Accupro ACC-BBL4901250 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL4901250 is a left-hand cut boring bar machined from submicron-grade solid carbide. It is designed for internal bore finishing and sizing operations on lathes and boring machines. The bar features a 0.49-inch minimum bore diameter, a 1.25-inch maximum bore depth, a 0.5-inch shank diameter, and a 3-inch overall length. The bright finish coating provides a clean, uncoated surface suited to a range of workpiece materials. Machinists and toolroom professionals install this bar when a left-hand cutting direction is required for the application.

This boring bar is used in metalworking and machining environments where tight bore tolerances are needed. It is appropriate for both production and toolroom settings, including job shops, maintenance repair operations, and manufacturing facilities. The submicron carbide grade offers consistent edge integrity across interrupted cuts and abrasive materials. It is well suited for small-bore work where rigidity and dimensional accuracy are critical.

Key Features

• Submicron solid carbide construction for edge strength and wear resistance
• Left-hand cutting direction for specific lathe or boring machine setups
• 0.49-inch minimum bore diameter for small-bore applications
• 1.25-inch maximum bore depth
• 0.5-inch shank diameter with 3-inch overall length
• Bright finish coating — no additional surface treatment

Compatibility

Designed as an OEM-style replacement and standard tooling option for lathes and boring machines accepting a 0.5-inch shank boring bar with left-hand cut orientation.

Installation Notes

This boring bar is installed and serviced by qualified machinists. Ensure the machine spindle is fully stopped and locked out before changing or adjusting tooling. Confirm shank seating and tool holder clamping torque per the machine tool manufacturer specifications before beginning a cut. Do not exceed the rated maximum bore depth for this bar.
