Value Collection 375-5044 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5044 is a right-hand boring bar designed for precision internal turning and bore finishing operations on lathes and boring machines. Constructed from M35 cobalt high-speed steel, it delivers enhanced heat and wear resistance compared to standard M2 tooling, making it a practical choice for machining harder workpieces and interrupted cuts. The bar has a 0.25-inch minimum bore diameter and reaches a maximum bore depth of 1.25 inches, with a 0.5-inch shank diameter and an overall length of 2.625 inches. It is installed by machinists and toolroom technicians working in production or job-shop environments.

This boring bar is suited for small-diameter internal boring work on manual engine lathes, turret lathes, and CNC turning centers equipped with the appropriate tool block or holder. The 0.5-inch shank seats in standard boring bar holders and quick-change toolpost systems that accept that shank size. The right-hand cutting direction means it cuts toward the headstock on a conventional lathe setup, which is the standard orientation for the majority of internal boring applications in light to medium material removal work.

Key Features

• M35 cobalt construction for improved red hardness and wear resistance over standard HSS
• 0.25-inch minimum bore diameter for accessing small internal diameters
• 1.25-inch maximum bore depth suitable for shallow to moderate internal features
• 0.5-inch shank diameter fits standard boring bar holders and quick-change toolposts
• Right-hand cutting direction for conventional lathe boring toward the headstock
• Compact 2.625-inch overall length reduces overhang and chatter in tight setups

Compatibility

Designed for use in standard boring bar holders and quick-change toolpost systems that accept a 0.5-inch shank diameter on manual or CNC turning equipment.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine before mounting or adjusting the boring bar in the holder. Ensure the shank is fully seated and clamped to the correct torque per the toolpost manufacturer specification before taking a cut. Verify the cutting edge is set to the correct center height relative to the workpiece centerline before engaging the feed.
