The ACCUPRO B2001000R is a corner radius boring bar machined from submicron-grade solid carbide, designed for precision internal turning and boring operations on CNC lathes and machining centers. It delivers a minimum bore diameter of 0.2 inches and a maximum bore depth of 1 inch. The bright finish coating helps reduce built-up edge and improves chip flow in tight-tolerance bores. With a 0.25-inch shank diameter and an overall length of 2.5 inches, this bar is sized for compact tooling setups where rigidity and reach must be carefully balanced. A corner radius range of 0.005 to 0.008 inches allows for controlled surface finish on the bore wall without sharp-corner stress risers.
This boring bar suits right-hand cutting applications in production and job-shop environments. It is appropriate for finishing passes in ferrous and non-ferrous materials where consistent corner geometry is required. The submicron carbide substrate provides the hardness and fracture resistance needed for interrupted cuts and fine-chip operations at elevated cutting speeds. Machinists and tooling technicians working with small-bore components will find the compact shank useful in gang-tooling and turret configurations.
Designed as an OEM-style solid carbide boring bar for use in standard 0.25-inch shank boring bar holders on CNC lathes, gang-tool slides, and turret tooling blocks that accept right-hand boring bars.
Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the turret or tooling block is de-energized before mounting or removing the bar. Seat the shank fully in the holder and verify that clamping screws achieve uniform contact to prevent deflection during the cut. Do not exceed the holder manufacturer's recommended overhang ratio for the shank diameter.
