Our Grand PDC bit adopts 16mm claw PDC cutting teeth and large blade design. It can drill medium to medium hard strata. It is recommended to drill shale, mudstone, Cemented Sandstone and carbonate rock with medium compressive strength.
As a leading manufacturer of HDD (Horizontal Directional Drilling) drill bits, we are dedicated to providing our customers with the highest quality products that are designed to deliver exceptional performance, reliability, and efficiency.
These virtually indestructible HDD bits and inserts can withstand all the difficult spots and rough patches that drilling can throw at you. Whether you're drilling in gravel or dirt, Grand Construction has the right directional drill bit or insert for your project.
It can drill medium to medium hard strata. It is recommended to drill shale, mudstone, Cemented Sandstone and carbonate rock with medium compressive strength. We have a large selection of HDD drill bits, such as milled-tooth pilot bits for soft and loose formations. With optimized lining protection, hard metal on the bevel and internal cone discharge, the pilot bits can withstand the harsh drilling conditions typically encountered in HDD applications.
One of the key benefits of our HDD drill bits is their exceptional steering capabilities, which allow them to accurately navigate even the most challenging directional drilling applications. Whether you're drilling beneath a city street or under a riverbed, you can count on our HDD drill bits to deliver precise, reliable performance every time.
In addition to their cutting and steering capabilities, our HDD drill bits are also designed to minimize vibration and reduce wear and tear on your drilling equipment, helping to extend the lifespan of your tools and reduce downtime on your drilling projects.
At our company, we are committed to providing our customers with the highest quality drilling tools and accessories, and our HDD drill bits are no exception. So whether you're drilling for telecommunications, utilities, or oil and gas, you can trust our HDD drill bits to deliver the reliable, high-performance drilling you need to get the job done right.
Unlike conventional PDC-guided bits, our Grand Construction bits offer a number of design advantages, including:
Extended profile design for faster drilling in rock formations.
Built-in stabilizers for improved stability of the drill column.
More PDC tools for longer life than standard PDC drill bits.
Our standard HDD-guided bits are available in 5-1/2" and 6-1/2" sizes. Each bit features our durable and highly respected 5-blade design, including a 13mm PDC tool, for professional, precise and efficient performance in any rock drilling project.
Many traditional milled tooth bits consist of several different parts, resulting in moving parts. However, our pilot bits and reamers are single-piece products made of high-quality alloy steel. They are more robust than any tri-cone milled tooth roll and can be used at very high speeds. This technology greatly increases the amount of drilling that can be accomplished. Operators can work longer and harder without compromising the tool. In fact, it is well known that our HDD drills can drill up to 10,000 feet!
