Product Description
8 1/2'' 215 217 Milled Steel Tooth Tricone bits
 
The tricone bits are used to drill all kinds of formations, from soft to hard. The softer formations use steel-tooth bits, and the harder use tungsten carbide.<o:p>

The biggest advantage the tricone bits have over any other drill bit is the test of time. They have been proven time and time again, and they're the best at controlling the trickier situations. Tricones' ability to handle both soft and hard formations gives them the flexibility that other drill bits do not have.<o:p>
