Our Ultra Value core bits provide a good quality bit, with a high quality of industrial diamonds, at an economical price. They can be used in dry coring applications and are the solution when a jobsite has no water supply, or when it is not practical to use water. 
The tube of the core bit is solid, which minimizes silica dust during use.

Core bit dimensions are listed in the format:

Diameter x Drilling Length x Thread Connection

For Example:

2” x 10” x 5/8"-11

• 2” – The nominal diameter of the hole the core bit is designed to drill
• 10” – the usable drilling length (max drilling depth of the bit before an extension is required).
• 5/8"-11 – The connection that attaches the core bit to the drill. This must match the spindle on your core drill or the adapter being used.

Smaller diameter core bits (typically under 2” in diameter) can have a 5/8” - 11 threaded connection.

The bits have a drill depth of 9” and connect to your drill with a 5/8”-11 shank. We also offer a 6” bit extension, if needed.
