    Impact Drill Bit for Rock Layers with High Penetration Rate

    A brief introduction to impact drill bits:
    Selection of drill surface shape:
    1. Downward center position
    Used for high permeability in soft to medium hard and fractured rock formations. Low to moderate air pressure. Maximum hole deviation control.
    2. Concave surface
    Specially designed for all-round application of drill bit surfaces in medium hard and homogeneous rock formations.
    Good hole deviation control and good flushing ability.
    3. Convex surface
    For high penetration rates ranging from soft to medium hard at low to moderate air pressure. It is the most resistant to steel washing, which can reduce the load and wear of instrument buttons, but the hole deviation control is poor.
    4. Flat drill bit
    This surface shape is suitable for hard to very hard and abrasive rock formations in high-pressure applications. Good penetration rate, resistant to steel washing.

    Post job maintenance: extend the next service life
    Thoroughly clean: Use a wire brush to remove debris and mud from the surface of the drill bit, especially to clean the residual slag blocks in the chip groove; If in contact with seawater or corrosive liquids, rinse with clean water and wipe dry.
    Inspection and repair: Drill bits with slight chipping can be polished with an angle grinder to maintain the original angle and extend their usage; When loose alloy teeth or cracked welds are found, they should be immediately scrapped and cannot be continued to be used (to avoid injury caused by falling teeth during operation).
    Proper storage: After drying, apply anti rust oil on the surface of the steel body (especially at the threads and welds), put it in a drying toolbox, and avoid collision with other hard objects (especially protecting the alloy teeth and cutting edges).
    Summary of Core Principles
    The use of impact drill bits should follow the eight character formula of "adaptation, cooling, stabilization, and cleaning": select the right drill bit model, ensure cooling and lubrication, control force and angle, and promptly handle abnormal situations. Doing these things well can not only improve work efficiency, but also extend the life of the drill bit by 2-3 times, while reducing safety risks.
