Rock drilling tools factory ProDrill:
COD280-Concentric overburden drilling System by DTH Hammer which designed to drill and case a hole simultaneously through unstable ground conditions.
The driver bit incorporated with a one-time used ring or reusable ring makes a full face head design which significantly improves the penetration rate and hole straightness of drilling. The internal flushing grooves together with the built-in casing shoes gives a good seal to the button of the drilling hole, and thus mini missing the disruption of the surrounding of the drill hole.
- Code No. : COD280
Casing O.D.: 406mm
Casing I.D . :382mm
Ring Bit O.D. : 440mm
Casing Shoe I.D.: 364mm
Pilot Bit O.D. : 140mm
DTH Hammer : 12"
DTH Pipe :140mm
Application Range: suitable for drilling water wells, geothermal wells, short mircopiles, medium mini-type grouting hole of building, dam and harbor project.
1. Ring bit and casing shoe assembly is welded to casing prior to drilling. Lock the assembly into pilot bit with hammer. The pilot bit's upper shoulder engages the shoulder of the casing shoe.
2. Hammer's percussive energy is transferred through the pilot and ring bits, crushing rock . Part of impact energy advances casing.
3. On completion of drilling and casing , the drill string with pilot bit is retrieved by a slight reverse rotation to unlock the bayonet coupling . The ring bit stays in the hole , and can be recovered only if the casing is retrieved
4. Drilling continues to the desired depth in the bedrock using a conventional drilling.
Rock Drill Bits Advantages:
1.Full face head design for faster penetration and straighter hole less torque is required
2.Can drill in vertical, horizontal or any direction
3.Minimize disruption to the drilled hole
4.Varied ring bit diameters to suit different casing requireme
