Value Collection 375-5152 Boring Bar M35 Cobalt Right Hand

Product Description

The VALUE COLLECTION 375-5152 is a right-hand boring bar machined from M35 cobalt high-speed steel, designed for internal boring operations on metalworking lathes and turning centers. It accepts a minimum bore diameter of 0.625 inches and reaches a maximum bore depth of 1.875 inches, making it well-suited for precision finishing and sizing of short bores. The 0.75-inch shank diameter provides rigid tool holding in standard boring bar holders. At 3.625 inches overall length, this bar balances reach and stiffness to reduce chatter during the cut. M35 cobalt grade offers elevated heat resistance compared to standard M2 HSS, supporting higher cutting speeds in steel, cast iron, and similar workpiece materials.

This boring bar is intended for use in manual and CNC lathes, turret lathes, and turning centers where right-hand cutting direction is required. It is a general-purpose internal machining tool for job shops, tool rooms, and production environments handling small to medium bores in ferrous and non-ferrous materials. Its compact maximum bore depth suits through-bore and blind-bore finishing passes in workpieces where a short reach is sufficient.

Key Features

• M35 cobalt construction for improved heat and wear resistance over standard HSS
• Minimum bore diameter of 0.625 inches suits small-bore finishing applications
• Maximum bore depth of 1.875 inches for short through and blind bore work
• 0.75-inch shank diameter for secure clamping in standard boring bar holders
• Right-hand cutting direction for conventional lathe setups
• 3.625 inches overall length balances reach with rigidity to minimize deflection

Compatibility

Designed as a direct-fit replacement or standard tooling option for any lathe or turning center equipped with a boring bar holder accepting a 0.75-inch shank diameter and right-hand cutting geometry.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or adjusting the boring bar. Secure the shank firmly in the tool holder with adequate overhang minimized to reduce deflection. Verify bore diameter and depth settings with appropriate gauging before taking finish passes.
