Diamond cutting teeth

Diamond cutting picks are primarily used in tunneling through harder rock strata, mining coal seams containing coal gangue, road milling, engineering rotary drilling rigs, and dual-cutter equipment. When cutting coal and rock faces, these cutting picks endure high cyclic compressive stress, shear stress, and impact loads. Moreover, friction and impacts can cause the temperature of the cutting picks to rise. Under such complex operating conditions, the cutting pick teeth must not only exhibit excellent wear resistance and good impact toughness but also possess outstanding thermal stability. Compared with cemented carbides, diamonds offer superior wear resistance, longer service life, and greater cost-effectiveness.

  • Product Description

  • 　　Cutting picks are critical components in tunneling and also one of the major consumable parts. The composite cutting picks from Wuhan Rite Diamond boast excellent properties, including high wear resistance, strong impact resistance, and a high thermal conductivity. The cutter body has undergone special design and processing techniques.

    　　For different geological conditions, Wuhan Rite employs composite teeth with varying performance requirements to optimize application outcomes. Compared to conventional cemented carbide cutters, diamond-tipped cutters offer advantages such as increased penetration rate, higher drilling efficiency, and lower operating costs.

    　　Technical Features

    　　The shank is made of a special steel alloy—molybdenum-nickel alloy—characterized by high strength, excellent hardenability, high toughness, minimal distortion upon quenching, and superior high-temperature creep and strength performance. The steel body undergoes a specialized heat treatment that imparts a high fatigue limit and outstanding impact resistance, as well as excellent low-temperature impact toughness.

    　　The tooth tips are made of diamond-composite teeth, produced using a high-temperature, high-pressure synthesis process. They exhibit extremely high wear resistance, excellent impact resistance, and superior thermal stability. Additionally, they possess a range of outstanding properties, including rapid thermal conductivity and corrosion resistance.

    　　The tooth head and the tooth shank are joined using a cold-setting process.

    　　Compared to carbide cutting picks, diamond cutting picks have the following advantages:

    　　Long service life

    　　Reduced the frequency of cutter bit replacements.

    　　Reduced the cost of using cutting picks.

    　　Improve mining/excavation efficiency

    　　Increased equipment utilization.

    　　Improved operational reliability and reduced worker labor intensity.

    　　Diamond cutting picks have a long service life and place higher demands on the performance of tooth sleeves and tooth holders. We recommend that customers use our matching tooth sleeves and tooth holders to fully harness the excellent performance of diamond cutting picks.

    　　Coal Cutting Pick Series

    　　Coal cutting picks are critical components of coal mining machines, responsible for breaking rock and coal seams. They are also among the most vulnerable parts of such machines. The performance of coal cutting picks significantly affects coal mining productivity, power consumption of the mining machine, operational stability, workers’ labor intensity, and the service life of other machine parts. Compared to conventional alloy cutting picks, diamond cutting picks exhibit superior wear resistance, longer service life, higher construction efficiency, and better cost-effectiveness—particularly in mining coal seams containing hard rock, where their performance is especially impressive.

    　　Mining Cutter Bit Series

    　　Cutting picks for tunneling are among the most vulnerable components in tunneling operations and are used in conjunction with tunneling machines. The performance of these cutting picks significantly influences such factors as the efficiency of tunneling operations, the power consumption of the tunneling machine, operational stability, workers’ labor intensity, and the service life of other machine parts. Compared to conventional alloy cutting picks, diamond cutting picks exhibit superior wear resistance, better thermal stability, longer service life, higher construction efficiency, and a more favorable cost-performance ratio—particularly when working with hard, quartz-containing rock formations.
