Product Description

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

Key Specifications:
- 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 Angles: 4°46', 6°, 7°, 11°, 12°, etc.
- Length Range: 0.4m to 10m.

The light-duty rock drills usually utilize a 7° taper or smaller, while heavy-duty rock drills mainly use 11° or 12° taper angles. It is essential that the taper drill rods and taper drill bits share the same tapered degree for proper operation.

Technical Note: Shank hex 22 mm (7/8") x 108 mm (4 1/4"). Rod hex 22 mm (7/8). Flushing hole diameter 6.7 mm.

Frequently Asked Questions

What materials are used for the taper drill rods?

Our taper drill rods are primarily manufactured using high-quality Carbon Steel, including grades like 95CrMo (comparable to C253 or Sanbar23) and 55SiMnMo for superior durability.

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

Generally, light-duty rock drills use a 7° taper or smaller. For heavy-duty operations, 11° or 12° taper angles are recommended. Ensure your drill bits match the rod's taper degree.

What shank sizes are available?

We offer standard hex sizes including Hex 22mm and Hex 25mm, with various shank lengths such as 80mm, 108mm, and 159mm to suit different pneumatic drilling needs.

What is the maximum length of the drill rods?

The taper drill rods can be produced in lengths ranging from 0.4 meters up to 10 meters, depending on the specific requirements of the drilling site.

How are the products packaged for international shipping?

Products are typically packed in robust wooden cases or secured bundles to ensure they remain protected and intact during transit.

What is your monthly production capacity for these tools?

We maintain a high production capacity of approximately 500,000 pieces per month to ensure steady supply for large-scale mining and construction projects.
