Staying sharp makes a lot of business sense

If you spend your hard-earned money on drill bits that have to be constantly replaced, then you’ll start wondering if you can’t get better value elsewhere. The answer to this problem is a comprehensive range of grinding equipment. Maintaining penetration can therefore save you money.

 

Firstly, you need good grinding equipment for a start – and you won’t find any better than Epiroc´s. And secondly, you need to spend time and energy grinding your bits. But the rewards are significant. For a really small investment of your overall drilling costs, you can restore your worn bits to their former glory. And with these bits you cut the time and manpower needed to drill the hole. In fact, you will reduce overall drilling costs. How? By using the market’s widest selection of efficient, ergonomically designed grinding machines for fixed installations and field operations – Epiroc grinding machines.

Get the sharpest advice

In a drill bit grinding machine, the grinding wheels are composed of abrasive compounds. Grinding wheels life span can vary from less than a day to many years, depending of the release of individual grains, dull growing and that they increase drag pulls out of the bond. The process of manufacturing the grinding wheels is therefore a controlled and precise process and is necessary for good performance.

 

There are many different types of bits, some with inserts and others with buttons – and they come in many different sizes. To further complicate matters, no two rocks are the same. Consequently, bit wear differs. There’s only one good piece of advice we can give you – don’t make a decision before talking to us. And remember, thanks to Epiroc´s extensive service network, a good regrind is only a phone call away.
