This small-sized carbide drill bit is specifically designed for coal mining applications. Featuring carbide cutting teeth measuring 14mm × 11mm × 5mm (length × width × thickness), it excels in small-diameter, shallow hole drilling operations in soft and medium-soft formations.
The alloy consists of rectangular cemented carbide cutting teeth securely fixed to the drill bit body using advanced brazing and inlay techniques. Constructed from YG9C/YG11C wear-resistant cemented carbide, this material provides an optimal balance of hardness and impact resistance. The matching drill bit diameter ranges from 27-32mm, with this specific model designed for 27mm applications.
Performance Advantages
Efficient Cutting Performance: The 11×14mm cutting teeth provide optimal contact area for rapid penetration in coal and rock formations, even with low-power drilling rigs. Ideal for shallow-hole, high-frequency operations.
Enhanced Durability: High hardness and wear-resistant carbide teeth combined with a stable cutter body structure deliver 1.2-1.5 times longer lifespan compared to conventional alloy teeth, significantly reducing downtime for replacements.
Compact Design & Compatibility: The small size design enables operation in confined spaces while maintaining universal connection specifications compatible with most small coal drills and anchor bolt drilling rigs.
Versatile Drilling Options: Available for both dry and wet drilling applications. Wet drilling effectively reduces dust and improves working conditions, while the optimized chip removal groove design minimizes drill bit jamming and tooth breakage risks.
Designed for high-efficiency cutting, exceptional wear resistance, and superior adaptability in coal mining environments.
