Scientific Cutting Tools BB2514 Radial Relief Boring Bar

Product Description

The SCIENTIFIC CUTTING TOOLS BB2514 is a radial relief boring bar machined from submicron-grade solid carbide for internal diameter turning and boring operations. It features a 0.248 inch minimum bore diameter and a maximum bore depth of 1.5 inches, making it well suited to tight-tolerance small-bore work. The right-hand cutting direction and uncoated carbide construction are standard for this tool class. A 0.25 inch shank diameter and 2.5 inch overall length keep the setup compact. This tool is typically installed by machinists and toolroom operators working on CNC lathes or manual turning centers.

This boring bar is intended for small-bore internal turning applications where close dimensional control is required. The submicron solid carbide substrate provides the rigidity and wear resistance needed when machining ferrous and non-ferrous materials in shallow-to-moderate bore depths. Typical use scenarios include finish boring bores approaching 0.248 inches in diameter in production or prototype machining environments. The radial relief geometry helps reduce cutting forces and allows clean chip evacuation in confined bore conditions.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in small-bore applications
• 0.248 inch minimum bore diameter supports tight-tolerance internal turning work
• Maximum bore depth of 1.5 inches accommodates moderate-depth boring passes
• Right-hand cutting direction - confirm spindle rotation before mounting
• Uncoated finish maintains sharp edge geometry without coating buildup in small bores
• 0.25 inch shank diameter fits standard small-bore boring bar holders and tool blocks

Compatibility

Designed as an OEM-style replacement and standard tooling option for small-bore boring bar holders accepting a 0.25 inch shank diameter in CNC lathe and manual turning center setups.

Installation Notes

A qualified machinist should install and set this boring bar in the appropriate tool holder, ensuring the shank is fully clamped and the cutting edge is on center before engaging the workpiece. Power down and lock out the machine spindle before making any tool changes or adjustments. Verify cutting direction and spindle rotation match the right-hand designation of this tool prior to operation. Follow the machine manufacturer and shop safety guidelines for boring bar overhang and feed rate selection.
