SHAANXI HAINAISEN INTELLIGENT EQUIPMENT MANUFACTURING CO.,LTD presents the 30mm Half Blade Anchor Bit For Mine Coal Fields, engineered specifically for underground coal mining support operations. This precision-Manufactured anchor drilling tool features 1304 PDC cutters and M14X1.5 connection threading, delivering exceptional performance across strata levels 1-12. With over 10 years of PDC cutting technology expertise and a production facility spanning 6,000 square meters, our company combines advanced manufacturing capabilities with rigorous quality standards. Our technical team of 20+ senior engineers ensures each bit meets the demanding requirements of modern mining operations, providing reliable anchoring solutions that enhance workplace safety and operational efficiency.
Advanced PDC Cutting Technology
The anchor bit utilizes polycrystalline diamond compact technology, where diamond particles are sintered with metallic binders under extreme pressure and temperature conditions. This manufacturing process creates a superhard cutting surface capable of withstanding the rigorous demands of coal field drilling.
Your drilling operations benefit from enhanced wear resistance and extended tool life. The half blade design optimizes cutting efficiency while maintaining structural integrity during continuous operation. This configuration proves particularly effective in the softer to medium-hard formations commonly encountered in coal mining environments.

How to Choose the Right Bit
Start with your hole sizeUse the 30mm standard bit for most roof bolting applications.If your anchor rod requires a different diameter, we can customize from 20–45mm.
Match the rock hardness
- Soft to medium coal seams (Grade 1–6): Standard half-blade with 1304 PDC works perfectly.
- Hard, broken rock (Grade 7–12): Choose a reinforced version with upgraded cutters or full-blade design.
Check your rig connectionConfirm your drill rig’s thread size.M14×1.5 is common, but we can adjust to fit your equipment exactly.
Prioritize your needs
- Fast drilling speed: Stick with the half-blade design.
- Tough, abrasive formations: Upgrade to full-blade or higher-grade cutters.
Key Performance Advantages
Enhanced Durability
Your operations experience reduced downtime thanks to the superior hardness of PDC materials. The diamond-enhanced cutting structure resists abrasive wear significantly better than conventional tungsten carbide alternatives.
Cost-Effective Operation
While the initial investment may exceed traditional bits, the extended service life and faster penetration rates deliver substantial cost savings over time. You'll complete more anchor holes per bit, reducing tool replacement frequency and associated labor costs.
Optimized Blade Configuration
The half blade design strikes an ideal balance between cutting aggression and stability. This geometry facilitates efficient chip evacuation while maintaining directional control during anchor hole drilling. Your operators will appreciate the consistent performance across varying geological conditions.
Versatile Application Range
The 30mm Half Blade Anchor Bit For Mine Coal Fields handles multiple coal mining support tasks, including roof bolt installation, cable anchoring, and reinforcement drilling. The adaptable design accommodates different rock compositions within the specified strata range.
Application Scenarios in Coal Mining
Roof Support Installation
Your safety systems rely on properly installed anchor bolts. This bit drills precise holes for roof support anchors, ensuring secure attachment points that meet regulatory compliance standards. The reliable penetration rate maintains project schedules without compromising hole quality.
Roadway Reinforcement
Coal mine roadways require systematic support to prevent ground instability. The bit's efficient drilling capabilities enable rapid deployment of anchor mesh support systems. You can establish comprehensive ground control measures that protect personnel and equipment.
Gas Drainage Operations
Proper gas drainage is critical for mine safety. Our anchor bits create accurate boreholes for drainage pipe installation, supporting effective methane management strategies that reduce explosion risks and improve ventilation conditions.

Material
Our bits are crafted using premium-grade materials, including:
- High-strength steel body for durability
- Tungsten carbide inserts for superior wear resistance
- PDC (Polycrystalline Diamond Compact) cutters for enhanced cutting efficiency

Quality Control
At HAINAISEN, quality is our top priority. We implement rigorous quality control measures throughout the manufacturing process:
- Strict raw material inspection

FAQ
Q1: Why is this bit appropriate for use in coal fields?
A: For coal measure rocks, PDC cutter technology and half blade geometry work best together. When you come across tougher bands, which are frequently seen in coal seams, you maintain durability while getting effective cutting action in softer formations.
Q2: What are the advantages of drilling operations with the 1304 PDC cutter configuration?
A: Cutting speed and tool longevity are balanced in this cutter standard. In order to minimize vibration and improve hole straightness, which is essential for anchor installation, the size and location maximize force distribution throughout the bit face.
Q3: Is it possible to alter the connection threading?
A: Absolutely. Although M14X1.5 is our usual arrangement, different thread requirements can be accommodated by our production capabilities. Without the need for adapter hardware, you may match the bit connection to your current drill equipment.
Q4: What range of stratum hardness is represented by "levels 1-12"?
A: Formations ranging from very soft coal and clay to medium-hard sandstone and limestone are included in this group. One bit type can be used in a variety of subsurface circumstances because the range covers common coal measure geology.
Q5: For the longest possible service life, how should operators preserve these bits?
A: After every shift, routine cleaning avoids material accumulation, which lowers cutting efficiency. Before deploying, check PDC cutters for damage. To avoid impact damage, keep parts in protective cases. Choosing the right drill parameters stops excessive heat production, which weakens cutter bonding.
Q6: For continuous manufacturing, how much should operations stock?
A: Maintaining three to five bits per operating drill allows for sufficient rotation for cleaning and inspection based on common usage patterns. Drilling volume, formation features, and logistical concerns all affect your particular needs.
