Product Description

Reaming drilling tools are used when a large diameter is needed to be reamed out after a pilot hole is drilled to a depth. We manufacture pilot reaming drilling tools, domed reaming button bits and adapter reaming button bits. Pilot reaming drilling tools consist of pilot adapters and reaming button bits; however, both domed reaming button bits and adapter reaming buttons bits are one-piece designed.

●

Parameters

Frequently Asked Questions

Q1: What is the primary use of a Reaming Bit? A: Reaming bits are specifically designed to enlarge a previously drilled pilot hole to a larger diameter, which is essential for various blasting and construction tasks.

Q2: What materials are used to ensure the durability of these bits? A: Our reaming bits are manufactured using high-quality Carbon Steel and premium Tungsten Carbide (YK05 or T6) buttons for maximum wear resistance.

Q3: Which thread sizes are commonly available? A: We offer a variety of standard thread sizes including R32, T38, T45, and ST58 to fit most common drilling rigs.

Q4: How are the alloy buttons attached to the drill bit? A: The alloy buttons are hot-mounted into the drill bit body, a process that ensures high accuracy, prevents button loss, and increases the overall lifespan of the tool.

Q5: In what environments are these reaming tools most effective? A: They are ideal for heavy-duty drilling in tunneling, mining, quarrying, and civil construction projects where efficient hole enlargement is required.

Q6: Are there different designs for different rock conditions? A: Yes, we offer different configurations (pilot reaming, domed, and adapter types) to optimize performance based on specific drilling scenarios and rock hardness.
