2. Introduction to the product
Advantages:

1.It has a super long life. The useful life of the PDC
  bit is 4~5 times than the diamond bit, 10 times than
  the tungsten carbide bit at least.
2.It has high drilling speed.
3.It can be operated with low pressure and low speed.
4.It has a good package protection.
5.It can be used widely, more suitable for drilling in
  the stratum with hardness coefficient
Product description:
114-117,
Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bits type this hard facing completely covers the bit teeth.

127
Medium-Hard Formation Tooth Bits
The 127 bits are used to drill high-compressive strength, medium hard formation. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.

437
Soft Formation TCI Tricone Bits
The 437 TCI bits are used to drill low compressive strength,very soft formation. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, result in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.

HY517
Medium formation TCI Tricone Bits
This 517 bit features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability, such as:shale, clay, sandstone, soft limestone

HY637
Medium-hard Formation TCI Tricone Bits
The 637 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added cutting structure durability in medium or hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability, such as: hard shale, limestone, sandstone, dolomite.

HY 737
Hard Formation TCI Tricone Bits
The 737 bits can be used to drill compressive strength, hard and abrasive formations. Wear-resistant tungsten carbide inserts are used in outer rows to prevent loss of the bit gauge. Maximum number of the hemispherical-shaped inserts are used in all rows to provide cutter durability and long life, such as:limestone, dolomite, malmstone, chert.
