Anti Rust Tapered Threaded Rod Carbon Steel Integral Hexagonal Drill Rods

Jincheng Integral Tapered Drill Rods

Tapered drill rod,another name called taper rod, tapered drill steels, This provides a hexagonal chuck section to provide leverage for the rotation chuck bushing. It usually has a forged collar to maintain the proper shank striking face position in the rock drill, and a tapered bit end. Tapered steel lengths— available from 0.6m to 3.6 m in length—are measured from the collar to the bit end.

Characteristic

A wide taper degree is normally used when drilling with high impact hydraulic rock drills in medium hard to hard and abrasive rock formations.

Generally, the lightduty rock drill uses 7 taper or smaller taper degree, the heavyduty rock drill mainly uses 12 taper degree.

The tapered drill rods have a tough life, transferring the percussion energy from rock drill to drilling bit and then into the rock. They're also subjected to high bending stress, not to mention corrosive water in the flushing hole.

It is forbidden to keep working when the tapered drill rod is bended, otherwise the service life of the tapered drill rod would be decreased.
If the tapered drill rod was sheared, it can be restored by re-machining a new taper.

Specification

Shank Hexagon: 19 x108 mm, 22x 108mm, 25 x108 mm, 25 mmX159 mm 7, 11, 12 degree taper in most lengths, taper degree of drill steel is mostly imports for excellent drilling productivity.
For drilling medium-hard to hard and abrasive rock formations,Taper angles of 11 and 12 degrees are normally used on modern drill rigs, like YT28B, YT29A, Y24, YT24, Mobile rock drill pneumatic and hydraulic.
For low impact rock drills and softer rock formations, a narrow tape range of 7 degrees is used, such as Indian, Saudi's granite and marble quarry.
A comprehensive range of taper button bits, cross bits and chisel bits with 7, 11, 12 degree taper.
