ST58 Thread Reaming Rock Bit One Piece Heavy Duty Rock Reamer Bit
Tough projects demand tougher tools. If you’re tired of fragile drill bits failing on hard rock, mining, and tunneling sites, the ST58 Thread Reaming Rock Bit — One Piece Heavy Duty Rock Reamer Bit is your ultimate upgrade for heavy industrial drilling operations.
Crafted with a one piece integrated body design, this ST58 rock reamer abandons spliced and weak structures, delivering exceptional structural stability under high impact, high load drilling conditions. No more loose parts, no more breakage during intense reaming work, perfectly adapting to harsh underground mining, quarrying, tunneling, and construction drill and blast scenarios.
Built for heavy duty performance, the bit adopts high strength alloy steel with professional heat treatment technology, paired with premium tungsten carbide inserts. This premium build drastically enhances wear resistance, impact resistance and rock breaking efficiency. It effortlessly reams and enlarges pilot holes with smooth hole walls and precise bore diameter, solving the problems of uneven holes and low precision caused by ordinary drill bits.
The standardized ST58 threaded connection ensures tight, stable assembly with matching drill rods, realizing efficient power transmission and minimizing energy loss during drilling. Whether it’s deep hole reaming, hard rock excavation, or large diameter hole forming for casing and pipeline installation, this reamer bit maintains consistent, reliable performance for long term continuous operation.
