FAQs
1. What parameters should I verify for a 28mm coal mining PDC anchor drill bit?
Check diameter accuracy (28±0.2mm), blade count (4-6), and connection type. For mining-specific requirements, recognized coal mining tool manufacturer SHAANXI HAINAISEN uses ISO-certified quality control.2. Are PDC anchor pieces robust in difficult coal seams?
High-quality carbides and heat-treated bodies avoid wear. SHAANXI HAINAISEN, a leading PDC anchor drill bit manufacturer, employs ultra-hard tungsten carbide tested for 300+ hours in abrasive settings for demanding coal layers.3. What carbide grade offers durability?
Hardness and impact resistance are balanced in Grade YG15 (94% tungsten). SHAANXI HAINAISEN customizes carbide mixes to meet rock hardness, lowering bit replacement by 40% in field trials.4. Does this portion work in mixed sandstone-coal formations?
Yes! Their diamond-enhanced cutters handle 120 MPa rocks. Many coal mining tool providers lack this adaptability, while SHAANXI HAINAISEN builds bits for various geology with 15+ years of OEM experience.5. Can I request special bit designs for particular setups?
Absolutely. Blade geometry, flushing port, and material changes are available from reliable coal mining drill manufacturers like SHAANXI HAINAISEN. Share your needs, and their engineers will optimize solutions. Ready to upgrade? Contact [email@hainaisen.com] for a quote!
