DIAMOND REAMING SHELLS

SIZE
AX, NX, NXD3, AS, BS, NS, NS3, HS, PS, T Series

USAGE
Diamond Reaming shell is connected with a Bit to be used, and the drilling by Bit and grinding of side surface can be done simultaneously, but the drilled hole should be kept not smaller than the diameter of the Bit (Reaming).

It should be used to prevent early wear and tear of the outer diameter of the Bit, and also prevent vibration and deformation of the whole walls.

As shown in the figures, it has a cylindrical shape, with diamond particles attached at outside diameter and touchable screws at both ends.

Diamond Reaming Shells are produced with the outside diameter larger than that of the Bit.

FEATURES
There are 2 types of Taesung’s Diamond Reaming Shells, one is for general rocks and the other is screw type for strong rocks.
Taesung’s Diamond Reaming Shells have excellent life span and reaming ability as high quality shank and natural Diamond are used in producing it.

USAGE

1. Drill Rods

It is drilling equipment with Core Barrel and Bit attached at its foremost part and is maintained by the Chuck of the Drill Rig.
It’s main role is conveying the rotation and pressure generated by the drilling machine and making the drilling
water reach to the Bit, and also conveying the rapid cooling or slime.
