Value Collection 375-5080 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5080 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 delivers solid heat and wear resistance during demanding cutting cycles. It handles a minimum bore diameter of 0.375 inches and a maximum bore depth of 1.125 inches. The 5/8-inch shank diameter provides a stable mounting platform, while the 2.625-inch overall length keeps the bar rigid in the tool holder. Machinists and tool-and-die professionals use this style of bar for finishing and semi-finishing bores in ferrous and non-ferrous materials.

This boring bar suits small-bore applications on manual and CNC lathes, turret lathes, and boring mills where bore diameter starts at 3/8 inches. The right-hand cutting direction makes it compatible with standard forward-rotation setups. It is a practical choice for job shops, maintenance machining, and production environments that require consistent bore geometry without specialized tooling.

Key Features

• M35 cobalt steel construction for improved heat resistance and extended tool life over standard HSS
• Minimum bore diameter of 3/8 inches (0.375 inches) for small-bore work
• Maximum bore depth of 1-1/8 inches (1.125 inches)
• 5/8-inch shank diameter for secure clamping in standard tool holders
• Right-hand cutting direction for conventional forward-rotation setups
• Compact 2-5/8-inch overall length reduces overhang and chatter risk

Compatibility

Designed for use in standard boring bar holders and tool posts accepting a 5/8-inch shank, on manual or CNC lathes configured for right-hand cutting.

Installation Notes

Installation is performed by qualified machinists. Power down and lock out the machine before mounting or removing the boring bar. Secure the shank firmly in the tool holder with adequate clamping length to minimize deflection during the cut. Inspect the cutting edge for wear or chipping before each use and replace the bar if the edge is compromised.
