Advantages of Kellyway core barrel
1---Core barrels are designed to operate on the principle of cutting by thrust indentation and shearing rotation, also called the “twisting and tearing” method resulting in a “rock crushing” mechanism depending on the rock strength and other rock characteristics.
2---The core barrel can be described as a cylindrical steel casing which is fitted with a series of single cone shaped roller bits at the bottom end to drill rock sockets for bored piles.
3---Each roller bit is fitted with a series of tungsten carbide insert buttons for drilling.
4---Kellyway Core Barrels with roller bits can crack rock with a width approximately equal to the diameter of the roller bit. Therefore, when the drill progresses, a rock core is created and it grows inside the cylindrical body.
5---However, if the diameter of the hole is large, the crack weakens the rock core but not enough to allow its breaking point and extraction.

Main Applications: gravel, boulder and medium mantle rock > >
Core Barrel with roller bits is used in very strong rock formations(compressive strength >100Mpa).
Core Barrels are used when conventional augers are less effective or in conjuction with tapered rock augers for very hard rock drilling. The Core Barrel is designed with cutting edge to maximise the penetration rate through less contact surface area having to be cut and removed.
