Value Collection 375-5076 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5076 is a right-hand boring bar designed for precision internal boring operations on the lathe or boring machine. Constructed from M35 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard M2 HSS tooling, making it suitable for harder workpiece materials and interrupted cuts. The bar has a 0.5 inch minimum bore diameter, a maximum bore depth of 2.5 inches, a 0.5 inch round shank, and an overall length of 3.875 inches. It is a solid single-point tool intended for machinists and toolroom technicians who need a reliable, ready-to-grind or ready-to-use boring solution.

This boring bar is suited for small-bore internal turning work in job shop, toolroom, and production environments. The 0.5 inch shank fits standard boring bar holders and quick-change tool posts commonly found on bench lathes and turret lathes. The right-hand cutting direction means the tool feeds from right to left in conventional lathe orientation. It is appropriate for finishing and semi-finishing bores in steel, stainless steel, cast iron, and other ferrous materials where the cobalt grade provides an advantage over standard HSS.

Key Features

• M35 cobalt HSS construction for improved heat resistance and longer tool life in demanding cuts
• Right-hand cutting direction for standard lathe right-to-left feed operations
• 0.5 inch minimum bore diameter accommodates small internal bore work
• 2.5 inch maximum bore depth provides reach for moderate-depth bores
• 0.5 inch round shank fits widely available boring bar holders and quick-change posts
• 3.875 inch overall length for compact, rigid setup in small lathes and turret machines

Compatibility

Designed as a direct-fit replacement or toolroom addition for 0.5 inch boring bar holders and quick-change tool post systems accepting 0.5 inch round shank boring bars.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the lathe or boring machine before seating or adjusting the tool in the holder. Ensure the cutting edge is set on or slightly above centerline to avoid rubbing and poor finish. Tighten the holder set screws to the tool post manufacturer specification using the appropriate hex key before resuming machine operation.
