BMLC NMLC HMLC Diamond Core Drill Bit and Reaming Shells

Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability. According to the cutting media on the reaming shells. At present, Forsun makes five types of reaming shells, it includes:

• • ---Surface set Diamond Type
  • ---Impregnated Diamond Type
  • ---Tungsten Carbide Type
  • ---PCD Type
  • ---Electroplated Diamond Type

Depending on the cutting media, Forsun makes four types of Casing & Casing shoe & Rod Shoe Bits:

• ---Impregnated Diamond Casing & Casing shoe & Rod Shoe Bits
• ---Surface set Casing & Casing shoe & Rod Shoe Bits
• ---Tungsten Carbide Casing & Casing shoe & Rod Shoe Bits
• ---Electroplated Diamond Casing & Casing shoe & Rod Shoe Bits

Impregnated Diamond Core Bits are manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.
