Core Drill Bit for 4 3/4" (x 2 9/16") oil core barrel complete system with accessories core sample drilling

Introducing our latest innovations in core drilling technology – PDC core bits and diamond impregnated core bits. These two products are designed to meet the various drilling needs of professionals in different industries.

4 3/4" (x 2 9/16") core barrel (complete system with accessories) + compatible PDC bit
7 1/8" (x 4") core barrel (complete system with accessories) + compatible PDC bit

Description
The PDC core bit is a powerful drilling tool designed for drilling through hard surfaces such as granite, quartz and reinforced concrete. Its polycrystalline diamond compact (PDC) cutting technology ensures faster, more efficient drilling while reducing bit wear. This product is ideal for engineers and builders as it can significantly reduce the time and cost required to complete drilling projects. PDC core bits are available in a variety of sizes to meet different drilling needs.

The diamond-impregnated core bit is a versatile drilling tool for hard and soft surfaces such as marble, limestone, and sandstone. Diamond impregnation on the bit ensures longer lasting and efficient drilling while minimizing wear and tear on the bit. This product is suitable for geological explorers, miners, etc. It is designed for ease of use and is compatible with most drilling machines. Diamond impregnated core bits are available in a variety of sizes to meet different drilling needs.

In conclusion, our PDC core bits and diamond impregnated core bits are the perfect combination of innovation, technology and efficiency. They meet different drilling needs and provide excellent performance, making them a must-have tool for any professional looking to undertake a drilling project. Invest in these reliable drilling tools to increase productivity, save money and improve quality.

Core Drill Bit sizes from OD 4 1/2" to 11 5/8";

The standard sizes are 4 1/2", 5 7/8", 6", 7 7/8", 8 1/2", 8 3/8", 9", 9 1/2", 10", 10 5/8", 11".

The advantages of using our core drill bits
1. Arc crown design and blade arrangement have higher ROP, high rate of core recovery and longer service life.
2. Service life of bit can be improved by using PDC cutters and diamond complex gage.
3. Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
4. Diamond ID&OD gage, course set on ID gage to ensure a better cleaning and cooling of the bit.
5. Force balance technology is designed and bit's stability is improved to prevent the bit from premature failure normally.
6. High quality PDC cutters are employed and cutters placement technologies are optimized so that the bit has higher ROP.
