Frequently Asked Questions

What are the primary applications for taper drill rods?

Taper drill rods are extensively used in rock drilling, creating blasting holes, and other drilling tasks in quarries, coal mines, and various construction or infrastructure projects.

How do I select the correct taper angle for my equipment?

The choice depends on the drilling intensity. Light-duty rock drills typically use a 7° taper or smaller. For heavy-duty applications, 11° and 12° taper angles are the standard choice. It is crucial that the rod and bit share the same degree.

What steel grades are used in manufacturing these rods?

We utilize high-quality steel grades including 95CrMo (equivalent to SANDBAR 20/C253), 55SiMnMo, and 23CrNi3Mo to ensure durability and performance in harsh conditions.

What shank configurations are available?

Our rods come in standard hexagonal configurations, primarily Hex. 22mm and Hex. 25mm, with various shank lengths such as 108mm and 159mm to fit different hand-held pneumatic drills.

What is the range of lengths you can provide?

We offer a wide range of lengths starting from 0.4 meters up to 10 meters, allowing for versatility in different drilling depths and environments.

How are the products protected during shipping?

To ensure the products arrive in perfect condition, we package the taper drill rods in sturdy wooden cases or secure bundles, depending on the order size and transport requirements.
