Accupro ACC-BB2001200G Boring Bar 0.2 in Min Bore Solid Carbide

Product Description

The ACCUPRO ACC-BB2001200G is a solid carbide boring bar engineered for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide with a TiN (titanium nitride) finish coating, it delivers consistent cutting performance and extended tool life in ferrous and non-ferrous materials. The bar features a right-hand cutting direction, a minimum bore diameter of 0.2 inches, a maximum bore depth of 1-13/64 inches, a 1/4-inch shank diameter, and an overall length of 2-1/2 inches. Machinists and tool-and-die professionals use this bar where tight bore tolerances and fine surface finish are required.

This boring bar is suited for small-bore finishing and semi-finishing passes in precision machining environments. Its compact shank diameter and short overall length make it appropriate for tight-clearance bores in workholding fixtures, hydraulic components, valve bodies, and similar small-part applications. It is a single-piece, solid carbide design with no inserts to index or replace, making setup straightforward for production or job-shop use.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in precision boring
• TiN finish coating reduces friction and extends cutting edge life
• Right-hand cutting direction for standard lathe spindle rotation
• 0.2-inch minimum bore diameter enables work in very small internal diameters
• 1-13/64-inch maximum bore depth suitable for shallow-to-moderate bore lengths
• 1/4-inch shank diameter fits standard boring bar holders and quick-change tooling blocks

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/4-inch boring bar holders used in CNC turning centers and manual lathes requiring right-hand solid carbide boring bars.

Installation Notes

Installation is performed by qualified machinists or tooling setup personnel. The boring bar should be secured in a properly sized boring bar holder torqued per the machine tool manufacturer's toolholder specifications. Ensure the machine spindle is fully stopped and the lathe is in a locked or e-stop state before changing tooling. Confirm shank stick-out is minimized to reduce chatter and maintain bore accuracy.
