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.

Key Application Theory: Generally, light duty rock drills use a 7° taper or smaller angle, while heavy duty rock drills mainly use 11° or 12° taper angles. The taper drill rods and taper drill bits must share the same tapered degree for optimal performance.

We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs.

Frequently Asked Questions

What are the primary applications of taper drill rods?

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

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

Selection depends on the machine's power: light-duty rock drills typically use a 7° or smaller taper, while heavy-duty rock drills require an 11° or 12° taper angle.

What steel grades are used in your taper rods?

Our rods are manufactured from high-quality steel grades including 95CrMo (equivalent to SANDBAR20/C253), 55SiMnMo, and other durable carbon steel alloys.

Can I use different taper degrees for the rod and the bit?

No. For safe and efficient operation, the taper drill rod and the taper drill bit must have the exact same tapered degree.

What are the standard shank sizes available?

Common shank sizes include Hex 22mm x 108mm and Hex 25mm x 108mm, though we offer various configurations to suit hand-held pneumatic drilling needs.

How are the products packaged for international transport?

Products are securely packed in either wooden cases or bundles to ensure safe delivery and protection during transit.
