Accupro ACC-BB2001300A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB2001300A is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide with a TiAlN finish coating, it delivers consistent cutting performance and extended tool life in ferrous and non-ferrous materials. The right-hand cut geometry suits standard spindle rotation setups. With a 0.2-inch minimum bore diameter and 1.3-inch maximum bore depth, this bar handles tight, shallow bores where rigidity and accuracy are critical. The 0.25-inch shank diameter and 2.5-inch overall length make it a compact, easy-to-hold toolholder insert for production and job-shop environments. Machinists and CNC operators are the primary users.

This boring bar is suited for small-diameter internal finishing and semi-finishing passes in production machining, tool and die work, and repair operations. It performs in applications where bore tolerances are tight and surface finish requirements are high. The micrograin carbide substrate resists chipping and wear in interrupted and continuous cuts. Typical install scenarios include gang-tool lathes, turret lathes, and small CNC turning centers where a 0.25-inch shank fits the toolpost or holder block directly.

Key Features

• Micrograin solid carbide substrate for improved wear resistance and edge integrity
• TiAlN finish coating for extended tool life in dry and semi-dry cutting
• Right-hand cut geometry for standard spindle rotation compatibility
• 0.2-inch minimum bore diameter for tight, small-diameter internal operations
• 1.3-inch maximum bore depth suitable for shallow-to-moderate bore lengths
• 0.25-inch shank diameter fits common small-bore toolholders and turret blocks

Compatibility

Designed as an OEM-style replacement and standard fit for toolholders and turret blocks accepting a 0.25-inch round shank boring bar.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before mounting or adjusting the boring bar in the toolholder. Ensure the shank is seated to the recommended overhang length to maximize rigidity and minimize chatter. Do not exceed the maximum bore depth of 1.3 inches, as excessive overhang beyond rated depth reduces cutting stability and can damage the tool or workpiece.
