   WIRE-LINE DRILL RODS  
   

Polmak manufactures high quality wire-line drill rods incorporating the latest production technology. For greater stability our wire line rods are flush joint and with outside diameters close to hole size , they reduce vibration. If the hole has to be reduced , wireline rods can be used as casing for the next smaller size.

 

HO, NO, BO and AO drill rods are within Polmak’s standard production and can be supplied from stock. For wear resistance, wire-line rods are chrome plated at our own premises.
