    4,Very cost-effective

    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.
