Value Collection 630-4305 Angle Block 5 Degree 3 Inch

Product Description

The VALUE COLLECTION 630-4305 is a precision angle block machined to a fixed 5-degree angle and measuring 3 inches in overall length. Angle blocks are used in metalworking and inspection environments to set, hold, or verify workpieces at a precise angular relationship to a surface plate or machine table. This block is hardened to 55 HRC, providing the wear resistance and dimensional stability required for repeated use in production or toolroom settings. Accuracy is rated to 20 arc seconds, making it suitable for close-tolerance setups in grinding, milling, and inspection work. At 0.2 pounds, it is a compact and easily handled precision tool.

This angle block is commonly used by machinists, tool and die makers, and quality control technicians working in job shops, tool rooms, and manufacturing facilities. Typical applications include setting workpiece angles on surface grinders, establishing reference angles for CMM fixturing, and verifying angular accuracy during inspection. The fixed 5-degree angle makes it a dedicated reference standard for setups that require that specific inclination repeatedly and reliably.

Key Features

• Fixed 5-degree angle for repeatable, dedicated angular setups
• 3-inch overall length provides a stable reference surface
• 55 HRC hardness resists wear and maintains dimensional accuracy over time
• Accuracy rated to 20 arc seconds for close-tolerance work
• Lightweight at 0.2 pounds for easy handling and positioning

Compatibility

Designed as a standard precision angle block suitable for use with surface plates, magnetic chucks, and machine tool fixtures in general metalworking and inspection applications.

Installation Notes

Angle blocks are positioned and secured by a machinist or metrology technician — no power tools or electrical shutoff is required for typical use. Keep reference surfaces clean and free of burrs or chips before seating the block to avoid measurement error. Store the block in a protective case when not in use to prevent surface damage that could compromise accuracy. Periodic recalibration against a traceable standard is recommended in quality-controlled environments.
