A taper drill bit is a specialized rock drilling tool which work with tapered drill rods and a pneumatic rock drill machine like YT28 for a small hole drilling. This design enables efficient energy transfer from the drill to the bit, making it suitable for breaking and penetrating hard rock surfaces. And it has three types: taper button bit, taper chisel bit as well as taper cross bit. Then how to choose the taper bit type?Bellow are the details:

What Is A Taper Drill Bit?

Key Features:

• Tapered angle: The drill bit end has a specific taper angle (e.g., 7°, 11°, or 12°) to match the rock drill rod or equipment.
• Material: high-grade steel and tungsten carbide for durability and high wear resistance.
• Type Design: Chisel type,cross type and button type
• Sizes: Available in different diameters (e.g., 25mm to 50mm) and lengths depending on the depth and diameter of the required hole.

How To Choose A Taper Drill Bit?

Taper Button Bit

Tapered button bits mainly work for medium-hard to hard rocks, such as granite, basalt, etc. These rocks are relatively hard, and ordinary drill bits are easily worn during the drilling process. The carbide buttons of button drill bits can effectively crush rocks. In mining, when ores with a hardness of 6-8 on the Mohs hardness scale, the crushing effect is more obvious.

Taper Cross Bit

Cross drill bits generally work for soft to medium-hard rocks, such as shale and sandstone. Its cross-shaped cutting edge design allows the drill bit to effectively cut into the rock during rotary drilling. For rocks with a certain layered structure such as shale, the cross drill bit can cut along the layering direction. So as to reduce drilling resistance. For example, in some small stone quarries, when mining sandstone with a Mohs hardness of 4-6 for construction materials. Then the cross drill bit can play a better drilling performance.

Taper Chisel Bit

Contact us to discuss your requirements of Tapered Rock Drilling Tools. Our experienced sales team can help you identify the options that best suit your needs.

Taper chisel bit mainly work for soft rocks, such as clay rock, mud rock, etc. Its cutting edge is simple in shape, and it can break the rock like cutting when drilling in soft rock. For rocks with lower hardness, such as clay rock, the drilling speed of chisel bits is relatively fast. For example, in some mining sites, when mining clay rock with Mohs hardness of 1-3, it can drill efficiently.
