Value Collection 375-1646 Boring Bar C6 Carbide-tipped

Product Description

The VALUE COLLECTION 375-1646 is a right-hand carbide-tipped boring bar designed for internal diameter turning and bore finishing operations on metalworking lathes. Built with a C6 carbide-tipped insert grade, it handles a range of ferrous and non-ferrous materials at moderate cutting speeds. The 3/4-inch shank diameter provides a rigid mount in standard tool holders, while the 9/16-inch minimum bore diameter makes it suitable for small-bore work. Overall length is 3.5 inches, keeping the tool compact for short-reach applications. Machinists and toolroom technicians use this bar for production turning, repair work, and custom bore sizing where a reliable, off-the-shelf tool is needed.

This boring bar fits standard lathe setups in job shops, maintenance facilities, and production machine shops. It is sized for light to medium boring passes, with a maximum bore depth of 1.5 inches. The right-hand cutting direction suits conventional lathe rotation for most standard turning operations. It is appropriate for use on manual engine lathes and turret lathes where the 3/4-inch shank is compatible with the tool post or boring head holder.

Key Features

• C6 carbide-tipped construction for wear resistance on ferrous and non-ferrous materials
• Minimum bore diameter of 9/16 inch suits small-bore internal turning operations
• Maximum bore depth of 1.5 inches for short to medium reach applications
• 3/4-inch shank diameter fits standard lathe tool holders and boring heads
• Right-hand cutting direction for conventional lathe rotation
• Compact 3.5-inch overall length reduces overhang and chatter risk

Compatibility

Designed as an OEM-style boring bar for use in standard lathe tool holders and boring heads that accept a 3/4-inch round shank.

Installation Notes

Installation is performed by qualified machinists familiar with lathe tooling setup. Power down and lock out the lathe spindle before mounting or adjusting the boring bar in the tool holder. Ensure the shank is clamped securely with sufficient engagement to prevent movement under cutting load. Follow standard shop safety practices and applicable machinery safety codes when operating cutting tools on a lathe.
