Tapered rod
Taperdrill roday ginagamit para sa rock drilling, blasting hole at iba pang drilling works sa quarry, coal mine, traffic at iba pang contraction.Gumagana ito sa mga taper drill bit at may iba't ibang haba para sa iba't ibang mga aplikasyon, ang aming taperdrill rodAng mga ito ay may iba't ibang mga taper na anggulo, sa pangkalahatan, ang light duty rock drill ay karaniwang gumagamit ng 7 taper o mas maliit na taper angle, ang heavy duty rock drill ay pangunahing gumagamit ng 11,12 taper angle.At ang pangunahing teorya ay ang taper drill rods at taper drill bits ay dapat nasa parehong tapered degree.Nagbibigay kamitapered rods sa isang buong hanay ng mga shank configuration at steel hex diameters para sa hand-held pneumatic drilling na mga pangangailangan.
