7/11/12 Degree Tapered Drill Rod For Rock Drilling

7/11/12 Degree Tapered Drill Rods for Rock Drilling are specialized tools designed for use in various rock drilling applications. These rods feature a tapered design, which allows for efficient penetration of hard rock formations. Here are some key points about these drill rods:

Tapered Design: The drill rods are tapered at a specific angle (7, 11, or 12 degrees) from the shank to the tip. This taper provides several benefits, including improved stability, easier penetration of hard rock, and reduced wear on the drill bit.

Material: The drill rods are typically made from high-strength steel alloys that can withstand the rigors of rock drilling. The steel must be able to resist abrasion, wear, and impact forces encountered during drilling operations.
Thread Connection: The rods feature threaded ends that allow them to be connected to each other and to the drill bit. These threads must be precisely machined to ensure a secure and reliable connection.
Length and Diameter: Drill rods come in various lengths and diameters to accommodate different drilling depths and hole sizes. The choice of length and diameter depends on the specific application and the requirements of the drilling operation.
Applications: These tapered drill rods are commonly used in mining, quarrying, construction, and other industries where rock drilling is required. They can be used with various types of rock drills, including jackhammers, pneumatic drills, and rotary drills.
It’s important to note that the specific angle of taper (7, 11, or 12 degrees) may vary depending on the manufacturer and the intended application. Different taper angles can provide different drilling characteristics and performance. Always refer to the shandike manufacturer’s instructions and specifications for accurate information.
