Product Description

Taper drill rod is essential for rock drilling, creating blasting holes, and various drilling operations in quarries, coal mines, and infrastructure projects. Designed to work seamlessly with taper drill bits, these rods are available in multiple lengths to suit diverse applications.

Key Technical Features:

Steel Grade: 95CrMo (equivalent to SANDBAR 20, C253, Z708, sanbar 23) or 55SiMnMo.
Shank Sizes: Hex 22mm x 108mm, Hex 22mm x 159mm, Hex 22mm x 80mm, Hex 25mm x 108mm, Hex 25mm x 159mm.
Taper Angles: 4°46', 6°, 7°, 11°, 12°, etc.
Length Options: 0.4m - 10m.

The light-duty rock drills typically utilize a 7° taper or smaller, while heavy-duty applications require 11° or 12° taper angles. It is critical that the taper drill rods and bits match the same tapered degree for optimal performance and safety.

Frequently Asked Questions

1. What are taper drill rods used for?

Taper drill rods are primarily used for rock drilling and blasting holes in quarries, coal mines, traffic construction, and other mining or building contractions.

2. How do I choose the correct taper angle?

Generally, light-duty rock drills use a 7° or smaller taper angle. Heavy-duty rock drills mainly utilize 11° or 12° taper angles. The rod and bit must always share the same degree.

3. What steel grades are available for these rods?

We provide rods in 95CrMo (comparable to SANDBAR 20/C253) and 55SiMnMo, ensuring high durability and performance in tough drilling conditions.

4. What are the standard shank configurations?

Common shank sizes include Hex 22mm x 108mm and Hex 25mm x 108mm, but we also offer lengths of 159mm and 80mm to meet different pneumatic drilling needs.

5. Can the length of the rod be customized?

Yes, we provide tapered rods in a full range of lengths, typically ranging from 0.4 meters up to 10 meters.

6. How is the product packaged for shipping?

To ensure safe delivery, drill rods are usually packed in sturdy wooden cases or secured in bundles, depending on the length and quantity.
