Rigibore R12F5 Angular Mounted 90 Degree Approach Boring Bar

The Rigibore R12F5 Angular Mounted 90° Approach Boring Bar is a specialized cutting tool designed for precision boring where a 90-degree approach into the workpiece is required. Built around Rigibore's angular-mount concept, this unit is described as having an Insert Special, indicating a customized insert configuration tailored to specific materials or hole tolerances. The 90° approach and angular mounting provide rigid guidance and stable bore geometry in bores that are difficult to reach with conventional straight bars, helping maintain concentricity and finish quality in tight recesses. The R12F5 designation identifies the bore-unit family within Rigibore's product line, signaling a particular combination of insert geometry and mounting style that can be paired with Rigibore's range of compatible inserts. This boring bar is intended for finishing operations where traditional tooling cannot access the bore from a straight approach, enabling precise hole geometry without repositioning the workpiece. Operators select the correct Insert Special for the task at hand, allowing the tool to adapt to material hardness and desired surface finish while preserving tolerance control during boring cycles.
