The RC bits are the tool cutting rock, referred to as “ Centre Sample Recovery” or “Dual Wall Drilling”, employs a Dual Wall pipe where the drilling medium, normally high pressure air, is the passed between the outer and inner tubes down to the face of the drilling bit where it is returned up the centre tube along with the sample cut by the drill bit.
Product parameters and features:
✔ Size: RE531 / RE004 / RE542 / RE543 / RE545 /RE547 / PR40 / PR52 / PR52R / PR54 / PR54R / RC45 / RC50. Bit Shank :RC/RE
✔ Applied to three different hardness rocks:soft, medium hard and hard rock.
✔ MIRACLE Reverse Circulation Drilling Products is becoming in creasingly popular around the globe, due to its high-quality sample results, and long-term, low-mainte nance endurance.
✔ These Reverse Circulation Drilling Tools devices must specifically be able to convey all cuttings up the center of the hammer and drill string so that they may be safely collected at the surface in the modern, environmentally conscious world.
✔ High-toughness carbide teeth are used, with a high wear-resistant formula (containing tantalum), so that the broken teeth rate is less than 0.2%;
✔ The trouser body is made of high-strength alloy steel, and after advanced heat treatment technology, the broken trouser body rate is less than 0.1%;
✔ Advanced CNC processing and advanced alloy tooth assembly technology are used to reduce the tooth loss rate to less than 0.1%.
Key Features
✔ Unique effect to complex and leakage formations maintains stability of the wall.
✔ High drilling efficiency due to strong capability of removing rock dust and flaks.
✔ Tested successfully that it can be applicated in more difficult conditions for more time.
✔ A variety of carbide designs and grades for use in different ground conditions.
✔ Single-piece sample tube assembly.
✔ Reverse Circulation Drilling DTH hammer ensures saving energy consumption.
