FAQ

Q: What speed do you need to drill a diamond core?

A peripheral speed of 2.7 to 4.7 metres/second (9 to 15.5 feet/second) measured on the outside diameter of the bit crown will often provide an acceptable rate of penetration (ROP).

Q: How to sharpen a diamond core drill bit?

Pour into kerf a thick (1/4") layer of silica sand, the coarser the better. Resume coring for approximately 3 to 5 minutes with very little water and at a lower RPM if possible. Gradually increase water flow to flush sand from kerf. Repeat as needed.

Q: Will a diamond core bit cut through metal?

Diamond drills can cut through almost all materials, including some of the toughest materials such as concrete, metal, and glass.

Q: Which is stronger, carbide or diamond?

Diamonds remain the most scratch-resistant material known to humanity. Metals like titanium are far less scratch-resistant, and even extremely hard ceramics or tungsten carbide cannot compete with diamonds in terms of hardness or scratch-resistance.
