PENTAGON High Precision Boring Head Set Model: NBH2084 BT40
The NBH2084 Micro Boring Head Set is a high-precision tool designed for fine boring applications in
CNC milling machines. It offers exceptional accuracy and versatility, making it suitable for a wide range of
industrial machining tasks.
Features
High Precision: Achieves fine adjustments with a dial precision of 0.01 mm, ensuring accurate boring operations
Versatility: Suitable for a wide range of boring tasks, including internal, stepped, and face boring
Durability: Constructed from high-strength steel with a hardness of HRC 44–48, offering long-lasting performance
Ease of Use: Designed for easy setup and adjustment, enhancing productivity in machining operations
Very Wide Boring Range
Covers a much larger diameter range (8 mm to 280 mm), making it highly versatile for different hole sizes.
High Precision
Micro-adjustment feature with 0.001 mm accuracy helps you fine-tune the boring diameter with very high precision.
Strong & Stable Design
The boring bars are designed for good shock resistance and rigidity, which helps reduce vibration and improve surface finish.
The base design (occlusal surface) is “staggered” to ensure stable force distribution during cutting.
Flexible Tool-Holder Compatibility
While you’re asking about the BT40 version, the NBH2084 system is also available in
other holders (NT, MTA, R8, etc.) — which adds flexibility depending on your machine.
This makes it usable across different CNC machines or setups that use different taper standards.
Good Tool Kit Package
Comes with several boring bars (for different diameters), multiple wrenches for fine adjustment, and a handle.
The set is designed for “micro-boring” but can also handle a variety of bore sizes with its modular bars.
Applications
Precision Boring: Ideal for applications requiring high-precision internal diameters
