SDUCR L Internal Turning Tool

This SDUCR L Boring Bar is built with a screw locking design that keeps the insert locked in place where you set it. Force distributes evenly across the insert face, giving you secure clamping that stays tight throughout the cut. No loosening, no displacement, no chipping risk-just stable cutting that keeps your dimensions accurate and your parts consistent. Whether you're taking semi-finish passes or dialing in that final finish bore, this bar handles internal machining operations without the surprises that cost you time and material.

The boring bar body is high-quality alloy tool steel, heat-treated and quenched to spec. It's got the hardness to resist wear and the toughness to take the abuse that comes with internal work. The anti-vibration groove design is what makes this Indexable Lathe Boring Bar stand out-it actively suppresses the chatter that destroys surface finish and burns up inserts when you're boring deep holes. Your workpieces come out smoother, your tools last longer, and you spend less time fighting harmonic vibration that makes precision work frustrating.

Surface treatment is black oxide anti-rust finish. That matters in a real shop environment where humidity and cutting oil create corrosion problems. This bar won't turn into a rusted mess sitting in the tool crib between jobs. Even after months of storage, it comes out ready to work without pitting or surface damage that affects accuracy.

The small-size S12 shank diameter is designed for smaller hole machining. When you need precision in tight spaces, this bar gets in where larger tools can't reach. Installation is straightforward, positioning is accurate, and you spend less time fighting setup and more time making good parts. For small-hole boring requirements, this is the tool that gets the job done.

The economics work in your favor. Indexable insert design means when the cutting edge finally wears out, you pop in a new insert and keep cutting. The bar stays in the machine. You don't throw away money replacing whole boring bars, and your consumable costs drop significantly over time. For internal boring operations, this is practical economics that keeps a shop running profitably without sacrificing quality.
