Product Description

Product Description

 

Bench and production drilling tools are divided into R32, T38, T45, T51, T60, ST58, ST68 according to threads. Different threads according to different diameters of drill rods.
The products mainly include drill bit, drill rod, shank adapter and coupling.
 

Features of drill bit
Our drill bits are manufactured with high-strength steel alloys materials that ensures durability and wear resistance, even under the most challenging drilling conditions.
 

Properties of drill bit
42CrMo steel is a Chinese alloy steel, and has high strength and toughness, good hardenability, and no obvious temper brittleness. After quenching and tempering treatment, it has high fatigue limit and resistance to multiple impacts, and good low temperature impact toughness.
 

Application of drill bit
Our tapered drill bit is widely used in mining, drilling small aperture blasting in hole infrastructure construction. The mechanical properties of our drill bit are more excellent and has long service life which can continue to provide the strength and reliability of drilling required.
