Steel Reduced Shank Precision Boring Tools, Size: 2-4 mm, Automation Grade: Semi-Automatic

A precision boring head is a versatile, adjustable machining tool used with a mill or jig borer to enlarge, straighten, or finish pre-drilled holes to extremely tight tolerances and smooth finishes, featuring a single-point cutter mounted in a head with fine-adjustment screws for precise diameter control, crucial for industries like aerospace, automotive, and mold making. These heads typically have interchangeable shanks for different machines, hardened components for rigidity, and internal cooling for performance, allowing for roughing to finishing cuts.
