TAPER DRILL STEEL is a special type of drill pipe material mainly used for small hole drilling operations in geological exploration, mining, construction and other fields. The following is a detailed introduction about TAPER DRILL STEEL:
Structure and Design:
TAPER DRILL STEEL typically adopts a conical design, which helps to better break rocks and soil during drilling and improve drilling efficiency.
The conical drill bit steel combines high-quality impact drill rods and wing designs similar to rotary drill bits, which help to discharge cutting materials from the hole while maintaining the straightness of the hole.
Working principle:
The working principle of TAPER DRILL STEEL is similar to traditional impact drill rods, which apply an impact force at one end to transmit the shock wave to the tungsten carbide rock drill bit at the other end, thereby breaking the rock.
At the same time, the drill bit/steel rod will rotate slightly to break new rock and blow air or air/water mixture into the hole through internal channels to remove cutting material from the surface of the drill bit and flush the cutting material out of the hole.
Features and advantages:
TAPER DRILL STEEL is suitable for harsh geological conditions, especially in situations where rock fragmentation is poor or there are cracks that absorb shock waves. Its design helps to reduce “sticking” and improve drilling success rates.
The conical design and wing structure help maintain the straightness of the holes, reduce deviations, and improve drilling quality.
Suitable for handheld small hole drilling, the length range is usually 0.4-8 meters, and can be customized according to specific needs.
Materials and Manufacturing:
TAPER DRILL STEEL is usually made of high-strength and wear-resistant materials such as stainless steel and high manganese steel to ensure a longer service life in harsh drilling environments.
During the manufacturing process, precision forging and heat treatment processes are used to ensure that the conical drill bit steel has excellent mechanical properties and wear resistance.
Application field:
TAPER DRILL STEEL is widely used in small hole drilling operations in geological exploration, mining, construction and other fields, such as soil sampling, rock drilling, foundation pile hole construction, etc.
Notes:
When using TAPER DRILL STEEL for drilling, appropriate drill bit models and lengths should be selected based on specific geological conditions and drilling needs.
Regularly inspect the wear of drill bits and replace severely worn ones in a timely manner to ensure drilling efficiency and safety.
Follow the correct drilling operation procedures and safety precautions to ensure the safe operation of drilling operations.
H-series models:
H19, H22, H25: These models usually indicate the diameter or size range of the drill bit. For example, H25 may indicate that this model is suitable for drill bits with a diameter of 25mm or similar sizes.
Features: High strength, high wear resistance, suitable for rock drilling and mining operations.
B-series models:
B19, B22, B25: Similar to the H series, The B series also represents the diameter or size range of drill bits.
Features: These models may focus more on specific geological conditions or drilling depths, providing different hardness and wear resistance.
7 degrees, 11 degrees, 12 degrees Model:
These numbers may indicate the taper or angle of the drill bit. Cone is the degree to which the diameter of a drill bit gradually changes from one end to the other.
Features: Different tapers are suitable for different rock types and drilling conditions. For example, a steeper taper may be more suitable for drilling in hard rock, while a gentler taper may be more suitable for drilling in soft rock or soil.
Length range:
The length range of TAPER DRILL STEEL is usually 0.8-8m, and the specific length can be customized according to drilling requirements.

R25 spherical drill bit: a rock drilling tool designed specifically for drift and tunnel excavation
Product features:
This drill bit is designed for soft to medium hardness rock formations and is a high-speed drill bit. It uses spherical tungsten carbide inserts and is known for its excellent resistance to tungsten carbide fracture.
The SHANGIKE drilling equipment allows drilling workers to replace drill bits without replacing drill pipes. If the goal is to reduce hole deviation in small aperture drilling, the driller usually chooses a conical cross-section drill bit. Different taper angles exhibit different characteristics in terms of the “knock out” index – smaller taper angles can effectively prevent drill bit rotation. This drill bit is particularly suitable for drift and tunnel excavation operations.
The main body of the drill bit is made of high-grade steel and processed through advanced CNC machine tools and heat treatment processes to ensure the high quality and durability of the product.

Integral Drill Steel is a professional term in mechanical engineering, specifically referring to a type of drilling tool that integrates a drill tail, drill rod, and drill head. The following is a detailed
introduction to the overall steel brazing:
Definition and structure: Integrated steel brazing is an integrated tool consisting of three parts: the brazing tail, the brazing rod, and the brazing head, which are closely integrated during the manufacturing process to form a complete tool. This design enables the overall steel brazing to have higher strength and stability during use.
Usage: The integral steel drill bit is mainly used in conjunction with rock drills to drill rock holes, and is widely used in mining, hydropower construction, tunnel excavation, mining, rock drilling, as well as engineering fields such as mines, roads, and tunnels. In these projects, the overall steel drill can efficiently complete drilling tasks and improve engineering efficiency.
Advantages: The overall steel drill has advantages such as good transmission performance, improved drilling speed and efficiency. Due to its integrated design, the overall steel brazing is more stable during use, reducing failures caused by loose or detached components. In addition, the material of the overall steel brazing is usually high-strength steel, which has high wear resistance and corrosion resistance, and can adapt to various complex working environments.
Models and specifications: There are various models and specifications of overall steel brazing, such as B22 and B19 models. There are also multiple options for the types of drill bits, including straight and cross shapes. The length of the drill rod can be adjusted according to specific needs, ranging from 0.5m to 9m. There are also various sizes available for drilling, usually between 23mm and 43mm.
Usage and supporting equipment: The integral steel drill is usually used in conjunction with pneumatic rock drills, which drive the integral steel drill for drilling operations through the impact and rotation forces of the rock drill. Integrated steel drills are mainly used in fields such as quarrying and shallow hole rock drilling, and can meet the requirements of different engineering projects for drilling depth and accuracy.
SHANDIKE offers leading strength and penetration rates, ensuring excellent straightness and hole cleanliness for maximum drilling performance, ultimately saving on fuel costs. Additionally, SHANDIKE can customize its products according to customers’ specific length requirements, either based on samples or drawings. Our taper rod, crafted from high-quality steel and heat-treated, is suitable for hard rock drilling, effectively transmitting impact energy into the rock with minimal energy loss. Furthermore, button bits, compared to tapered chisel bits and tapered cross bits, boast superior technology, a significantly longer primary drilling time, and higher drilling efficiency.
