Internal Tool 10-1460-A Boring Bar Micrograin Carbide

Product Description

The INTERNAL TOOL 10-1460-A is a solid carbide boring bar designed for precision internal bore operations on CNC and manual lathes. Built from micrograin carbide, this right-hand cutting bar handles a minimum bore diameter of 0.3200 inches with a maximum bore depth of 0.75 inches. The 3/8-inch shank diameter and 2.5-inch overall length make it a compact, rigid tool suited for tight-tolerance work in small-bore applications. Machinists and toolroom professionals use it where high wear resistance and dimensional stability are required across a broad range of workpiece materials.

This boring bar is suited for general-purpose internal boring in both production and job-shop environments. Its universal primary workpiece material rating means it performs across steel, aluminum, cast iron, and non-ferrous alloys without requiring a specialized grade change. The right-hand cutting direction is the standard orientation for conventional lathe setups. With a 4-degree relief angle and a 1.5-degree bar end angle, the geometry is optimized for clean bore finishes in shallow-to-moderate depth applications where a 0.75-inch maximum bore depth is sufficient.

Key Features

• Micrograin solid carbide construction for high wear resistance and edge retention
• Minimum bore diameter of 0.3200 inches enables work in small, tight bores
• Right-hand cutting direction for standard lathe orientation
• 4-degree relief angle and 1.5-degree bar end angle for clean surface finish
• 3/8-inch shank diameter fits standard boring bar holders and quick-change toolposts
• Universal workpiece material rating suitable for ferrous and non-ferrous applications

Compatibility

Designed as an OEM-style replacement or direct-use boring bar compatible with standard 3/8-inch boring bar holders and tool blocks on CNC lathes, manual engine lathes, and turret lathes requiring a minimum bore diameter of 0.3200 inches.

Installation Notes

Installation is performed by qualified machinists. Secure the 3/8-inch shank firmly in the boring bar holder, minimizing overhang to reduce chatter and deflection. Ensure the cutting edge is set on or slightly above centerline before taking a cut. Follow your machine tool manufacturer and shop safety guidelines when setting speeds, feeds, and depth of cut for carbide tooling.
