Value Collection 630-0050 Angle Block 0.5 Degree 3 Inch

Product Description

The VALUE COLLECTION 630-0050 is a hardened steel angle block used for precision setup and inspection work in machining, grinding, and metrology applications. This block holds a fixed 0.5-degree angle and measures 3 inches in overall length. With a surface hardness of 57 HRC, it resists wear and maintains dimensional stability under repeated use. Machinists and tool room technicians use angle blocks to set compound angles, support workpieces at precise inclinations, and verify angular accuracy on surface plates and machine tool setups. The 20-second angular accuracy rating makes this block suitable for demanding tolerancing work.

This angle block is suited for use in production machine shops, tool and die rooms, and quality inspection environments. It is commonly used in conjunction with sine bars, surface plates, and granite inspection tables to establish consistent angular references. The 3-inch length provides a stable base for supporting small to medium workpieces during surface grinding, EDM setup, or CMM staging operations. Typical users include machinists, tool makers, and metrology technicians working in both job-shop and production settings.

Key Features

• Fixed 0.5-degree angle for repeatable angular setups
• 57 HRC hardness resists wear and maintains accuracy over time
• 3-inch overall length provides a stable, workable base
• 20-second angular accuracy for precision inspection and setup use
• Compact form works alongside sine bars and surface plates

Compatibility

Designed as a standard angle block for general-purpose precision setup and inspection use on surface plates and machine tools.

Installation Notes

Angle blocks are positioned by hand on surface plates or machine tables and do not require fastening for most setup applications. Keep contact surfaces clean and free of burrs or debris before use to preserve angular accuracy. Store the block in a protective case or with a light coat of rust-preventive oil when not in use. No special tools or trade certifications are required for standard metrology and setup applications.
