Extension drill rod is a device that connects drill bit and is matched with rock drilling gadget to drill within the rock or soil.
Our corporation drill rods are manufactured from top rate, excessive-strength, alloy steel and are to be had in either hexagonal and round configurations. sandvik rods are evolved and designed to provide you straighter holes with much less deviation and longer provider life.
Frame kind
There are two shapes of extension rods, spherical kind and hexagonal kind.
Hexagon rods are more rigid, heavier and transfer strength more successfully, whilst increasing flushing.
Round rods are typically lighter than hexagonal rods and are generally used in extension drilling applications.
Thread type
There are specifically sorts of r-thread and t-thread.
R-thread specs are r25, r28, r32, r38, and many others. the primary dimensions and button profile of the r-thread mainly seek advice from the enterprise standard iso10208.
T-thread specs are t38, t45, t51, and so forth. the primary dimensions and button profile of t-thread mainly check with the corporate requirements which are almost the equal.
