Good quality Button Drill Bits for sales
Good quality Button Drill Bits for sales
The top hammer series are available to Atlas and Sandivik,I have been their agent before,but their price is too high,the cooperation with Prodrill brings me new business and gives me more profit space,I believe in it and recommended Prodrill to you.

—— Switzerland

I am confidence the quality is similar to Robit and Rocksmith and with our designs having better carbide patterns and sizes I think we should do well.

Coupling Sleeve full-bridge R25/R32/T38/T45/T51;Semi-bridge/Full-bridge


The coupling sleeve is an indispensable accessory in the drilling tool. The coupling sleeve is in the joint part of the supporting drill during the drilling process, and is subjected to the corrosive action of axial tensile, bending and torsion, contact, friction and the like. Therefore, it is very important to properly select the steel for the connecting sleeve and optimize its geometry and manufacturing process. The connecting sleeve is connected with two or more drill rods or tail drill rods on the same axis by its thread, and transmits the impact function of the rock drill to achieve the purpose of drilling the rock hole, and acts as a stress wave propagation carrier as the drill rod. .


Semi-bridge coupling, by far is the most popular, has a small non-threaded bridge in the centre. The drill rod cannot thread past the centre of the couplings, and the smaller diameter rods portions butt together in the centre bridge area of the coupling. Semi-bridge couplings are most suited to high torque machines. Most rope (R) and Trapezoidal (T) threaded couplings are semi-bridged.


Full bridge coupling has a great advantage that it positively eliminates the potential for the coupling to creep along the threaded joints. These couplings, are typically used in a Trapezoidal thread, in surface drilling application, have better uncoupling characteristics and tend to maintain tighter joints. Full-bridge couplings have less chance of jamming and are best suited to machines equipped with independent rotation.
