PDC Three-Wing Scraper Grout Hole Coreless Drill Bits that differ from others
The PDC Three-Wing Scraper Grout Hole Coreless Drill Bit is an advanced drilling tool specifically designed for geological engineering, mining, and water conservancy projects. It innovates upon traditional drill bits with several significant features that distinguish it from others.
1. What Makes It Different
No Core Design:
Regular core drill bits take out rock samples. This is for geology tests. This drill bit breaks rock directly. This makes drilling faster.
No core means more room for debris. This stops the drill bit from getting stuck.
Scraper Design:
The scraper clears out rock debris well. This makes cutting faster. It also helps with debris removal.
The scraper’s shape and angle help it drill faster.
Grout Holes:
This drill bit has grout holes inside. This lets you grout while drilling.
This means you can drill and grout at the same time. This speeds up work and improves quality.
PDC Cutters and Three Wings:
PDC cutters are tough. They can break hard rock.
Three wings make the drill bit stable. This stops shaking and moving.
2. Where It's Used
Geological Engineering:
Finding ground information by drilling.
Making ground stronger by drilling grout holes.
Checking and fixing tunnels before they're dug.
Mining:
Drilling blast holes and grout holes in tunnels.
Drilling holes for blasting and grouting in mining.
Water Projects:
Stopping leaks and making dams stronger.
Checking and fixing tunnels when building water ways.
Building Construction:
Adding support to building foundations.
3. How to Use It
Pick the Right Drill:
Choose a drill that fits the situation where the hole is of a certain depth, size, and in a specific ground type.
Put the Drill Set Together:
Connect the drill bit to drill pipes and other tools.
Control Drilling Settings:
Set the right pressure, speed, and fluid flow for the ground and drill.
Do the Grouting:
Pump grout through the drill bit's holes while drilling.
Control the grout pressure and flow.
Check the Hole Quality:
Watch that the hole is straight and of the right size
Watch all of the drill's readings, and stop drilling if something is wrong, and check the drill and drill bit.
