drilling auger with tungsten carbide bits
1.-- UNIMATE rock drilling augers are mainly divided into two types:
1- Conical Rock Auger
2- Flat or Butterfly Rock Auger
1) Conical Rock Auger ( Single cut auger and Double cut auger)
Drilling Diameter Range: 600~1800mm
Main Applications:
1- Single Cut Augers and Double Cut Augers are suitable for drilling in medium to strong rock (15~60MPa)
2- Double Cut Augers are recommended for bigger diameters uncased boreholes.
Features:
1- Sturdy and wearable rock pilot for accurate positioning
2- Hard facing strips for wear protection and service life extending
3- Kelly box size as per customer demand
2) Flight or Butterfly Rock Auger: (Single-Cut Auger, Double Cut Auger, Double Cut Auger without Rock Pilot)
Drilling Diameter Range: 600~1800mm
Main Applications:
1- Flat or Butterfly Rock Augers are suitable for drilling in weak fractured rock and very dense sand and gravel (Less than 5 MPa)
2- Double Cut Augers are mainly used for bigger diameter uncased boreholes and secant piles.
3- Double Cut Auger without rock pilot are recommended for fractured rock or moderately weak to moderately strong rock (5~50 MPa)
Features:
1- Sturdy and wearable rock pilot for accurate positioning
2- Hard facing strips for wear protection and service life extending
3- Kelly box size as per customer demand
