Value Collection 375-5108 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5108 is a right-hand boring bar designed for internal diameter machining operations on metal workpieces. Constructed from M35 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard M2 tooling, making it well suited for harder steels, stainless alloys, and interrupted cuts. The bar accepts a minimum bore diameter of 9/16 inches and reaches a maximum bore depth of 2-13/16 inches, with a 5/8 inch shank diameter and an overall length of 4-5/16 inches. Machinists and toolroom technicians use this bar in manual lathes, CNC turning centers, and boring mills where precise internal diameter sizing is required.

This boring bar is appropriate for production and job-shop environments handling ferrous and non-ferrous materials that demand a tougher tool substrate. Its right-hand cutting direction suits standard spindle rotation setups on conventional and CNC lathes. The 5/8 inch shank fits common tool post and boring head holders. It is a practical choice for general-purpose line boring, counter-boring, and diameter finishing where M35 cobalt grade material provides an advantage over standard high-speed steel in terms of edge retention and tool life.

Key Features

• M35 cobalt high-speed steel construction for improved heat resistance and edge retention
• Right-hand cutting direction for standard lathe and turning center setups
• Minimum bore diameter of 9/16 inches suits a range of small to mid-size bore applications
• Maximum bore depth of 2-13/16 inches allows reach into deeper workpiece cavities
• 5/8 inch shank diameter fits widely available tool holders and boring head systems
• 4-5/16 inch overall length provides rigid tool support while maintaining workpiece clearance

Compatibility

Designed as a direct-fit replacement or addition for standard 5/8 inch shank tool holders used in manual and CNC lathes, turning centers, and boring mills requiring right-hand boring bar tooling.

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 reduce chatter. Ensure the machine spindle is fully stopped and the lathe or machining center is powered down before changing or adjusting tooling. Verify cutting edge orientation and tool height alignment before commencing a bore operation.
