Milled chisels with steel weapons.

Despite the fact that using carbide chisels, it is possible to drill almost any rock - from soft to strong, milled chisels continue to enjoy enviable popularity, which is possible due to some features:

• High drilling speed in medium soft and soft rocks;
• An important feature is the relatively low price compared to other types of bits.

Steel Chisel Features

One of the main tasks that the manufacturer needs to solve in the manufacture of such equipment is its durability, strength, reliability and wear resistance. This is possible due to the use of modern surfacing materials, as well as unique surfacing schemes.

The periphery and inverse cones of milled cones with carbide tines are also reinforced - this is how the new weapons concept is implemented. Instead of partial cladding of the runaway / runaway tooth faces, complete cladding is performed on all faces, as well as the blunting of the teeth with a rather hard and thick layer.

Steel chisels make it possible to significantly increase the speed of drilling. The cone consists of milled weapons, which are made in the form of longitudinal prismatic teeth to the bottom there are interventional grooves. The tops of the jumpers are located at a distance of 30-55% from the bottom of the grooves to the height of the prismatic teeth located on the middle part, and the type of cross-section of the jumpers in the plane of symmetry of the grooves has an acute angle with sides, both straight and curved. This solution allows you to increase the strength of the teeth, preventing fatigue cracking and breakage of the tooth.

Advantages of a steel chisel:

• High penetration rate;
• Excellent wear resistance
• Reliable and durable material of manufacture, allowing to extend the drilling time;
• Tungsten carbide surfaces.
