Value Collection 375-5120 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5120 is a right-hand boring bar designed for precision internal boring operations on metal workpieces. Constructed from M35 cobalt high-speed steel, this bar delivers strong wear resistance and heat tolerance, making it well suited for harder ferrous and non-ferrous materials. It accepts a minimum bore diameter of 0.375 inches and reaches a maximum bore depth of 1.125 inches. The 3/4-inch shank diameter provides rigid tool holding, and the 2-7/8-inch overall length fits compact tooling setups on lathes and boring machines. Machinists and tool-and-die technicians are the primary installers.

This boring bar is used in manual and CNC lathe applications for enlarging or finishing existing holes to close tolerances. It is appropriate for light to medium-duty internal turning operations in job shop, maintenance, and production environments. The right-hand cutting direction suits standard spindle rotation on most conventional lathes. It is sold individually and is well suited for prototype work, repair machining, and general-purpose boring tasks where cobalt tooling is preferred over standard high-speed steel.

Key Features

• M35 cobalt construction for improved heat and wear resistance over standard HSS
• Minimum bore diameter of 0.375 inches for small-hole internal turning
• Maximum bore depth of 1.125 inches
• 3/4-inch shank diameter for rigid, stable tool holding
• Right-hand cutting direction for standard lathe spindle rotation
• 2-7/8-inch overall length for compact toolpost setups

Compatibility

Designed as a direct-fit boring bar for tool holders accepting a 3/4-inch round shank, compatible with manual and CNC lathes configured for right-hand internal boring operations.

Installation Notes

Installation is performed by qualified machinists following standard lathe tooling setup procedures. Power down and lock out the machine before mounting or adjusting the boring bar in the tool holder. Ensure the shank is clamped securely and the cutting edge is set on center with the workpiece axis. Follow applicable shop safety standards and machine manufacturer guidelines during setup and operation.
