Value Collection 375-1856 Boring Bar C6 Carbide-tipped

Product Description

The VALUE COLLECTION 375-1856 is a right-hand carbide-tipped boring bar designed for internal diameter machining on lathes and boring mills. Built with a C6 carbide-tipped insert grade, it handles general-purpose turning and boring in cast iron, steel, and similar ferrous materials. The bar features a 1-inch shank diameter and a 7.75-inch overall length, providing rigidity for demanding cuts. With a minimum bore diameter of 1.25 inches and a maximum bore depth of 5.75 inches, it covers a practical range of internal machining operations. Machinists and tool room technicians install this bar in standard boring bar holders on manual and CNC turning equipment.

This boring bar is suited for shop floor and production machining environments where internal bores in the 1.25-inch and larger range are required. It is a right-hand cutting tool, meaning material is removed as the tool feeds toward the headstock in a conventional lathe setup. Typical applications include through-bores, stepped bores, and finish boring passes on workpieces held in chucks or fixtures. Its 5.75-inch maximum bore depth accommodates moderate-depth internal features without requiring a longer overhang setup.

Key Features

• C6 carbide-tipped construction for general-purpose boring in ferrous materials
• Right-hand cutting direction for standard lathe feed orientation
• 1.25-inch minimum bore diameter opens a wide range of internal feature sizes
• 5.75-inch maximum bore depth supports moderate through-bore and stepped-bore work
• 1-inch shank diameter fits standard boring bar holders and tool posts
• 7.75-inch overall length provides reach while maintaining tool rigidity

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for lathes and boring mills accepting a 1-inch shank diameter boring bar holder.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Power down and lock out the machine spindle before mounting or removing the boring bar. Secure the shank firmly in the boring bar holder to the full recommended engagement depth to minimize overhang and chatter. Verify tool height and alignment to centerline before taking a cut.
