What are Boring Bars？
CNC machining often requires enlarging, finishing, or improving hole accuracy, and you'll definitely need boring bars. Simply put, a boring bar is a tool specifically designed for hole machining. It can make existing holes larger and smoother while maintaining dimensional accuracy. Unlike drill bits, which "drill" holes, boring bars "repair" holes. For example, if you need to machine a high-precision hole in steel, cast iron, or heavy metal, a boring bar can help you achieve tight tolerances and a superior surface finish. Different types of boring bars are suitable for different machining scenarios. You can choose the appropriate boring bar based on the material being machined, the hole depth, and the required accuracy.
If you're looking for higher machining efficiency and longer tool life, choosing the right boring bar will make your CNC machining more worry-free and efficient.

Usage and Installation
We recommend using cutting fluid to extend tool life and improve the machined surface finish.
Indexable inserts and clamping screws are small and easily lost.
Overtightening the insert screw may damage the screw or the wrench.
Tighten the clamping screw according to the following guidelines. Appropriate insert tightening torque.
How to Install an Insert with a Boring Shank
Initial Tightening
Start by holding the wrench as shown in the image. Begin rotating the wrench in a clockwise direction until it feels finger-tight. This means the bolt or fastener should not move freely, but you don't want to over-tighten at this point.
Ensuring Proper Torque
After achieving finger-tightness, hold the wrench securely and rotate it further. Aim for a rotation of approximately 60° to 90°. This extra rotation helps apply the proper torque, ensuring the fastener is securely tightened without the risk of loosening over time.
Why This Matters
Tightening too much initially can lead to excessive stress on the bolt or the material being fastened, while insufficient tightening can cause the joint to fail under pressure. The 60° to 90° final rotation strikes the perfect balance, ensuring long-lasting security and stability.
