Black Diamond Drill String Clamps
Black Diamond's Drill String Clamp is an essential tool to have on hand. It eliminates the need for welding of drill strings, which in turn reduces damage to top subs and shock subs.
They are manufactured from heat treated alloy steel to maximise grip strength and durability.
High strength fasteners provide the gripping pressure evenly along the length of the clamp. This prevents the drill tool joints from backing off.
Black Diamond Drill String Clamps feature a machine turned gripping pattern to provide maximum grip strength and minimal damage to drill rods.
