4.5 Inch Shank SRC542 RC Drill Bit Black Color Carbon Steel For Sampling
Product Introduce:
RC drill cuttings are transported to surface inside the centre tube of the dual pipe. Because of this sample recovery is usually very good with high recoveries of both fines and clays.RC drilling today produces samples of high quality and reliability. Dual-pipe RC drilling utilizes double drill rods where air is passed down the hole through the outside annulus and into the hammer. Drill cuttings are cleared from the bit by the air and travel up through the centre tube of the drill rods remaining free from contamination.
Adavantages:
Achieves greater penetration in hard rock than air core drilling, thanks to the percussive force and the strength of the drill bit.
Provides greater sample accuracy, and cuttings are easy to catalogue. The collected samples have an exact location and depth where they were acquired, making it easier to more precisely locate mineral deposits.
Woring Principle:
By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination.

About us:
SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
Delivery Way:
By Air, By express or By Sea
Package :
Ply-wooden cases + pallet
