Bench And Long-Hole Drilling T38 (1 1/2 “)

Bench and long-hole drilling T38 (1 1/2″) are terms referring to a specific drill rod diameter that is commonly used in mining, quarrying, and similar applications. Here are some key points about this type of drill rod:

1. Diameter: The “1 1/2″” (38.1 mm) refers to the outer diameter of the drill rod. This diameter is selected based on the specific needs of the drilling operation, including the type of rock, the depth of the hole, and the drilling equipment being used.
2. Material: T38 drill rods are typically made from high-strength steel alloys that are designed to withstand the rigors of drilling operations. These materials are chosen for their strength, durability, and resistance to wear and tear.
3. Applications: T38 drill rods are commonly used in both bench and long-hole drilling operations. Bench drilling typically refers to shorter holes drilled from a raised or “bench” position, while long-hole drilling involves drilling deeper holes for blasting or other excavation purposes.
4. Features: These drill rods often have threaded ends that allow them to be connected to other rods or to the drill bit. They may also have other features, such as a tapered design or special coatings, that improve drilling performance or extend the life of the rod.
5. Safety: When using T38 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 drilling equipment is properly maintained, and adhering to industry standards and regulations.
