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.

Frequently Asked Questions

Q1: What are reaming drilling tools primarily used for? A: They are used to enlarge a hole to a larger diameter after a pilot hole has been drilled to the required depth.

Q2: What materials are these drill bits made of? A: They are manufactured using premium carbon steel and high-quality tungsten carbide (Yk05 or T6) for maximum durability.

Q3: Are these tools compatible with different rock conditions? A: Yes, different types of bits are specifically designed to handle various drilling scenarios and rock conditions efficiently.

Q4: What thread sizes are available for the reaming bits? A: Standard thread sizes include R25, R28, R32, R35, T38, T45, and ST58, depending on the specific model.

Q5: Why is the "hot-mounted" feature important for alloy buttons? A: Hot mounting ensures that the alloy buttons are securely and accurately fixed, significantly improving the bit's service life and drilling precision.

Q6: What industries benefit most from these reaming tools? A: They are widely used in tunneling, mining, quarrying, and general construction blasting works.
