Generally, the light duty rock drill uses 7° Taper angle or smaller angle, the heavy duty rock drill mainly uses 12° Taper angle.
Advantages:
The tapered drill rod can be matched with multiple drill bits to drill blast holes with different diameters.
The tapered drill rod also has the advantages of no need of scrapping after abrasion of drill bits, simple maintenance, low price, low cost of drilling each meter, etc.
Description:
1. Shank Hex: 22m*/108mm, 25mm*108/159mm
2. Taper degree: 4.46 6 7 11 12
3. Drilling rod length: 0.4m-6m
Tapered steel rod work with taper drill bits which are usually hexagonal. When it comes to the small-hole drillingtools equipped with pneumatic & hydraulic rock drills, Taper drill equipments is prevailingly used for rock drilling, blasting holes and other drillingworks especially in the mining application and dimensional stone industry.
Taper steel rod are the same as integral drill rods which havedifferent length to fit different drilling applications in mining, quarrying, road building etc. Taper drill rods need tapered drill bits to work, such as tapered chisel bits, tapered cross bits and tapered button bits.
There are different taper angle ( 6 degree, 7 degree, 11 degree, 12 degree, etc. )on customers' request. Taper drill rods and taper drill bits must be in the same tapered degree.
