How do I find a drill rod size & steel grade?

This Manufacturers Table shows the drill rod sizes and steel grades offered by the leading North American manufacturers. To use this table, find a steel grade in the left column. Read the sizes offered by each manufacturer in the other columns of the same row. An empty cell indicates that the manufacturer does not offer the product.

What type of steel is used for drill rods?

You can use many different tool steel grades to manufacture drill rods: W1, O1, A2, D2, S7, M2, and V44. Each of these grades has its distinctive features and properties that make it superior for a specific application. Depending on the type, some tool steels are stainless steel, while others are semi-stainless. What Is the Hardness of a Drill Rod?

What is the machinability of a drill rod?

According to the Rockwell measures, the same materials should be in the range between 96 and 110Rb. The machinability of a drill rod is closely related to the hardness. Different grades of tool steel have varying machinability power. Compared to 1.0% carbon steel, here’s the machining-friendliness of different grades of tool steel:

What are the different types of drill rod manufacturing?

In general, there are two main types of drill rod manufacturing: water-hardening and oil-hardening. To create a drill rod, the tool steel first gets heated until it becomes a glowing red color. Once it becomes red, it has to be cooled so that it hardens and retains its shape.

How to choose the right drill rods for hard rock drilling?

Choosing the right material for drill rods is crucial in hard rock drilling because it directly affects performance under challenging conditions. Steel is the most prevalent material used in drill rods due to its high tensile strength and durability, qualities that make it ideal for withstanding the stresses of hard rock drilling.

What is the best type of drill rod?
