Tapered button bits are designed for small hole drilling, distinguished from thread button bits used for long hole drilling. These bits utilize a taper match with the rod, making them ideal for air leg or hand-held jack hammer drillers in quarrying and mining applications.
The wear resistance of these tapered bits is increased by 30%, ensuring a longer service life and excellent suitability for various rock types.

Frequently Asked Questions
What is the main application for 36mm tapered button bits?
They are primarily used for small hole drilling in quarrying and mining, compatible with air leg or hand-held jack hammer drillers.
What taper angles are available for the connection?
We offer common tapered connections including 7 degree, 11 degree, and 12 degree angles to fit different rod requirements.
How does the wear resistance compare to standard bits?
These tapered bits are engineered for high performance, offering a 30% increase in wear resistance compared to standard options.
What materials are used in the construction of the bit?
The body is made from premium Alloy Steel Bar (45CrNiMoV or 50R61) with Tungsten Carbide Tips (YK05 or T6).
Can these bits be used in hard rock formations?
Yes, the combination of high-grade alloy steel and ballistic button shapes makes them suitable for a wide range of rock hardness levels.
What is the difference between tapered and thread button bits?
Tapered bits use a friction-fit taper connection for small holes, while thread bits use a screw-on mechanism for long hole drilling.
