Value Collection 375-5084 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5084 is a right-hand boring bar designed for internal diameter boring operations on lathes and boring machines. Manufactured from M35 cobalt high-speed steel, it offers improved heat and wear resistance compared to standard M2 tooling, making it well suited for harder workpiece materials and interrupted cuts. The bar accepts a minimum bore diameter of 0.375 inches and reaches a maximum bore depth of 1.875 inches, with a 5/8-inch shank diameter for secure toolholder engagement. Overall length is 3.375 inches. Machinists and toolroom operators use this bar for precision ID work where consistent tool life and dimensional accuracy are required.

This boring bar is appropriate for light-to-medium duty internal turning operations in both production and job-shop environments. It fits standard right-hand boring bar holders with a 5/8-inch bore. Typical applications include finish boring of through-holes and blind holes in steel, cast iron, and alloy materials where M35 cobalt's elevated red-hardness provides an advantage over conventional HSS tooling.

Key Features

• M35 cobalt construction for improved heat resistance and extended tool life over standard HSS
• Minimum bore diameter of 0.375 inches enables work in tight internal diameters
• Maximum bore depth of 1.875 inches suits a range of through-hole and blind-hole applications
• 5/8-inch shank diameter provides rigid, consistent seating in compatible toolholders
• Right-hand cutting direction for standard lathe rotation
• Compact 3.375-inch overall length for use in confined toolpost setups

Compatibility

Designed for use in right-hand boring bar holders with a 5/8-inch shank bore on manual and CNC lathes or boring machines.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered off and in a locked-out state before mounting or adjusting tooling. The shank must be fully and evenly clamped in the toolholder to minimize overhang and chatter. Confirm that the cutting edge is set on or slightly above center height before taking a cut. Follow the machine manufacturer and shop safety guidelines for speeds and feeds appropriate to M35 cobalt tooling.
