Value Collection 35574235 A2 Tool Steel Round Bar 5/8 in 3 Ft

Product Description

The VALUE COLLECTION 35574235 is a decarb-free A2 air-hardening tool steel round bar intended for toolmakers, machinists, and die makers who require a ready-to-machine blank with a clean, scale-free surface. At 5/8 inch in diameter and 3 feet in stock length, this round ships as a single piece ready for layout, turning, or milling. The A2 grade offers a balance of wear resistance and toughness that makes it a practical choice for punches, dies, gauges, and similar precision tool applications. Diameter tolerance is held to plus 0.005 to minus 0.015 inch, supporting close-tolerance machining without an additional cleanup pass on the outside diameter.

This round bar is suited for job shops, tool rooms, and maintenance departments that stock raw material for on-demand tool fabrication. Stock-length bar is a standard starting point for punch and die work, jig components, fixture pins, and forming tools in both light manufacturing and heavy industrial settings. The decarb-free condition means the outer surface retains full hardness after heat treatment, eliminating the extra stock removal required with standard mill-finish bar stock.

Key Features

• A2 air-hardening tool steel grade provides good wear resistance with moderate toughness
• Decarb-free surface condition preserves full hardness through to the outer diameter after heat treatment
• Diameter tolerance of plus 0.005 to minus 0.015 inch supports close-tolerance machining
• 5/8 inch diameter by 3-foot stock length ships as a single ready-to-cut piece
• UNSPSC Code 20102105 for procurement and inventory classification

Compatibility

Designed as a general-purpose raw material blank compatible with conventional lathes, mills, grinders, and EDM equipment used in tool and die fabrication environments.

Installation Notes

Cutting and machining of tool steel round bar should be performed by qualified machinists using appropriate speeds, feeds, and cutting fluids for the A2 grade. Secure the workpiece firmly in a chuck or collet before any turning or milling operation. Heat treatment, including hardening and tempering of A2 steel, should follow the material manufacturer's recommended thermal cycle and must be performed in a controlled atmosphere or vacuum furnace to protect the decarb-free surface. Always wear appropriate PPE when cutting or grinding tool steel.
