A brief description of the diamond core drill bit.
A diamond core drill bit is one of the common drill tools in the drilling industry. It is unlike the roller drill bit and DTH drill bit because it is a hollow drill bit that is used for fetching the earth core sample for geological study. It is like a steel pipe and the diamond steel was fixed on the end. The diameter of a diamond core drill bit will be 60mm – 150mm. The diamond height will be 10mm – 75mm. The total length of the diamond core drill bit is 60mm – 75mm.
The features of a diamond core drill bit.
- The drilling process of a diamond core drill bit is fast and smooth.
- A Diamond core drill bit can be used at a higher temperature to drill through rocks, like quartzite, Jaspilite, Cape Shale, Corundum, Quartz, Flint, and Jasper.
- The special design of a diamond core drill bit will protect the sample well.
