Tapered drill rods
Gimarpol’s Tapered Drill Rod with 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 drill bit in the end. Tapered steel lengths are measured from the collar to the bit end. Holes are usually drilled in 0.6 m increments to accommodate the air leg feed length. The drilled steel is extracted and followed with a slightly smaller diameter rock drill bit on the next steel length in the sequence.
There are two standard steel hex diameters – 22mm or 25mm. And Our tapered bit and rods come in a variety of taper angles( 7 degree, 11 degree, 12 degree)
