are designed to protect the operator from particles that may harm his health. As you know, there are just so much hazards in the construction industry.

Cost-efficient

For the reasons mentioned above, diamond core bits are economical, and this certainly translates to labor savings. Given the materials from which they are made, they are simply a great buy.

These are just some of the reasons why a diamond core bit is a must-have. The various professionals in the construction industry can attest to the efficiency of this amazing tool. Really, you can try asking industry people and I assure you they will answer in unison – the diamond core bit is such a revolutionary cutting tool, and as with many other tools, it is best that you know which type of core bit a specific task calls for.

Tips in Using a Diamond Core Bit

When it comes to drilling holes into materials like ceramics, tile, marble, granite, and other hard materials, core bits are the absolute way to go. A core bit is hollow, and, depends on the manufacturer, can be really strong. The good ones can create a perfect circle, forming a hole. Because diamond is the hardest material there is, diamond core bit makes for a great choice in drilling a hole. Normally, core bits are sold alongside different cutting tools.

If not used properly, a diamond core bit can overheat and can get heat fracture that may result to breakage. Bear in mind that when properly used a core bit should just be warm. Otherwise when it gets hot, it means that the drill speed is fast, or the material being drilled cannot take the pressure, or there is not enough lubrication.

 Here are the basics on the main drilling techniques that you should study before getting your hands on a core bit.

Drill Speed

Because all core bits aren’t equal, this one hugely depends on the power tools manufacturer. There are types that are used at slow speeds and decreases even further for harder and more abrasive materials. On the larger bits, the RPM (revolutions per minute) should be decreased. In prolonging the life of core bits, you should be able to consider low pressure, sufficient water for lubrication and the correct drill speeds.

Drill Pressure

If you increase the pressure on the softer materials, the drill will get faster. As for harder materials, the pressure should be decreased. Just let the core bit do its thing, so to speak. If this isn’t followed, the core bit may get damaged. Light to medium pressure is advisable. 

Lubrication

Any expert will tell you that water should be used to lubricate the tip, and of course, any coolant to cool it down. Water is in fact the best used lubricant because it is most efficient aside from the fact that it is readily available. 

What lubrication does is it makes for a decreased heat buildup, so it helps prolong the life of the core bit. Without question, the importance of lubrication can never be overstated. It is something you would never want to overlook. This holds true most especially if you are using a diamond core bit. There are different methods of lubrication, and this I will discuss in one of my future blogs.
