Advantanges: 

1. Reaming, stabilizing and maintaining the diameter of drilling hole. 
2. Large synthetic stones are used 

Tangshan Jinshi reaming shells feature increased stability and reduced vibrations due to the specially designed spiral pads, which provide increased contact with the circumference of the hole. 

Our reaming shells experience longer life in the field due to the greater number of diamonds and high-grade carbide reinforcements. Our diamond impregnated reamers feature large synthetic stones concentrated on the surface of the reamer pad. 

Size: 
Tangshan Jinshi reaming shells are available in all standard drilling sizes(BQ, NQ, PQ, HQ) as well as a number of region-specific sizes. 

Compatibility: 
Our diamond bits and reaming shells are designed to be compatible with all standard core barrels from other suppliers.
