PDC bits are specially designed for fast drilling in shale, limestone, and sandstone formations. They come in two types of bodies: steel body and matrix body. Both types offer the same cutting effectiveness. strickly speak, the matrix body material is more hard than steel body but the strength is not so well comparably with steel body . Each of the body have their own advantage :
The performance of the drill bit is influenced by several factors:
Body material: This refers to the material used to construct the bit's body.
Cutter density: It refers to how the cutting elements are arranged and their quantity on the bit.
Cutter size or type: This describes the size or type of the cutting elements on the bit.
Bit profile: It determines the shape and design of the bit's cutting structure.
