Accupro ACC-BBL140800 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL140800 is a left-hand cut boring bar ground from submicron-grade solid carbide and intended for precision internal boring operations on CNC lathes and manual turning centers. It accepts a minimum bore diameter of 0.14 inches and reaches a maximum bore depth of 0.8 inches. The shank diameter is 3/16 inches and the overall length is 2 inches. A bright finish provides a smooth surface that reduces built-up edge and aids chip evacuation during cutting. Machinists and toolroom technicians use this bar when close-tolerance hole sizing is required in small-diameter bores.

This boring bar is suited for small-bore finishing and semi-finishing passes on ferrous and non-ferrous workpieces where tight diameter tolerances and smooth surface finish are priorities. The left-hand cutting direction makes it appropriate for specific lathe setups requiring reverse-rotation tooling or back-boring configurations. At 2 inches overall length, it fits compact tooling blocks and quick-change holders sized for a 3/16-inch shank. Machine shops, tool and die operations, and production turning cells are the typical environments for this tool.

Key Features

• Submicron-grade solid carbide construction for increased hardness and wear resistance compared to standard carbide grades
• Left-hand cutting direction supports reverse-rotation and back-boring setups
• 0.14-inch minimum bore diameter enables work in very small internal diameters
• 0.8-inch maximum bore depth suits short, precise boring passes
• Bright finish reduces friction and inhibits built-up edge on the cutting edge
• 3/16-inch shank fits a wide range of compact boring tool holders and quick-change systems

Compatibility

Designed as an OEM-style replacement or direct fitment boring bar for lathes and turning centers that accept a 3/16-inch shank boring tool holder with left-hand cutting orientation.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing any cutting tool. Seat the shank fully in the tool holder and torque the clamping screws evenly according to the holder manufacturer's specifications. Verify tool overhang does not exceed the holder's recommended length-to-diameter ratio to minimize chatter and deflection during the boring pass.
