Value Collection 375-5024 Boring Bar M35 Cobalt 3/8 Shank

Product Description

The VALUE COLLECTION 375-5024 is a right-hand boring bar designed for precision internal turning and bore enlargement operations on metal workpieces. Constructed from M35 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard M2 tooling, making it well suited for harder ferrous and non-ferrous materials. The bar features a 5/16 inch minimum bore diameter, a 15/16 inch maximum bore depth, and a 3/8 inch shank diameter. Overall length is 2-3/16 inches. Machinists and tool-and-die professionals use this bar when close-tolerance internal diameters are required in short, small-diameter bores.

This boring bar is appropriate for use on manual lathes, turret lathes, and CNC turning centers equipped with a compatible 3/8 inch tool holder or boring bar block. Its compact overall length and small minimum bore diameter make it practical for tight-clearance internal bore work in small components such as bushings, sleeves, and fittings across general machining, maintenance, and repair applications.

Key Features

• M35 cobalt construction provides improved red hardness and wear resistance over standard HSS
• 5/16 inch minimum bore diameter for small internal bore applications
• 15/16 inch maximum bore depth for short, precise cuts
• 3/8 inch shank diameter for standard tool holder compatibility
• Right-hand cutting direction for conventional lathe setup
• Compact 2-3/16 inch overall length for use in confined setups

Compatibility

Designed for use in 3/8 inch boring bar holders on manual and CNC turning equipment where right-hand internal boring operations are performed.

Installation Notes

Installation is performed by machinist or toolroom personnel. Secure the shank firmly in a compatible 3/8 inch boring bar holder or quick-change tool post, ensuring the cutting edge is set at the correct center height for the machine spindle. Power down and lock out the machine before changing or adjusting tooling. Inspect the cutting edge for wear or chipping before each use and replace tooling that shows damage to avoid workpiece damage or tool breakage.
