Applications
1.Kelly bars are key components in the execution of boreholes with hydraulic rotary drilling rigs. They transfer the torque of the rotary drive and the crowd pressure of the crowd system concurrently to the drilling tool. 

2.A Kelly bar consists of 2 – 5 telescopic tubular sections with a system of drive keys and lock recesses, welded onto their outer surfaces.

3.Standard Kelly bars are fabricated with a total of 6 drive keys on each section. The tubular Kelly sections are manufactured from high-tensile steel to ensure minimum weight at adequate strength.

FAQ
Q:What is a Friction kelly bar
A: A friction kelly bar is a tool used with an auger to drill through clay, silt, and loose sand or gravel. This tool transfers crowd force and torque from the rotary drive tool to the drilling tool or auger. In other words, a friction kelly bar provides an extension to the auger to increase the depth of a borehole.
Q:Do you provide drawing of friction kelly bar or interlocking kelly bar before production?
A:Yes,all drawing will be sent before production.
Q:Can I treat Hyper Drill for drilling tools as our first choice?
A: With more than one decade's experience in the pile driving industry, Hyper Drill is your first choice for all your piling needs.
Q:Are Kelly bar used for more than drilling?
A:These two kelly bars can perform another task on the construction site besides drilling boreholes. You can install utility anchors to support and stabilize a foundation with a kelly bar adapter. However, you must ensure the kelly bar adapter is compatible with the type of Kelly bar you attach to this tool.The bottom line is to use a friction kelly bar if you're drilling through clay or silt and an interlocking kelly bar if you're drilling through loose rock for maximum torque.
Q:Any related additional service?
A: To get the ideal performance, our technical team will offer support from the kelly bar customized design to the operation data & suggestions.
