Single Cone Rock Roller Drill Bits For Drilling Machines
KSQ Technologies (Beijing) Co. Ltd. can design all the rock reamer (Hole Opener) for bith horizontal directional drilling and vertical drilling as your special request,for example center shaft length,thread type,roller cones sizes,pilot size,extra projection on the plam,nozzles,nozzles sizes,for bith replaceable cones and fixed cones hole opener for your whole drilling project.We registered brand-Longyue.
Cuttong Structure: part of tricone bit,both steel tooth bits and tci bits are available
Products Application: bit cutter legs are mainly used in building big diameter piling bits or hole opener main type available
Most of regular sizes and IADC code
Available Sizes:from 2 7/8 to 26'' large sizes for hole opener bit,reaner bit
Application:petroleum&gas,water well,mining and tectonic industries,oilfield,construction,geothermal,directional bording,and underground foundation work hard formation rock /roller cone cutter bit uesd in hdd reamer
| Recommended Drilling Parameters | |||
| IADC | WOB(kn/mm) | RPM(r/min) | Formations |
| 117 | 0.30-0.75 | 180-60 | very soft formation with low compressive strenght and high drillability,such as caly,mudstone,chalk,etc. |
| 127 | 0.30-0.85 | 180-60 | soft formation with low compressive strength and high drillability,such as mudstone,gypsum,soft limestone,etc. |
| 217 | 0.35-0.95 | 150-60 | soft to medium hard formations with high compressive strength,such as medium soft shale,sandstone,limestone,etc. |
| 437 | 0.35-0.9 | 240-70 | soft formation with low compressive strenght and high drillability,such as caly,mudstone,chalk,soft limestone,etc. |
| 517 | 0.35-1.0 | 140-60 | medium soft formation with low compressive strength and high drillability,such as mudstone,sandstone,shale,etc. |
