DNG hydraulic breaker chisels are reliable, robust, and durable. Fully compatible with breakers of various brands and help reduce costs .
Annually, our factory produces 400,000 chisel tools. These chisels tools are manufactured and processed using advanced mechanical techniques and technology, ensuring the finished products meet high-quality standards. The production process begins with the selection of premium alloys, which then undergo specialized heat treatment and final surface sandblasting. The result is a high-end product with exceptional hardness and wear resistance, demonstrating greater durability in demanding applications such as road construction, demolition, trenching, quarrying, tunneling, and mining.
Let DNG chisel tools help you increase productivity and reduce operating costs.
Three primary functions of DNG Chisel tools:
*Transmitting the “full” impact energy from the piston to the rock for higher efficiency.
* Offering high wear resistance to help control breaker operating costs.
* Protecting the main components of the hydraulic breaker from damage.
These functions allow DNG chisel tools to perform perfectly.
All chisel tools are manufactured to match the design, tolerances, and performance of various breaker brands. The uniquely designed impact surface of our chisels achieves impeccable flatness, allowing the piston to strike the entire surface of the chisel and transfer maximum energy to the rock. Conversely, if the impact surface is uneven, the piston strikes the chisel with very uneven energy distribution, which can cause serious damage to the piston itself, the lower hammer components, and the cylinder.
DNG chisels are made from special alloys of higher purity. High-purity alloys reduce weak points that can lead to cracks, minimizing the risk of chisel breakage. Also high purity allows for greater hardening of the outer shell without altering the material’s technical specifications.
DNG offers a comprehensive range of working chisel tools. Selecting the right tool for the right application helps achieve high productivity and lower operating costs.
Hardness Ratio Between Piston and Chisel Impact Surface: The ideal hardness ratio between the chisel’s impact surface and the piston is crucial. If this ratio is not optimal, either the piston or the chisel tool can easily suffer severe damage.
Selecting superior raw materials is the first step in guaranteeing the high quality of DNG chisels. This is followed by processing the materials with advanced mechanical techniques and sophisticated heat treatment processes, ensuring every chisel tool possesses identical characteristics.
This consistency allows us to predict the performance and durability of newly installed DNG chisel tools. Furthermore, customers can be assured that all DNG chisels passing our stringent quality control will deliver completely consistent product performance.
