Henglong's core competitive advantage in retractable push button drill bits lies in its unique slotted retractable wing and extended tail structure. Compared with standard straight body button bits, the multi groove retract design delivers outstanding anti jamming performance. When stuck drilling accidents happen inside boreholes, operators can smoothly pull back the entire drill string without extra demolition work, drastically cutting project downtime and lowering safety risks in complex geological construction.

Our factory customizes each retractable rock bit to match on site drilling demands, with fully configurable connection threads, drill face profiles, and tungsten carbide insert styles.

Customizable Range

Thread Connection Types: R25, R28, SR28, R32, SR32, SR35, R38, T38, T45, T51, T60, GT60, ST58, ST68, T-WIZ60
Drilling Diameter Coverage: 33mm to 152mm, matching small drifting, medium tunneling, and large blast hole drilling requirements
Bit Face Styles: Flat drilling face, drop center concave face (for improved debris flushing)
Tungsten Carbide Button Categories: Ballistic carbide inserts, spherical round buttons, conical tapered carbide teeth, parabolic buttons

Core Product Advantages

1. Premium Raw Material Precision Heat Treatment

All drill bit blanks adopt high strength alloy forged steel, paired with wear resistant imported tungsten carbide buttons. Strict quenching and tempering processing avoids early cracking, carbide shedding, and rapid skirt abrasion under high frequency percussive drilling, extending service life significantly versus generic low cost bits.

2. Factory Direct Competitive Pricing

Bulk orders are eligible for wholesale discounts. Stable monthly output ensures consistent supply for long term mining and construction project partners, balancing top tier quality with budget friendly procurement costs.

3. Boosted On Site Drilling Efficiency

Optimized flushing hole layout accelerates rock cuttings removal, while angled gauge carbide teeth maintain straight boreholes. The anti stuck retract skirt minimizes stuck bit shutdowns, lifting overall daily drilling footage for quarries, coal mines, and infrastructure works.

Applications

Our retractable threaded button drill bits serve as core top hammer drilling tools for blast hole drilling, rock bolt drilling, tunnel drifting, and anchor hole construction. They are extensively deployed across open pit quarries, underground coal mines, highway slope stabilization, dam foundation excavation, urban tunnel engineering, and all similar hard / soft fractured rock construction projects worldwide.
