Straightrac Drill Bit Features
Optimized Body Profile: The streamlined, non-tapered body design of the straightrac bit is engineered to maintain exceptional hole straightness, especially in challenging, fractured or broken rock formations.
Tungsten Carbide Buttons: Equipped with robust tungsten carbide inserts, these bits offer superior durability and wear resistance. The button shape, like spherical or ballistic, is chosen for specific rock types.
Enhanced Flushing Channels: The design includes effective flushing grooves that efficiently remove rock cuttings from the borehole. This prevents clogging and reduces wear on both the bit and drill string components.
Reduced Sticking in Loose Ground: While similar to the retrac design, the straightrac body is tailored to minimize the risk of the bit becoming lodged or stuck in highly fractured or unstable ground conditions.
Steel Construction: The body is manufactured from high-grade, heat-treated steel, providing the necessary strength and toughness to withstand the percussive and rotational forces of demanding drilling applications.
Straightrac Drill Bit Components
Optimized for Straight Hole Drilling: The unique design of the Straightrac bit, featuring a guide section above the cutting face, helps to keep the drill string stable and aligned. This prevents the bit from deviating, ensuring a straighter and more accurate borehole.
Improved Hole Quality and Consistency: By reducing hole deviation and “spiraling,” this bit provides a more uniform and consistent hole diameter. This is crucial for applications that require precise blast holes or for installing anchors and rebar, where a consistent hole is paramount.
Enhanced Drilling Efficiency and Speed: The stable drilling action of the Straightrac bit allows for higher penetration rates without sacrificing accuracy. Less time is wasted on correcting hole deviation, leading to faster completion of the drilling project and increased productivity on site.
Reduced Wear on Drilling Components: The bit’s guiding mechanism reduces stress and lateral forces on the entire drill string, including the rods and shank adapter. This leads to less wear and tear on the equipment, extending the lifespan of valuable drilling tools and reducing operational costs.
All Drill Rods and Bits
Drill Rods
Shank end rod: A specialized short rod that connects directly to the shank adapter, serving as the first piece of the drill string. It’s designed to absorb the high impact energy from the rock drill.
Hex drifter rod: This hexagonal-shaped rod is a standard component used to transmit both rotation and percussion energy down the hole. Its shape provides a strong grip and excellent power transfer, reducing slippage.
Round drifter rod: A cylindrical rod used for percussion drilling applications, similar to the hex drifter rod. Its smooth, round profile can be beneficial in certain ground conditions and is less prone to binding in the borehole.
Hex Speedrod (MF Rod): Also known as a Male-Female rod, this hexagonal rod features an integrated threaded end for direct connection to the next rod. This design eliminates the need for a separate coupling, streamlining the drilling process.
Round Speedrod (MF Rod): Similar to its hexagonal counterpart, this round MF rod has a built-in male and female thread on each end. It offers a smooth surface and allows for faster, more efficient assembly and disassembly of the drill string.
Drill Bits
Button bit: Characterized by its tungsten carbide buttons, this bit is a highly durable and versatile tool for a wide range of rock formations. The buttons provide a combination of crushing and shearing action for efficient rock breaking.
Straightrac bit: This bit is specifically designed for maintaining a straight borehole. It features a guiding mechanism or “skirt” above the bit face that helps prevent hole deviation, ensuring precision in drilling applications.
Retrac bit: A retractable bit with an outer reaming ring that aids in hole collaring and reaming. It is designed to be pulled back through a pre-drilled hole, which is useful for specialized applications like overburden drilling.
Cross-type bit: This bit has four cutting wings arranged in a cross pattern. It is effective for drilling in medium to hard rock conditions and is known for its durability and resistance to wear, making it a reliable choice.
Dome reaming bit: Used for creating a larger, dome-shaped hole at the bottom of a smaller borehole. This bit is essential for specific applications like rock bolting, where a secure anchor point is required in the rock.
Reaming equipment: This is a broader category of tools designed for enlarging a pre-drilled hole. It includes various types of reamers and bits that help widen the borehole to a desired diameter for different geotechnical or mining purposes.
