As diamond drilling experts, we’ve spent years learning and refining our craft. We’ve made the beginner mistakes years ago, so we know exactly how to avoid them now! Here’s some of the common diamond drilling mistakes (and how to avoid them) – implement these tips to become a better, more effective diamond driller. 
Using the wrong bit 
Probably the most common mistake that people new to the trade make is they use the wrong bit. One way to avoid this is to do your research first – understand what you’re going to be drilling into, how big a hole you’re going to need to make and the kind of depth you’ll be drilling to. 
There’s no point turning up with a spade bit if you need a hole saw! 
Getting your speed right 
Faster drill speed doesn’t mean more efficient drilling. The purpose is to work at a speed where the bit can grip the material being drilled, taking off enough material each time. If you work too fast, you can glaze over the material and the bit can’t grip enough material to make a cut. 
Likewise, if you drill too slowly the bit can get stuck whilst trying to cut and not actually take any material off. Getting the speed right will correct these issues. 
Allowing the drill bit to overheat 
One of the most important aspects of high speed, hard material drilling is temperature regulation. If you allow the bit to overheat, or the drill itself to overheat it can shut the operation down. Maintaining a reasonable temperature will improve the drill efficiency and get the job done quicker. 
It’ll also make your tools last a lot longer too! 
Keeping surfaces and bits clean 
This is something you really need to take care of before you start the job. Making sure your tools and bits are clean and well maintained is the first point to address, but ensuring the surface about to be drilled is clean, prepped and ready is also very important. 
By prepping your surface ahead of the drilling you’ll make for a quicker, cleaner and easier job for yourself. 
Making sure the drilling is well lubricated 
Any surface requiring a powerful diamond drilling operation is going to create heat and potentially cause corrosive damage to tooling. One of the ways this can be prevented is by using an appropriate lubricant. Water helps to prevent unnecessary friction, keeps temperature down and makes the process easier. 
Avoiding mistakes always makes the job easier! 
These are the most common mistakes most people will come across in the diamond drilling industry, and if you can follow this advice you’ll avoid them, making you faster and more efficient, plus it’ll save you a lot of money in the long run because you won’t have to keep replacing tools and drill bits!
