Product Description:
The Tapered Button Bit is an essential component in pneumatic rock
drills and tapered drill rods, which conduct drilling operations
through the connection of the taper on the drill bit and drill rod.
These bits are designed for hard rock drilling and are mainly used
in mine secondary crushing, bolting, drifting, and other related
fields.
The Tapered Button Bits are an upgraded version of the chisel drill
bits and cross drill bits. Thanks to the tungsten carbide tips and
the hot-plated skirts, the tapered button bits provide a good
drilling effect and have a long service life. With their excellent
features, these bits offer a reliable solution for all your
drilling needs.
Conventional taper angles for tapered drill bits come in three
standard options: 7°, 11°, and 12°. The proper angle for your
drilling activities will depend on the type of rock you are
drilling and the specific application in which you will be using
the bit.
Features:
Tapered interface: The interface part of the drill bit is conical,
which allows the drill bit connect with drill rod firmly . It
greatly reduce looseness during the drilling process.
High strength materials: Since the drill bit needs to drill holes
in hard rock, it usually use high-strength alloy steel.
Moreover,heat-treated treatment of drill bits will improve wear
resistance and strength.

Applications:
Due to its unique tapered design and high-strength materials,the
taper button bits performs well in many harsh applications. Such as
mining, tunnel construction, geological exploration, construction
engineering, hydropower engineering, railway and highway
construction. Besides, it can also work in municipal engineering,
environmental protection engineering, etc.
