Abrasiveness is a ground condition that can cause headaches among many drillers. It can be difficult to drill through when present in any hardness of ground.
Abrasive ground and rock can wear down drill bits quickly and in the case of hard abrasive ground, iron ore poses a particular problem and is often referred to as a bit cemetery.
Luckily, there are core bits, such as the HERO Abrasive line, that have been developed specifically for abrasive ground conditions.
These bits have a special matrix consisting of alloys and diamonds that when combined, are very resistant to abrasive conditions and are easy to sharpen in the hardest conditions.
What’s more, their waterways are wider, making it easier to flush out cuttings.
You should consider
waterway configurations that specifically address abrasive conditions.
