Round Bar
Round bar is exactly as it sounds; a long, cylindrical metal bar. Round bar is available in a variety of metals including hot rolled or cold rolled steel, stainless steel, aluminum, alloy steel, brass and more; and in many different diameters ranging from 1/4″ up to 24".
Drill Rod
Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter. While typically round, drill rods may also be fabricated in square shapes. They are also often tempered prior to machining. This process involves heating the steel to relieve the hardness and to make the steel more workable. The steel is then air cooled before machining begins. Common applications of drill rods include drill bits, taps, dowel pins, shafts, and reamers. They are also used to manufacture hammers, files, and punches.
Shafting
Shafting, also known as 'Turned Ground and Polished' shafting, refers to round bars made with fine precision and high-quality steel. They are polished to ensure flawless and perfectly straight surfaces. The manufacturing process is designed for extremely close tolerances for surface finish, roundness, hardness, and straightness which ensures a long service life with reduced maintenance.
Shafting bars are commonly used often used in applications that require high accuracy, such as weather measuring devices, laboratory tools, high-speed motor shafts, drive shafts, pump shafts, and ball bushings. In these scenarios, the bar is often required to rotate at high speeds. Thus extreme straightness is critical to prevent unwanted vibration and wear on bearings.
