The High - Endurance 92 / 98mm Impregnated Diamond Core Drill Bit ; Effective Length : 18.8
In the fields of mineral exploration and geotechnical drilling, performance is primarily measured by two key indicators: penetration rate and bit life. When encountering hard and highly abrasive formations, the selection of equipment directly determines your drilling cost per meter.
1. Precision Engineering
92mm ID / 98mm OD
The 92 / 98mm configuration is specifically designed for high-standard core recovery.
Inner Diameter (92mm) : Ensures a substantial core sample size, providing geologists with ample material for accurate analysis and assaying.
Outer Diameter (98mm) : Optimized to maintain borehole stability while minimizing friction against the hole wall.
2. The 18.8mm Edge : Why Effective Length Matters
Most standard impregnated bits offer a matrix height of 9mm to 12mm. Our 18.8mm effective length provides a significant competitive advantage :
Extended Down - Hole Time : With nearly double the diamond - bearing matrix of standard bits, you can drill significantly more meters before needing a change - out.
Reduced "Tripping" Costs : Every time you pull the rod string to change a bit, you lose time and money. The 18.8mm crown keeps the drill turning longer, especially in deep-hole applications.
3. Advanced Matrix Technology
Our impregnated drill bits prioritize not only depth but, above all, quality.
Self - Sharpening Capability : The metal bond matrix features a custom - engineered design that wears down uniformly and at a controlled rate, ensuring that fresh diamond cutting edges remain constantly exposed and ready for action.
Broad Applicability : This drill bit is the ideal choice for drilling through formations ranging from medium-hard to ultra-hard. Whether you are encountering granite, quartzite, or basalt, this 92 / 98mm bit will help you retrieve smooth, clean core samples.
4. Applications
This specific size and length are the "workhorses" for :
Mineral Exploration : High - recovery gold, copper, and iron ore sampling.
Geotechnical Surveying : Large - diameter sampling for dam foundations and bridge pylons.
Environmental Drilling : Clean core recovery in deep bedrock.
Conclusion
Investing in a bit with an 18.8mm effective length is an investment in your project’s productivity. By reducing bit changes and increasing the lifespan of your consumables, you directly improve your ROI on every job site.
