Product Description

Reaming drilling tools are essential components used when a larger diameter hole is required after a pilot hole has been drilled to a specific depth. Our product range includes pilot reaming drilling tools, domed reaming button bits, and adapter reaming button bits.

While pilot reaming drilling tools are composed of separate pilot adapters and reaming button bits, both the domed and adapter reaming button bits feature a robust one-piece design for integrated performance.

Technical Parameters:

Thread size: R25, R28, and R32
Pilot adapter head diameter: 26mm to 40mm
Pilot bit degree: 6°, 12°
Reaming button bit diameter: 64mm to 225mm
Reamer button bit degree: 6°, 12°

Frequently Asked Questions

What are reaming drilling tools used for?

They are used to enlarge a pre-drilled pilot hole to a larger diameter, which is essential for blasting duties in mining and tunneling.

What materials are used in your reaming bits?

We use high-quality carbon steel for the bit body and premium tungsten carbide (Yk05 or T6) for the buttons to ensure maximum durability.

What thread sizes do you offer?

Our standard thread sizes include R25, R28, R32, T38, T45, and ST58 to fit most common drilling rigs.

Can these tools be used in hard rock conditions?

Yes, our reaming button bits are specifically designed with different alloy configurations to handle various rock conditions, including hard and abrasive formations.

What is the difference between pilot reaming tools and one-piece bits?

Pilot reaming tools consist of a separate adapter and bit, allowing for more flexibility, while domed/adapter reaming bits are a solid one-piece design for increased rigidity.

What is the production capacity for these tools?

We have a robust manufacturing capability of up to 500,000 pieces per month to meet large-scale industrial demands.
