Value Collection 375-5016 Boring Bar M35 Cobalt 1/4 in

Product Description

The VALUE COLLECTION 375-5016 is a right-hand boring bar designed for precision internal boring operations in metal cutting applications. Manufactured from M35 cobalt high-speed steel, this bar offers enhanced heat and wear resistance compared to standard HSS tooling, making it well-suited for harder workpiece materials. It accepts a minimum bore diameter of 0.25 inches and reaches a maximum bore depth of 0.75 inches, with a 2-inch overall length and a 3/8-inch shank diameter. Machinists and tool-and-die professionals will find this bar straightforward to set up in standard boring head or tool post configurations.

This boring bar is intended for light-duty internal boring on manual lathes, CNC turning centers, and boring head setups where small bore diameters and relatively shallow depths are required. It is appropriate for production shops, toolrooms, and maintenance machining environments. The right-hand cutting direction suits conventional lathe setups where the tool feeds from right to left toward the chuck.

Key Features

• M35 cobalt construction provides superior hardness and heat resistance over standard M2 HSS
• Minimum bore diameter of 0.25 inches for small internal features
• Maximum bore depth of 0.75 inches suits shallow-cavity applications
• 3/8-inch shank diameter fits common boring head and tool post holders
• Right-hand cutting direction for standard lathe feed orientation
• Compact 2-inch overall length for close-clearance setups

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for tool holders and boring heads accepting a 3/8-inch round shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in the tool holder to the full recommended engagement depth to minimize overhang and chatter. Ensure the cutting edge is set on centerline of the workpiece before beginning the bore. Power down and lock out the machine spindle before making any tool changes or adjustments.
