Impregnated Diamond Core Drill Bit

Description:
This core drill bit is the most commonly-used in the mineral exploration fields. They are used to drill medium to ultra-.hard earth layers. The basic construction of the impregnated diamond core drill bits is a powdered metal crown that is fused to a steel tool body. The powdered metal crown is composed of two layers: the "matrix" layer used to cut the rock and the "backing" layer which joints the matrix layer to the steel tool body.

Features:
1.The impregnated diamond core drill bits features drilling speed and long service life.
2.The design of more cutting edges makes drilling progress more smooth
3.During the manufacturing process, the diamond is free from erosion and fully utilized.
4.The impregnated diamond core drill bits are of various configurations and meet the various needs of local conditions.
5.It offers the most widely-used bit matrices as well.
6.With various specifications, our series matrix range provides an easy selection and reliable foundation for your drilling needs
7.Triple-tube bits are used with Boart Longyear triple-tube core barrels. The face of the triple-tube bits discharges waterways and core lifter case forces the drilling fluid to the bit face. The core can be recovered and inspected in a good condition.

The impregnated diamond core drill bits are available in abrasive, standard and competent formulations.
Abrasive drill bits are for broken, abrasive drilling conditions or for harder rock
Competent bits are free-cutting for fast penetration in very hard rock or used on low-powered rigs and in geo-technical applications.

Our bits can be classified into: crown, round, flat, discharged, and gear type. The standards of our impregnated diamond core drill bit include the Q series standard, DCDMA standard, and Sweden Standard.
