Frequently Asked Questions
What are taper button bits used for?
Taper button bits are primarily used for small hole drilling in quarrying and mining applications. They are designed to be used with air leg drillers or hand-held jack hammer drillers.
What materials are these drill bits made of?
The bits are manufactured using high-quality Alloy Steel Bar (45CrNiMoV or 50R61) and feature Tungsten Carbide Tips (YK05 or T6) for superior hardness and drilling performance.
What is the advantage of using your tapered bits?
Our tapered bits feature a 30% increase in wear resistance compared to standard bits, leading to a significantly longer service life and better suitability for various rock types.
Which taper angles are available?
We offer multiple tapered connections, including 7-degree and 12-degree angles, to match different drill rod requirements and drilling conditions.
What button configurations are available for the Φ25 shank size?
Depending on the diameter (ranging from 36mm to 43mm), the bits come with 6, 7, or 9 buttons in ballistic or flat face configurations.
Are these bits compatible with standard Hex 25 drill rods?
Yes, these button bits are specifically designed to fit Hex 25 (1 inch) drill rods with long skirt designs.
