Scientific Cutting Tools B100400 Boring Bar Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS B100400 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide, it delivers consistent rigidity and edge retention in small-bore applications where deflection control is critical. The right-hand cutting direction suits standard spindle rotation setups. With a minimum bore diameter of 0.1 inches and a 0.125-inch shank diameter, this bar is suited for tight-tolerance work in small bores where high-speed steel tooling lacks the stiffness required.

This boring bar is used in precision machining environments including job shops, production turning cells, and toolroom operations. It handles small internal diameters in ferrous and non-ferrous workpieces where fine surface finish and dimensional accuracy are the priority. The 0.4-inch maximum bore depth and 1.5-inch overall length make it appropriate for shallow-bore pass work on short-chucked or small-diameter parts. Machinists and CNC programmers working with Swiss-style machines, gang-tool lathes, or standard 2-axis turning equipment will find this bar fits common small-bore tooling setups.

Key Features

• Submicron-grade solid carbide construction for stiffness and edge retention in small bores
• 0.1-inch minimum bore diameter for fine internal work
• 0.4-inch maximum bore depth suitable for shallow internal passes
• Right-hand cutting direction for standard spindle rotation
• 0.125-inch shank diameter fits common small-bore toolholders and collet systems
• Uncoated finish maintains sharp edge geometry out of the box

Compatibility

Designed as a direct-fit solid carbide boring bar for toolholders and collet blocks accepting a 0.125-inch round shank, commonly used in CNC turning, Swiss-style, and gang-tool lathe setups requiring 0.1-inch or larger bore diameters.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing tooling. Ensure the shank is properly seated and clamped to the full recommended engagement depth in the toolholder to minimize overhang deflection. Do not exceed the maximum bore depth rating, as overextension increases vibration and risk of tool breakage in carbide tooling.
