Chisel

Chisel --- The chisels are used in the well and road engineering are to connect the drill bit and the rock drilling tool and hydraulic breaker or rock hammers.The chisel are generally used in the mine shaft and road engineering are hexagonal hollow steel and hollow round steel. The outer diameter of the round steel is 32mm and 38mm. The steel drill has a finished steel drill and a forged steel drill. The finished drill is forged according to a certain length and is directly installed with a drill bit. The forged steel drill is hollow according to need. Hexagonal steel is sheared, and then the forging head and head are forged with a forging machine, and then the drill bit is installed. Alloy steel drill head ---- The common drill head used in mine shaft engineering is a straight alloy steel drill head There are also cross-type alloy drills when drilling into hollow holes; Y-type alloy drills and X-type alloy drills, but the cost of the flat-shaped drill is lower, and the flat-shaped alloy drill is inlaid. The parent body is inlaid with a flat-shaped hard alloy, and the hard alloy can be reused after grinding.The size of the drill is generally 36mm --- 44mm.

Common chisel head shape

1: Conical quadrilateral type chisel

It is the most common type on the market. This shape of the chisel has a lot of penetrating power, even a very hard object can be easily separated by the force generated by its taper, including concrete without reinforcement or slightly reinforcement, high hardness rock, seam Rocks and so on. Its characteristics are: energy can be gathered at a point to produce a strong penetrating power, suitable for operations such as opening a mountain, repairing a road, demolishing a house, etc.

2: flat type chisel

That is to say, the chisel in the shape of a head is widely used. Flat rock drilling works the same as cone quadrilateral, but in the same working environment, the straight drill rods are more wear-resistant because their shape is more suitable for handling hard materials, all flat concrete rods are used to break the reinforced concrete. The effect is better. In addition, they are also suitable for excavation and trenching operations of sedimentary rocks, high-hardness and seamed rocks, and various soft and neutral layered rocks.

3: Flat head type chisel

Used in secondary crushing. Because it has no sharp ends like a tapered quadrangular drill rod and a flat-shaped drill rod, it is a blunt, so it cannot be broken by penetration and slashing operations. Its wear rate is only reflected in the length of use. The so-called secondary crushing refers to the crushing of medium-hard stones or broken small stones in order to further reduce them. Flat-head drills can also be used to break up brittle, hard objects such as metamorphic rock, sharp rock and slag. Its characteristics are: energy is released through the large surface of the flat head, does not produce torsion, and has a good crushing effect.
