The SCIENTIFIC CUTTING TOOLS B140500A is a solid carbide boring bar engineered for precision internal turning operations on small-diameter bores. Built from submicron carbide grade material and finished with an AlTiN plus coating, this bar delivers wear resistance and thermal stability in demanding machining environments. It cuts right-hand with a minimum bore diameter of 0.14 inches and a maximum bore depth of 0.5 inches. The 3/16-inch shank diameter and 2-inch overall length make it well suited for compact tooling setups on CNC lathes and small boring applications where tight tolerances are required.
This boring bar is intended for machinists and toolroom professionals working with small-bore internal features in materials that benefit from submicron carbide tooling, including hardened steels, stainless alloys, and non-ferrous metals. Its compact geometry is appropriate for applications where bore diameter constraints limit the use of larger tooling. Typical install scenarios include CNC lathe operations, screw machine work, and manual lathe finishing passes requiring close dimensional control.
Designed as an OEM-style replacement or direct tooling solution for CNC lathes and manual turning centers equipped with tool holders accepting a 3/16-inch shank boring bar.
This boring bar should be installed and set up by a qualified machinist familiar with internal turning tooling. Ensure the machine spindle is fully stopped and the machine is powered down before inserting or adjusting the bar in the tool holder. Confirm proper shank clamping and minimal overhang to reduce chatter and deflection. Follow the machine manufacturer's recommendations for speed, feed, and coolant application when using carbide tooling.
