Accupro ACC-BB140250G Boring Bar Solid Carbide Tin Coated

Product Description

The ACCUPRO ACC-BB140250G is a solid carbide boring bar designed for precision internal boring operations on small-diameter features. Manufactured from micrograin solid carbide with a titanium nitride (TiN) finish coating, this bar delivers extended tool life and consistent performance in demanding machining environments. It accepts a minimum bore diameter of 0.14 inches and reaches a maximum bore depth of 0.25 inches. The right-hand cutting direction suits standard CNC turning and manual lathe setups. With a 3/16-inch shank diameter and a 2-inch overall length, it fits compact toolholders and tight-clearance applications.

This boring bar is suited for machining small bores in ferrous and non-ferrous materials where tight dimensional tolerances are required. It is appropriate for production shops, tool rooms, and job shops running CNC lathes or manual turning equipment. The micrograin carbide substrate and TiN coating make it a practical choice for applications where tool wear and surface finish consistency are priorities. Machinists, tool-and-die makers, and CNC operators are the typical end users.

Key Features

• Micrograin solid carbide substrate for high rigidity and wear resistance in small-bore applications
• TiN finish coating extends cutting edge life and reduces built-up edge
• Right-hand cutting direction for standard turning setups
• 0.14-inch minimum bore diameter enables access to tight internal features
• 0.25-inch maximum bore depth suits shallow-cavity boring operations
• 3/16-inch shank diameter fits compact boring toolholders

Compatibility

Designed as a direct-fit boring bar for toolholders accepting a 3/16-inch round shank, suitable for CNC lathes and manual turning centers configured for right-hand internal boring operations.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the spindle before seating or removing the boring bar from the toolholder. Ensure the shank is fully engaged and the set screw is properly tightened to the toolholder manufacturer's specification before running. Verify bore depth and diameter against the workpiece drawing before initiating the cut.
