    Description

    Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Different taper sizes have different characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning.

    • Suitable for small hole range
    • Widely used in Dimensional Stone Quarrying Industry
    • Widely used in Underground Mining Industry


    Color: Based on Customer requirements


    Material: Tungsten carbide and high strength alloy steel


    Processing: CNC milling and proprietary heat treatment process


    Type: 7° Tapered Hex 22 Tapered Rod Shank 22 mm x 159 mm


    Applications
    • Underground Mining
    • Tunneling

    Why There are many different Taper?

    Different taper angles are used for different rock formations and rock drills. A wide taper angle is normally used when drilling with high impact hydraulic rock drills in medium hard to hard and abrasive rock formations. Taper angles of 11°and 12° are common on modern rigs.

    A narrow taper angle of 7°is used for low impact rock drills and softer rock formations. This angle can also be used if you have spinning problems when using 11° or 12° equipment.

    In addition, a 4°46' angle is ideal for soft rock when you’re using pneumatic or hydraulic drill rigs – to prevent bits from spinning or becoming detached.
