• Micrometer Accuracy Adjustment: Each division on the dial represents a accurate 0.0001" adjustment in diameter, allowing for direct, repeatable cuts and superior surface finishes in machining projects.
• Double Bar Holder For Expanded Range: The innovative dual-bar holder design significantly increases boring capacity. This setup allows for a wider range of bore diameters while maintaining tool rigidity and stability.
• Engineered For Minimal Backlash: This boring head features a accuracy gear train with a controlled backlash of only 10 divisions. This ensures more predictable and accurate movements when reversing the dial direction, suitable for achieving tight-tolerance work.
• H7 Accuracy Bore: The internal bore is machined to an H7 tolerance for a tight, secure fit with cutting tool shanks, minimizing vibration and runout.
• Versatile Boring Set: This all-in-one kit includes an R8 shank boring head and eight indexable 3/4" boring bars, providing a ready-to-use solution for a wide array of machining tasks.
