Taper drill rod is used for rock drilling, blasting holes and other drilling works in the quarries, coal mines, traffic and other contractions. It works with taper drill bits and has different length for various applications, our taper drill rods come in a variety of taper angles, generally, the light duty rock drill usually use 7 taper or smaller taper angle, the heavy duty rock drill mainly use 11f=12 taper angle. And the basic theory is that taper drill rods and taper drill bits must be in the same tapered degree. We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs. 1,1+Steel grade: 55SiMnMo++40SiMnCrNiMo, 95CrMo equivalent to SANDBAR 20 or C253, 2,Shank size: hex.22mmf-108mm , hex.22mmf-159mm, hex.22mmf-80mmhex.25mmf-108mm. hex. 3,Taper:6fp++7fp++11fp++12fp++etc 4,Length:0.5m-9m 5,Package: in wooden case or in bundles. 6,Supply ability:3000MT/month 7,Delivery time :30days 8,Payment terms:T/T or L/C.
Our tapered drill bit is from alloy steel and tungsten carbides by forging treatment. it can connect with tapered drill rod well for air leg or hand-held rock drill machines for drilling holes in gold and coal mining, marble and granite quarries, stone project, tunnel, water conservancy, etc.Applicable Industries: Applicable Industries: Construction works , Energy & Mining, drifting, tunneling Weight (KG): 0.3 Type: DRILL BIT Machine Type:Drilling Tool Material: High Manganese Steel, Tungsten Carbide Processing Type:Forging Use:Ore Mining Color:customized Usage:Drilling and Construction Application:Stone Drilling, Coal Mining,Quarry drilling, Construction Certification: ISO9001 Advantage: high quality ,High Performance button: 6-8 buttons Heat treatment: Fully carburization
