Scientific Cutting Tools PCD-B2001300 Corner Radius Boring Bar

Product Description

The SCIENTIFIC CUTTING TOOLS PCD-B2001300 is a corner radius boring bar designed for precision internal turning operations on CNC lathes and manual turning centers. With a minimum bore diameter of 0.2 inches and a maximum bore depth of 1.3 inches, this right-hand cut tool handles tight-bore applications where clearance and accuracy are critical. The 0.004-inch corner radius produces a controlled blend between bore walls and shoulders, reducing stress concentrations in finished bores. Machinists and toolroom operators rely on this type of bar for close-tolerance work in small-diameter bores where standard insert boring bars cannot reach.

This boring bar is suited for small-part machining in job shops, production turning cells, and toolroom environments. It performs well in applications involving aluminum, brass, plastics, and other materials that benefit from the uncoated finish. The 0.25-inch shank diameter fits standard boring bar holders and quick-change tooling systems commonly found on small to mid-size CNC turning centers and lathes. Right-hand cut orientation means the tool feeds from right to left in conventional lathe setup.

Key Features

• Corner radius of 0.004 inches for controlled surface blending in precision bores
• Minimum bore diameter of 0.2 inches for access to tight internal features
• Maximum bore depth of 1.3 inches to handle deeper small-diameter passages
• Right-hand cutting direction for standard lathe feed orientation
• Uncoated finish suitable for non-ferrous and non-abrasive materials
• Compact 0.25-inch shank diameter fits standard small-bore toolholders

Compatibility

Designed as an OEM-style replacement and standard fit for small-bore turning applications using 0.25-inch shank boring bar holders on CNC lathes and manual turning centers.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the boring bar. Ensure the shank is fully seated and clamped securely in the toolholder to the manufacturer-specified engagement depth to prevent chatter or pullout during cutting. Verify tool centerline height before commencing the boring operation.
