Drill Rods
Manufactured in house, Colcrete Eurodrill can to provide DTH Friction Welded Drill Tube and Rotary Drilling Friction Welded Drill Rods with A.P.I. connections.
Drill Pipe up to 139.7 mm (5 ½") diameter friction welded in house.
Drill Pipe is manufactured up to 406 mm (16") diameter and 9 metre effective length.
All tool joints are nitrided for extra wear resistance.
Standard drill rod lengths are 1000 mm; 1500 mm; 2000 mm; 3000 mm and 6000 mm.
Other sizes and special rods can be manufactured to suit your requirements.
DTH, Rotary, Blast Hole, RC ...
All standards undertaken.
Rods up to 140 mm dia. are normally friction welded. Above 140 mm are shrunk and welded.
Spanner Flat details to be agreed when ordering.
