Shank Hexagon: 19 x108 mm, 22x 108mm, 25 x108 mm, 25 mmX159 mm 6, 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, likeour model no. PD-Y58 crawler hydraulic rock drill. Also for Y6, Y10, 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 6, 7, 11, 12 degreetaper, drill
hole diameter: 28mm-57mm.
