Fordia’s line of surface set core bits meets the needs of drilling companies operating in differing ground conditions. With a choice of diamond grades ranging from coarse to fine, and a variety of profiles, choosing the appropriate surface set core bit is now easier than ever.
The following chart describes the main grades if diamonds available. Please note that the grade represents the number of stones per carat (SPC) and not the quality of the stones. Other grades of diamonds are also available for custom orders.
Choose a synthetic diamond tool for a more economical solution or opt for a natural diamond if you need greater cutting ability. For drilling in hard to very hard ground, a diamond impregnated crown is always a good choice. Whatever the case, you can always count on one of our representatives to help you pick the best product for your needs.

A very durable profile that provides good stability. Ideal for ground that is very fractured.
A profile that helps in the recovery of core samples in very fragile ground.
