Product Description

Product Details

Diamond Core Drilling Tools are very efficient as they only cut the circumference of the hole and not the mass of material.
There are some disadvantages: The drill being used must be capable of producing high torque at low speeds.
Core drills can bind with the dust especially if water is used - regular cleaning may be required during drilling.
The most important thing to recognise is the high chance of the bit causing a 'kick back' if it jams in the hole.
For this reason a drill with a handle or preferably a clutch mechanism is a good idea - especially if the drill is being used at height!

3.It is extremely effective in defining boundaries between ore bodies and waste rock

4.It is ideal for exploration, as it delivers contaminant-free samples, which are collected at the drill itself and can be sent immediately for assessment. It also reduces handling time, which in turn can serve to reduce overall program costs.
