12 Degree Carbide Tungsten Tapered Button Bit Small Hole Rock Drilling Tools
Product Description
Tapered button bit, also known as taper drill bit, is a specialized drilling tool with wide applications in mining, tunneling, and construction engineering. Designed specifically for rock drilling and blasting operations, it works with both handheld and mechanical rock drills.
This tapered button bit is primarily used with pneumatic rock drills and tapered drill rods, connecting via the tapered interface. Ideal for hard rock drilling applications, it excels in mine secondary crushing, bolting, and drifting operations. As an advanced alternative to chisel and cross drill bits, it features tungsten carbide tips and hot-plated skirts for superior drilling performance and extended service life. Available in standard taper angles of 7°, 11° and 12°.
Key Features
- Tapered interface: Conical connection ensures firm attachment to drill rods, minimizing looseness during operation
- High-strength materials: Constructed from premium alloy steel with heat treatment for enhanced wear resistance and durability
- Impact resistant: Engineered to withstand high-intensity impacts and vibrations in demanding rock drilling applications
