Accupro ACC-BB2001000G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB2001000G is a solid carbide boring bar designed for internal turning and bore finishing operations on CNC lathes and manual turning centers. Built from micrograin solid carbide, this bar delivers the rigidity and wear resistance needed for tight-tolerance work in production and toolroom environments. The 0.25 inch shank diameter and 2.5 inch overall length make it compact enough for small-bore applications, while the TiN (titanium nitride) finish coating extends cutting edge life. Right-hand cut geometry is suited for conventional boring pass direction. Machinists and CNC operators working on small-diameter internal features will find this bar well matched to their requirements.

This boring bar covers applications where minimum bore diameter starts at 0.2 inches and maximum bore depth reaches 1 inch. It is appropriate for use in steel, aluminum, cast iron, and similar machinable materials in light to medium material removal operations. Typical installations include CNC turning centers with 0.25 inch boring bar holders or compatible quick-change tooling blocks. The bar ships individually and is sold as a single unit.

Key Features

• Micrograin solid carbide construction for increased rigidity and wear resistance in small-bore work
• TiN finish coating extends tool life and reduces built-up edge on ferrous and non-ferrous materials
• 0.2 inch minimum bore diameter suits tight internal feature work
• 1 inch maximum bore depth provides reach for common small-part applications
• Right-hand cut geometry for standard boring pass direction
• Compact 0.25 inch shank diameter fits standard boring bar holders and quick-change tooling systems

Compatibility

Designed for use in CNC lathes and manual turning centers equipped with 0.25 inch boring bar holder pockets or compatible quick-change tooling blocks requiring a right-hand solid carbide boring bar.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing tooling. Ensure the shank is fully engaged in the holder and clamping screws are secured per the toolholder manufacturer specifications before any cutting pass. Verify minimum bore diameter clearance and maximum depth of cut against part requirements before initiating the operation.
