When standard drills or rough boring tools cannot meet the strict dimensional tolerances and surface finish requirements of a critical hole, a precision fine boring head is essential. The NBH2084 Precision Boring Head is a highly versatile and accurate tool designed for finish boring operations. The internal lead screw mechanism is ground to exacting standards, allowing the operator to dial in micro-adjustments to the cutting diameter with absolute confidence. Packaged as a complete set with a BT40 shank, multiple boring bars, and indexable carbide inserts, this kit provides everything you need to start producing perfect bores immediately.
Micro-Precision Adjustment: The easy-to-read, laser-etched dial features a graduation of 0.01mm per division (on diameter). The internal mechanism is designed to eliminate backlash, ensuring that every adjustment translates exactly to the cutting edge.
Wide Boring Range: The NBH2084 head is designed to accept various sizes of boring bars. The complete set typically includes 8 pieces of boring bars of different lengths and diameters, allowing you to bore holes ranging from 8mm up to 280mm (with the appropriate extension slide).
High-Rigidity BT40 Shank: The MAS 403 BT40 shank is forged from premium 20CrMnTi alloy steel, case-hardened to HRC 56-58, and precision-ground to AT3 taper accuracy. This ensures maximum spindle contact, minimal runout, and the rigidity needed to prevent chatter during fine finishing cuts.
Modular Design: The boring head can be detached from the BT40 shank. This modularity allows you to use the same NBH2084 head on different machines by simply swapping the base shank (e.g., to an HSK63, CAT40, or SK40 shank).
Through-Coolant Capability (Optional): Many of our boring heads and bars are designed with internal coolant channels, directing high-pressure fluid straight to the cutting edge for superior chip evacuation and extended insert life in deep holes.
Direct Manufacturer Savings: Source your precision boring systems directly from our factory, bypassing trading companies for highly competitive wholesale pricing.
Complete Tooling Packages: We supply not only the boring head sets but also a full range of replacement parts, extension slides, and premium indexable carbide inserts optimized for steel, aluminum, or cast iron.
Strict Quality Control: Every NBH2084 boring head undergoes rigorous testing for dial accuracy, repeatability, and dynamic balance before shipment to ensure flawless performance out of the box.
Q1: What does the "0.01mm" accuracy mean?
A: The 0.01mm accuracy refers to the adjustment on the diameter of the hole. When you turn the dial by one single graduation mark, the boring bar moves radially by 0.005mm, which increases or decreases the total diameter of the bored hole by exactly 0.01mm.
Q2: Can I use this boring head for roughing operations?
A: The NBH2084 is a fine (precision) boring head designed for taking light finishing cuts (typically removing 0.1mm to 0.5mm of material) to achieve tight tolerances and smooth surface finishes. While it can handle light roughing, using it for heavy material removal can damage the delicate internal micro-adjustment mechanism. For heavy stock removal, you should use a dedicated twin-cutter rough boring head.
Q3: Are the boring bars proprietary, or can I use standard bars?
A: The NBH2084 head features standard mounting holes (typically 20mm diameter). You can use the high-quality boring bars included in the set, or any standard 20mm cylindrical shank boring bar from other manufacturers, giving you maximum flexibility.
Q4: Does the set include the cutting inserts?
A:Yes. Our complete NBH2084 sets typically include a starter pack of indexable carbide inserts (such as TBGH or TPGH style) that fit the included boring bars, along with the necessary Torx wrenches and adjustment tools. Please specify the material you plan to machine so we can provide the optimal insert grade.
