Product Description

Taper drill rod is widely used for rock drilling, blasting holes, and other drilling applications in quarries, coal mines, and infrastructure construction. It works seamlessly with taper drill bits and is available in various lengths.

Generally, light-duty rock drills utilize a 7° taper or smaller, while heavy-duty rock drills primarily use 11° or 12° taper angles. It is essential that the tapered rods and drill bits share the same 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.

Steel Grade: 95CrMo (equivalent to SANDBAR20, C253, Z708, Sanbar23) or 55SiMnMo.
Shank Sizes: Hex 22mm × 108mm, 22mm × 159mm, 22mm × 80mm, 25mm × 108mm, 25mm × 159mm.
Taper Degrees: 4°46', 6°, 7°, 11°, 12°, etc.
Length Range: 0.4m - 10m.
Flushing Hole: 6.7mm diameter.

Frequently Asked Questions

What are the primary uses for tapered drill rods?

Tapered drill rods are primarily used for rock drilling, creating blasting holes, and other pneumatic drilling tasks in mining, quarrying, and construction projects.

How do I choose the right taper angle for my project?

Light-duty rock drills typically use a 7° or smaller taper angle, while heavy-duty equipment generally requires an 11° or 12° taper angle. Ensure your drill bits match the rod's taper degree.

What materials are these drill rods made of?

They are manufactured from high-quality carbon steel and alloys such as 95CrMo, 55SiMnMo, and 40Simncrnimo to ensure durability and resistance to wear.

What are the standard shank sizes available?

Standard shank sizes include Hex 22mm (7/8") and Hex 25mm (1"), with lengths varying from 80mm to 159mm to fit different pneumatic tools.

What is the production capacity and packaging for shipping?

We have a production capacity of 500,000 pieces per month. Products are securely packed in wooden cases or bundles to prevent damage during international transport.

Can I get different lengths of tapered rods?

Yes, we provide tapered rods in a full range of lengths starting from 0.4 meters up to 10 meters to suit various drilling depths.
