Value Collection 375-5124 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5124 is a right-hand boring bar designed for precision internal boring operations on lathes and boring machines. Constructed from M35 cobalt high-speed steel, this bar handles tough materials and interrupted cuts better than standard M2 tooling. It carries a minimum bore diameter of 0.375 inches and a maximum bore depth of 1.875 inches, making it suited for small-diameter finish and semi-finish boring work. The 0.75-inch shank diameter provides rigid clamping in standard tool posts and boring heads. Overall length is 3.625 inches. Machinists and toolroom operators reach for this bar when holding tight tolerances on internal diameters in steel, cast iron, and similar ferrous workpieces.

This boring bar fits production and job-shop turning applications where a compact, right-hand internal boring tool is required. It is appropriate for use in manual lathes, CNC turning centers, and horizontal boring setups where the 0.75-inch shank interfaces with standard tool holders. The 1.875-inch maximum bore depth suits shallow-to-medium cavity work, including bearing bores, bushing seats, and precision-fit housings. The M35 cobalt composition extends tool life in harder alloy steels compared to standard HSS grades.

Key Features

• M35 cobalt construction for improved heat and wear resistance over standard HSS
• Minimum bore diameter of 0.375 inches for small internal bore applications
• Maximum bore depth of 1.875 inches suits shallow and medium-depth cavities
• 0.75-inch shank diameter fits standard tool posts and boring head holders
• Right-hand cutting direction for conventional lathe setups
• Overall length of 3.625 inches for compact tool overhang

Compatibility

Designed as a standard right-hand boring bar for use in tool holders and boring heads that accept a 0.75-inch round shank, suitable for manual and CNC turning center applications.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully within the tool holder to minimize overhang and reduce chatter. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bar. Follow shop-standard tool-setting procedures for center height alignment prior to taking a cut.
