The MIR3–MIR8 small bore boring bars and A60 solid carbide internal threading tool are precision-engineered for micro-diameter internal machining applications.
Designed for high accuracy and stability, these tools are ideal for small hole boring, internal turning, and threading operations. The solid carbide construction ensures excellent rigidity and vibration resistance, enabling consistent performance even in deep or narrow-hole machining.
MIR3–MIR8 Small Bore Boring Bars & A60 Solid Carbide Internal Threading Tool for Small Hole MachiningCore Advantages:
1. We own our CNC machining factory, and all cutting tools we sell are released only after long-term in-house testing and actual production use.
2. The surface finish, durability, and precision of our tools have been thoroughly verified through extended machining applications.
3. For bulk purchases, please contact us directly for pricing details.
Recommendations for Use
1. Before using the tool, please check the tool runout. If the runout exceeds 0.01 mm, correct it before machining.
2. The shorter the tool overhang from the holder, the better. If a longer overhang is required, reduce the spindle speed, feed rate, or cutting depth accordingly.
3. If abnormal vibration or noise occurs during cutting, reduce the spindle speed and cutting parameters until the condition improves.
4. For aluminum machining, air blast with cutting fluid is recommended, as it can effectively improve the performance and tool life of the milling cutter.
