Frequently Asked Questions

Q1: What are the primary applications for tapered button bits?

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

Q2: What materials are used in the manufacturing of these drill bits?

Our bits are constructed from high-quality 45CrNiMoV alloy steel bars, featuring premium tungsten carbide tips (YK05 or T6) for enhanced durability.

Q3: Which tapered connection degrees do you provide?

We supply various tapered connections, including 6-degree, 7-degree, 11-degree, and 12-degree systems to match different drill rod requirements.

Q4: What is the difference between a cross bit and a button bit?

Cross bits are widely used for hard rock and fractured rock conditions in mining and tunneling, while button bits offer faster penetration and longer life in most standard rock drilling scenarios.

Q5: How many buttons are typically on a tapered button bit?

Depending on the diameter and specific requirements, the quantity of buttons usually ranges from 5, 7, to 8 pieces per bit.

Q6: Can these bits be used with air leg drills?

Yes, these tapered button bits are specifically designed to be used with air leg drills or hand-held jack hammers for efficient rock penetration.
