About Carbide Insert Boring Bar

Carbide Insert Boring Bar

Boring bars are used for INTERNAL MACHINING on CNC or manual lathes. A boring bar is used to increase the diameter or finish machine a pre-existing hole.

We have a full range of boring bars including: double clamp, steel shank, carbide shank, through coolant, lever lock and screw clamp for ALL ISO turning inserts.

The most popular boring bar is 95 degree SCLCR style tool which is screw clamping and available in steel or carbide shank.

For negative turning inserts, we always recommend using DOUBLE CLAMP boring bars instead of lever lock. Double clamps offer the most secure clamping, preventing insert lift and eliminating vibration. Double clamp turning tools can increase insert tool life by as much as 40% whilst improving surface finish. For deeper boring applications carbide shank boring bars can be used for boring up to 5 times diameter deep (5XD). Through coolant boring bars can increase insert tool life and help clear swarf better.

Advanced Compatibility for Versatile Machining

Designed to accept popular ISO standard carbide inserts such as CCMT, DCMT, and VCMT, this boring bar provides exceptional versatility for a variety of metalworking requirements. The ability to easily replace indexed inserts extends tool longevity, improving cost-efficiency for distributors, exporters, and machine shops alike.

Engineered for Durability and Performance

Boasting a surface polished and PVD-coated for superior anti-corrosion, along with a shank hardened to HRC 4555, the boring bar withstands heavy-duty industrial conditions. Its cutting edge is precisely ground to ensure minimal tolerance and maximize operational reliability, even in demanding environments.

High Accuracy and Flexible Operation

Delivering a cutting accuracy up to 0.01 mm, this boring bar integrates seamlessly with both manual and CNC lathes. It is available in multiple lengths and diameters, each balanced for vibration-free, high-speed operation and equipped with either external or through-tool coolant channels for optimal chip evacuation and cooling.

FAQs of Carbide Insert Boring Bar:

Q: How can I determine the correct carbide insert type for my boring bar?

A: Refer to your boring applications material and required geometry, then select an ISO standard carbide insert like CCMT, DCMT, or VCMT. These inserts are compatible with this boring bar and suit most precision metalworking tasks.

Q: What materials can this carbide insert boring bar effectively machine?

A: This tool is engineered for precision machining of steel, stainless steel, cast iron, and non-ferrous metals, making it suitable for a broad range of industrial and mold-making applications.

Q: When should I replace the carbide insert on my boring bar?

A: Replace the carbide insert once you observe signs of wear or decline in cutting performance. Indexed inserts are designed for quick replacement, extending the overall service life of the tool.

Q: Where is this tool best utilized in the machining process?

A: It is ideal for internal metal boring and finishing processes using manual lathes, CNC machines, or dedicated boring machinesespecially where a polished finish and high dimensional accuracy are required.

Q: What benefits does the TiN coating provide for this boring bar?

A: The Titanium Nitride (TiN) coating enhances the bars resistance to corrosion and wear, extends tool life, and supports operation under high temperatures (up to 900C, depending on the insert).

Q: How is coolant delivered during operation, and does it improve performance?

A: Coolant can be supplied externally or through the tool, depending on the model. Effective coolant delivery aids in chip evacuation, reduces heat generation, and improves tool longevity and workpiece finish.

Q: What are the main advantages of choosing a boring bar with a precision-ground, replaceable carbide insert?

A: This design ensures high cutting accuracy (0.01 mm), enables easy insert changes to maintain sharpness and productivity, and provides reliable, high-speed performance with consistent results.
