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.

Things have finally started to pick up around here after a very slow We are building three Manportable hydraocre, two Hydracore s, and one Gopher top drive. These Hydracore s will be the first 22000 machines we have sold with our new Hydracore Link Chuck.

We have sold two heads with this new chuck now, but these will be the first complete machines that will come hgdracore them. The new chuck finally removes the only weak spot on the Hydracore I guess this new chuck is pretty unimpressive looking on the outside.

It looks a lot like a normal auto chuck. This chuck is deceptively strong though. Not only is this new chuck strong, but it is also simple and durable. Drillers like using it. Eventually I think a lot more chucks are going to be made this way.

That is pretty good, but I have seen our Link Chuck holding 33, lbs. So far we have not had the equipment to test it at any higher forces than this. That is the maximum safe pullback on our Hydracore feedframe.


It may be that the Link Chuck is actually stronger hhydracore the Nitro Chuck!

Once hydeacore have more experience with this new chuck we will know for sure. It is certainly a lot simpler. If you look at the drill bit size chart you will also find a drill rod size chart.

Both of these charts have some extra information on them that you cannot get anywhere else. What I have is some constants that you can use to estimate the torque required to turn different sized bits and rods. No one pays much attention to what the maximum amount of torque a drill rod string can take is.

Many drills are capable of producing enough torque to break off a string of rods in first gear easily. Most drillers barely pay any attention to any numbers at all except maybe the number on their paycheque.

At Boisvenu Drilling the use of first gear on the Boyles 56 drills was banned because it was really too strong, if it was ever used it normally ended up in broken rods. Most drills have a really low first gear mainly because the transmission is really designed for use in a truck. 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.


Usually drillers discover this limit by breaking off a rod string. 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. The low speed mode is really equivalent to 2nd gear on other similar sized drills.

This sometimes makes our machines seem to appear inadequate on paper. In practice this lack of torque does not end up being detrimental at all.

It prevents broken rods. The Hydracore actually has more torque available than an LF 70 at all normal drilling speeds.

The LF 70 has an impressive ft-lbs. It is enough torque to easily wreck anything less than P size.

The torques and speeds available from the Hydracore drill head are just what is needed for safe high production. I think that our machines are in many ways a more logical solution to drilling problems that most other machines available. Many of our customers have found this out by running these machines. Hydracore machines work really well!

There is a lot more to them than you can see.

This month I have added a few links on our site to other companies who are our authorized distributors.
