The ones our customers buy most.Description
The Omega Products Boring Bar with Carbide Shank is a precision tool designed for left-hand internal boring on CNC lathes and milling centers. With a 93-degree geometry and through-coolant capability, it delivers stable cuts, clean bores, and extended tool life across common DCMT11T3 and DCGT11T3 inserts.
- Left-Hand 93° Boring Geometry: Optimizes entry into bores with predictable chip flow and smooth cutting action for precise internal work.
- Carbide Shank: Rigid, stable performance that minimizes deflection at high speeds for tight tolerances and consistent runout.
- Through-Coolant Design: Direct cooling to the cutting edge improves heat dissipation, extends tool life, and enhances surface finish.
- Insert Compatibility: Engineered for DCMT11T3 and DCGT11T3 inserts, offering versatile performance across various materials.
- Designation: E20S SDUCL 11, ensuring a correct fit within compatible tool holders and setups.
This boring bar is built to boost productivity without compromising accuracy. The carbide shank provides the rigidity needed for high-speed machining, while through-coolant cooling helps maintain bore quality under demanding cutting conditions. Its compatibility with widely used DCMT and DCGT insert styles makes it a versatile choice for diverse projects, from precision automotive components to general-purpose bore work. By combining robust geometry, advanced materials, and efficient cooling, it helps reduce rework, extend tool life, and keep tolerances tight across a range of bore diameters and materials.
