The Hydracore is one of the most versatile machines for core drilling. It is ideal for drilling N size holes to about feet, but it can also drill H size to . Hydracore News. Stay up to date with the latest Hydracore News. . We are building three Manportable drills, two Hydracore s, and one Gopher top drive. The Hydracore is a light weight (lb/pick) diamond drill that can be used in skid mount and heliportable operations. This rig is designed for modular.

We have built a hydradore Manportable drills this year. The assumption is that the force on the bit would be in proportion to the area of the bit in that way the torque to turn the bit would be effected by the bit area, and the diameter of the bit.

Later it was hydracoe to a surface machine by lengthening the stroke and installing a Diesel engine in place of the electric motor. The Hydracore Gopher was the original manportable drill. The diameter used to calculate the torque constant is the diameter mid-way between the outside, and inside of the kerf of the bit. The Hydracore has the same P 0200 head as the Hydracorebut the feed frame is larger.

Drill Rod and Bit Charts These charts have information that you cannot find anywhere else, about drill bit sizes, drill rod sizes, and constants that can be used to figure out drill bit and drill rod torque. Sometimes we build stuff that is not for drilling at all.

The low speed mode is really equivalent hydracorre 2nd gear on other similar sized drills. Drillers like using it. This month I have added a few links on our site to other companies who are our authorized distributors. The first chuck we made has now been in steady use since September We have had a very busy year here at Hydracore.


More torque is available in reverse for rod breaking, because the reverse pressure is set at the intermittent pressure of the system of 5, psi and the maximum pressure in forward is only 3, psi. That is pretty good, but I have seen our Link Chuck holding 33, lbs.

It has a P size head that makes it possible to drill P size or advance a lot of H size casing.

If you are reading this then you will have noticed that we have a new web site. We want to make our image match our abilities. This month we 20000 not very busy so we are building a machine for stock. So far this year, we have built 23 machines.

What I have is some constants that you can use hydtacore estimate the torque required to turn different sized bits and rods. In February we built a special rod puller for AMC mining.

Both of these charts have some extra information on them that you cannot get anywhere else. Eventually I think a lot more chucks are going to be made this way. Then I went to Chile to see Expert Drilling. BC Hydro used it to drill anchor bolt holes for transmission […] More. It is ideal for drilling N size holes to about feet, but it can also drill H size to feet or B size to feet.

Usually drillers discover this limit by breaking off a rod string.


Many of our customers have found this out by running these machines. I think they have the windiest roads in the world. The Hydracore Underground uses many of the same components as the Hydracore surface drill. One difficulty was that this machine will […] More.

It is certainly a lot simpler. It is designed to be quickly broken down into loads no heavier than lbs. The older mechanical drills often had some really low gear ratios, but some protection was given to the rod string because the engines would not produce much torque when they were almost at the point of stalling. I think that our machines are in many ways a more logical solution to drilling problems that most other machines available.


The LF 70 has an impressive ft-lbs. We are building three Manportable drills, two Hydracore s, and one Gopher top drive.

Hydracore – Hydracore Drills

In practice this lack of torque does not end up being detrimental at all. We are building three Manportable drills, two Hydracore s, and one Gopher top drive. It has been just over a year since I bought the company along with my partners Larry and Travis Donaldson.

The special components for the underground version are the feed frame, and the feed frame positioner. Most drillers barely pay any attention to hydfacore numbers at all except maybe the number on their paycheque.

News – Hydracore Drills

Often the drag from the drill hjdracore can be cut in half just by greasing the rods, but this chart may perhaps give an idea of the amount of drag from different hydrracore sizes. The Hydracore is the most powerful drill Hydracore makes. The chart shows that it will take about half as much torque to turn an A size rod string as a B sized one.

It may be that the Link Chuck is actually stronger than the Hydracoore Chuck! On the specification sheet for a Hydracore the torque in low speed mode is not as high as with some other drills like a Longyear LF 70 for example. Some customers have drilled feet of N in very inaccessible sites with these machines.

The new chuck finally removes the only weak spot on the Hydracore It prevents broken rods. It can be made with a gasoline or diesel engine of 30 or 40 HP, and is capable of feet B or feet of N.
