Value Collection 375-5100 M35 Cobalt Boring Bar 5/8 Shank

Product Description

The VALUE COLLECTION 375-5100 is an M35 cobalt boring bar designed for precision internal turning and bore enlargement on metal workpieces. With a minimum bore diameter of 0.5 inches and a maximum bore depth of 2.5 inches, this right-hand cutting tool handles a practical range of interior machining operations. The 5/8-inch shank diameter provides rigid tool post clamping for reduced chatter and consistent dimensional accuracy. At 4 inches overall length and weighing 0.25 pounds, it fits standard lathe setups used in production and job shop environments. M35 cobalt construction gives the cutting edge improved heat and wear resistance compared to standard high-speed steel, making it a reliable choice for harder workpiece materials.

This boring bar is suited for manual and CNC lathes in machine shops, maintenance facilities, and toolroom environments. It is appropriate for right-hand boring operations where internal diameter finishing or roughing is required on ferrous and non-ferrous metals. The combination of cobalt grade material and a fixed shank profile makes it a straightforward drop-in tool for operators running conventional boring setups.

Key Features

• M35 cobalt material grade for enhanced heat resistance and edge retention
• Right-hand cutting direction for standard lathe boring operations
• 0.5 inches minimum bore diameter with 2.5 inches maximum bore depth
• 5/8 inches shank diameter for secure tool post or holder clamping
• 4 inches overall length for compact, rigid setup on bench and engine lathes
• Lightweight at 0.25 pounds for easy handling and quick tool changes

Compatibility

Designed as a standard replacement or supplemental boring bar for lathes and boring setups that accept a 5/8-inch shank with right-hand cutting orientation.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and fully de-energize the lathe before mounting the boring bar in the tool post or boring bar holder. Ensure the shank is clamped securely and the cutting edge is set on center height before beginning any cut. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tool overhang and feed rates.
