Indexable Internal Boring Bars with Insert & Key for CNC Lathe Machine (5/16" Shank)

• Precision SCLCR Series Performance: This Right-Hand (RH) indexable boring bar is engineered for high-accuracy internal turning. The SCLCR design is the industry standard for achieving tight tolerances and exceptional surface finishes in small to medium bores.
• High-Strength Hardened Shank: The 5/16" shank is crafted from premium alloy steel, hardened and tempered to 40-45 HRC. This process provides the essential rigidity needed to minimize tool chatter and prevent deflection during deep-hole operations.
• Optimized 95° Approach Angle: Featuring a 95-degree lead angle, this boring bar is ideal for both boring and facing to a square shoulder. The geometry ensures efficient chip flow and reduces cutting pressure, allowing for cleaner, more accurate cuts.
• Compact CCMT 06 Insert Compatibility: Designed to use standard CCMT 06 indexable carbide inserts (6 mm cutting edge). This indexable system allows for quick edge changes, ensuring your tool stays sharp without the need for manual regrinding.
• Versatile 4-3/4" Reach: With an overall length of 125 mm (4-3/4"), this tool provides ample reach for intricate internal work. Its compact 5/16" shank size makes it a perfect fit for smaller lathes, mini-lathes, and CNC turning centers.
• Comprehensive Tooling Set: The package includes everything needed for a professional setup: the 5/16" SCLCR boring bar, a precision clamping screw, and a T08 Torx wrench for secure and easy insert installation.
