However, generally these compressors shouldn't have the power for deeper drilling, due to lack of space on the rig itself for the larger, more powerful units. Alternatively, agencies like Drilling Supply, are offeringcompressor 100 % free setup, which enables the driller to use a compressors with various power rated outputs to suit their particular project, while using the same RC Drilling Rig for these. As a consequence, even a broken air compressor will not cause disruption in the drilling treatments. While a malfunctioning compressor is being repaired, a backup unit can be rapidly deployed to continue the drilling operation, saving the drilling contractor energy and money.

RC drilling routinely achieves depths as high as 500 metres. This depth is much like that of Diamond Core drilling, but unlike core drilling, RC drilling does not produce a solid core. The cuttings generated by the RC drill bit are generally sent to the surface in the order in which they are produced but not constantly. Therefore, RC drilling is not since accurate as Core drilling. There is no way of knowing with a 100% certainty which depth the cuttings came from. Also there is a tendency with regard to heavier minerals (e. g. gold) to fall to your bottom of the hole or get caught in elbows and curves inside drill pipe (Reverse Circulation Look Pipe). As a result, assays from RC drilling may understate the quantity of mineralization present in the formation; however this deficiency is largely offset by significantly reduced cost with drilling and rapid penetration rates.

That is why, companies like Drilling Supply have developed amultipurpose hollow spindle rotary drive with variable/reversible hydraulic motor and automatic constant rotation power control. Drilling Supply is now able to offer drilling companies a capability to start the drilling operation with Reverse Circulation drilling just as soon as the mineralization warrants it and clean core samples need, switch to Diamond Core drilling technique. This is done by using the same drill rig and simply changing from RC drilling tool set to Center drilling tools (coring rods together with bit). This allows the driller to easily and inexpensively achieve the mineralization depth and commence extracting quality cores for analysis.

Drilling Ceramic Tiles - Ask the Expert

Stay away from Expensive Damage when Drilling Ceramic Tiles

We all like a certain amount of do-it-yourself, don't we? It's always better when you can do your home improvements yourself, without having to increase the cost by paying a specialized. However, it doesn't always turn out how you will expected, does it?

I've ended up called in, more than once, to 'pick up the pieces' by wives driven nearly mad by husbands with gone at the task of drilling ceramic tiles like a bull at a gate. The sight of a husband standing in front of an expensive ceramic tile installation - that they has damaged in repeated attempts to show that drilling ceramic tiles isn't beyond his capabilities - is not really a pretty one! • It is important you need when drilling ceramic tiles is the right tools for the job of drilling.
