Impregnated diamond core bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer contains a uniform distribution of these crystal that are embedded in a powdered metal bond.
We possess professional ability of WL/ Q series drill bits and reaming shells. Our drilling bits have first-class quality , excellent performance. Bits and reaming shells are designed on basis of ground condition. In respect of drilling in speed and useful life,our products are the most competitive products in China.
Shapes of lips: flat-bottom,circular,serration,pointed teeth,angle teeth,ladder,and ladder with end spray .
Standard: To cooperate with Q series drilling tools,bits are designed on basis of different stratum condition. Ourcompany also design and produce non-standard drilling bits according to customer's special requirements.
Recommendation: When hardness of stratum is high,low grade drilling bits are recommended to ensure matching of stratum.
Size:BWL, NWL, HWL, PWL etc.Also, non-standard sized bits can be produced according to requirements from clients.
Crown Height:
we offers crown depths of 10mm, 12mm, 14mm.The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance. Unless otherwise specified, a standard 14mm impregnation depth is supplied for most of our customer.
Waterways:
Various waterways are available for diamond impregnated bits.Differing waterways allow for better flushing in various ground conditions and drilling systems.
Matrix hardness:
For convenience of customer from different countries, Sinocoredrill impregnated bit matrices adopts the international standard matrix number system. Matrices to be used on various rock conditions can be ordered according to the MATRIX SELECTION CHART.
Threads:
Standard DCDMA threads as well as thread types required by clients are available.
Specifcation of Diamond core bits
Main features:
1. Greater resistance to wear in most formations, particularly in the extremely hard rock formation.
2. Less sensitive to abuse, rough handling and improper use.
3. Self sharpening owing to the erosion of matrix and the diamonds.
4. Synthetic diamonds of high quality which are distributed evenly throughout the matrix.
5. Efficient cutting function provided by fresh, sharp diamonds continually.

How to select the diamond core bits?
When selecting a bit there are 3 main factors that contribute to decision making.
○ Rock Hardness
Measured using MOHS hardness scale: The Mohs scale of mineral hardness is a qualitative ordinal scale that characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material.
○ Rock Formations
Rock types are classified by their different chemistry and structure. Hardness in theory is relative; therefore, soft rocks can prove more difficult to drill than hard rock. Also, the same rock formations, in different locations, can drill differently.
Factors that Determine Drillability
① Grain Size
② Rock Hardness
③ Weathering and Fracturing
○ Bit Characteristics
Matrix – Each of the matrices has a different rate of wear. The matrix chosen is ideal when there is a balance between the wear of the matrix material and the diamonds exposing ensuring a high rate of penetration and optimum bit life.
Gauge – The outer (hole) and inner (core) dimensions of the bit.
Crown Height – Ranging from 4mm to 14mm in height. With higher crowns available upon request. The height of the crown is chosen based of hole depth and wear rate.
Waterways – There are multiple different waterway configurations depending on the drilling conditions.
