Conical Bit

Conical Bit or Cutter Pick

Conical Bit :

A miner bit has a base portion formed of two different metallic members welded together, one being adapted to be mounted to a continuous mining machine and the other having a frustoconical end portion welded to a frustoconical tungsten carbide bit.

Its called differently by different people and companies. Some call it Bits, Pick, Cutter pick etc.

The body of this conical bit is made of steel casting or forging having a conical nose end position provided with an axial hole in the front in which a tungsten carbide insert is mounted. The tungsten carbide insert extends from the front end of the nose portion of the metal body and provides the cutting surface of the bit. These conicals are mounted on Blocks which are also called Pick Box, Bit holder etc.. In use a large number of such bits are mounted for free axial rotation in the outer surface of a rotary drum, or in the outer surface of a continuous chain or the like, and the bits are moved through an orbit which is intercepted by the face of the material being mined .

The conical Bit also has a groove in the bottom side in which a retainer is attached for the conical to remain fitted into the bit block.

LNM has been making these conical bits for last 8 years having a capacity to make almost 1.5 million of them a year. Usually we make them out of different alloy steel hot or cold forged and then machined and heat treated.
