CNC Milling 12 Degree Mining Rock Drill Tools Tapered Drill Rod
Description
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 0.6
mto 3.6 m in length—are measured from the collar to the bit end.
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 India, 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.
