Frequently Asked Questions

What is the main application for tapered button bits?

Tapered button bits are primarily used as small hole bits for air leg or hand-held jack hammer drillers. They are ideal for quarrying, mining, and tunneling operations.

What materials are these rock drill bits made of?

They are manufactured using high-quality alloy steel bars (45CrNiMoV) and premium tungsten carbide tips (YK05 or T6) to ensure durability and a long service life.

Which taper angles are available for connection?

We offer various tapered connections including 6-degree, 7-degree, 11-degree, and 12-degree angles to match different rod specifications.

How many buttons are typically on a tapered bit?

Depending on the diameter and design requirements, our bits usually feature 5, 7, or 8 ballistic or flat face tungsten carbide buttons.

What is the difference between a cross bit and a button bit?

While both are used for rock drilling, button bits use carbide inserts (buttons) for crushing rock, whereas cross bits utilize a four-point chisel design. Cross bits are specifically effective in certain rock formations and for maintaining hole straightness.

What shank sizes are compatible with these bits?

Commonly compatible shank sizes include Φ19, Φ22, and Φ25, typically used with Hex.22mm and Hex.25mm drill rods.
