Value Collection 375-1256 Boring Bar C6 Carbide-tipped

Product Description

The VALUE COLLECTION 375-1256 is a right-hand carbide-tipped boring bar designed for precision internal boring operations on lathes and boring machines. It features a C6 carbide-tipped insert grade, suited for general-purpose machining of cast iron, steel, and non-ferrous materials at moderate cutting speeds. The shank diameter is 0.5 inches, the minimum bore diameter is 0.4375 inches (7/16 inches), and the maximum bore depth reaches 1.6875 inches (1-11/16 inches). Overall length is 3-3/16 inches. Machinists and toolroom technicians use this bar for finishing and semi-finishing passes where dimensional accuracy and surface finish are the primary objectives.

This boring bar fits standard lathe toolposts and boring setups that accept a 0.5-inch shank. It is appropriate for small-bore applications in job shop, production, and maintenance machining environments. The right-hand cutting direction means the tool cuts when feeding from right to left toward the headstock, which is the standard configuration for most conventional lathe boring work. It is sold individually and suited for both manual and CNC lathe applications where the bore size range falls within its stated capacity.

Key Features

• C6 carbide-tipped grade for general-purpose machining of ferrous and non-ferrous materials
• Minimum bore diameter of 0.4375 inches (7/16 inches) for small-bore access
• Maximum bore depth of 1.6875 inches (1-11/16 inches)
• Right-hand cutting direction for standard lathe feed orientation
• 0.5-inch shank diameter fits common toolpost and boring head holders
• Compact 3-3/16-inch overall length for use in tight setups

Compatibility

Designed as an OEM-style replacement or standard toolroom boring bar for lathes and boring machines accepting a 0.5-inch shank diameter boring bar holder.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine before mounting or removing the boring bar from the toolpost or turret. Ensure the shank is clamped securely and that tool overhang does not exceed the maximum bore depth rating, as excessive overhang increases vibration and reduces dimensional accuracy. Inspect the carbide tip for chipping or wear before use.
