Product Description

Taper drill rod is used for rock drilling, blasting holes and other drilling works in the quarries, coal mines, traffic and other contractions. It works with taper drill bits and has different length for various applications. Our taper drill rods come in a variety of taper angles. Generally, the light duty rock drill usually use 7 taper or smaller taper angle, the heavy duty rock drill mainly use 11, 12 taper angle.

The basic theory is that taper drill rods and taper drill bits must be in the same tapered degree. We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs.

Frequently Asked Questions

1. What materials are used to manufacture these taper drill rods?

The rods are manufactured using high-quality Carbon Steel and specific steel grades such as 95CrMo (equivalent to SANDBAR20 or C253), 55SiMnMo, and others like 40simncrnimo to ensure durability in harsh drilling conditions.

2. How do I choose the correct taper angle for my project?

Generally, light-duty rock drills use a 7-degree or smaller taper angle. Heavy-duty rock drills primarily utilize 11-degree or 12-degree taper angles. It is essential that the rod and bit have the same degree for a proper fit.

3. What are the primary applications for these drilling tools?

Taper drill rods are ideal for rock drilling, creating blasting holes, and supporting operations in quarries, coal mines, traffic construction, and other heavy infrastructure projects.

4. What shank configurations and sizes are available?

We offer a full range of shank configurations, including common sizes like Hex 22mm x 108mm and Hex 25mm x 159mm. Lengths range from 0.4m up to 10m to meet various drilling requirements.

5. How are the products packaged for international shipping?

To ensure safety during transport, our taper drill rods are securely packaged in wooden cases or bundles, depending on the length and quantity of the order.

6. Are the products compliant with international quality standards?

Yes, the manufacturing processes follow GB standards and the production facility is certified under ISO 9001:2000 and ISO 9001:2008 quality management systems.
