Bench And Long-Hole Drilling ST58 (2 1/4″)

When discussing “Bench and Long-Hole Drilling ST58 (2 1/4″)”, we are typically referring to a specific type of drill rod or drill steel used in mining, quarrying, and similar industries. Here are some key points about this type of drill rod:

1. Diameter: The “2 1/4″” refers to the diameter of the drill rod, which is 2 1/4 inches (or 57.15 mm). This diameter is common for bench and long-hole drilling applications.

2. Bench Drilling vs. Long-Hole Drilling:

   • Bench Drilling: This typically refers to drilling shorter holes, often from a raised or “bench” position, to remove material for excavation or blasting.
   • Long-Hole Drilling: Involves drilling deeper holes, often to set explosives for blasting large areas of rock.

3. ST58 Material: The “ST58” designation likely refers to the material grade or specification of the drill rod. Different grades of steel have different properties, such as strength, toughness, and wear resistance, which are important for specific drilling applications.

4. Features: Drill rods used for bench and long-hole drilling are designed to withstand the high forces and vibrations encountered during drilling operations. They often have threaded ends to allow them to be connected to other rods or to the drill bit.

5. Applications: These drill rods are commonly used in mining and quarrying operations to create blast holes or for other excavation work. They can be used with various types of drills, including pneumatic, hydraulic, and electric drills.

6. Safety Considerations: When using drill rods for bench and long-hole drilling, it is important to follow safety protocols and procedures. This includes wearing appropriate protective equipment, ensuring the drill is properly maintained, and adhering to industry standards and regulations.

It’s important to note that the specifications and properties of drill rods can vary depending on the manufacturer and application. Always refer to the manufacturer’s instructions and specifications for accurate information.
