Plug samples, usually 1 inch and 1.5 inch in diameter are taken from core samples for testing. These require to be perfect cylinders. It is extremely essential that the drill press or its shaft does not vibrate during the plugging process.
A recirculating fluid tank can be provided with the drill press to minimize the use of fluids during plugging and reduce pollution
Swivel assemblies are available to plug under fluids and under liquid nitrogen.
- A 3 phase 2 hp motor is capable of drilling into any rock from soft limestone to hard granites.
- The bed can be rotated to take plugs in any angle desired, example parallel to bedding planes
- Speed can be reduced so that samples can be taken in soft rock, for example while plugging under liquid nitrogen.
