Product details

KINGDRILLING offers a complete line of taper drill rods and DTH bits for all of your hand-held pneumatic drilling needs. Our tapered bit and rods come in a variety of taper angles.

KINGDRILLING Tapered Drill Rod is to provide 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 end. Tapered steel lengths are measured from the collar to the bit end. The drilled steel is extracted and followed with a slightly smaller diameter rock drill bit on the next steel length in the sequence.

Shank Hexagon: 22*108mm, 25*108 mm,  25*159 mm; 7, 11, 12 degree taper in most lengths, taper degrees of drill steel for excellent drilling productivity.
