It made from high-grade steel and copper for superior durability and breaking strength.

Increased thickness enhances pressure resistance, ensuring robust performance under high loads.

Available in threaded or non-threaded designs to accommodate varying thread specifications.

Tapered drill rods are designed for use with small pneumatic or hydraulic rock drills in shallow-hole drilling applications. Typically manufactured from H22 and H25 hexagonal hollow drill steel, these rods must be paired with tapered drill bits for effective rock drilling. They are widely employed in quarrying, coal mining, road construction, and other field operations involving rock excavation. The standard taper angles for these rods are 7°, 11°, and 12°.

This demolition equipment is specifically designed for secondary block splitting and squaring. It serves as a highly efficient alternative to dynamite blasting or traditional manual splitting methods. Ideal for reinforced concrete demolition, it is widely used in various applications, including building demolition, bridge dismantling, and underwater structure removal.

Hydraulic Crimping Tool crimping power have 10 ton/12 ton /16 ton. The hydraulic crimper range can be suitable for 4-300mm² Cable Lugs. The head of our yqk hydraulic crimping tool can be rotated 180° freely to benefit narrow space working. with durable materials with high strength and good toughness futures, Difvan hydraulic crimping pliers provide a good choice for battery and welding cables, power wires, electrical cables, etc.

The low air pressure DTH drill bits used for 65-220mm diameter hole drilling，good performance in drill Granite, Marble, Limestone, Basalt, ect.It's mainly used in Blast holes, Quarry , Anchoring, Infrastructure, Geothermal holes.

Taper-button bits (used for small-hole rock drilling) differ from threaded-button bits (designed for long-hole drilling). Taper-button bits are paired with jackhammer rods for use in air-leg or handheld jackhammer drills, commonly employed in quarrying and mining operations

YN27C gasoline rock drills or petrol driven rock drill machine is powered by gasoline engine, without using air compressor, a very efficient machine with the characters that the structure is very compact, less of the-easy-to-damage-parts, and very easy to control. It can adapt to these outside situations there is no water and no electronic power. It is a kind hand held drill built up with gasoline engine, air pump, rock drill and the rotation plum bum equipment for running or stop. It can be used as a tool for breaking, percussive drilling, tamping besides rock.
