Value Collection 630-4303 Angle Block 3 Degrees 3 Inch

Product Description

The VALUE COLLECTION 630-4303 is a 3-degree angle block used for precision layout, inspection, and setup work in machine shops, toolrooms, and manufacturing environments. Ground to a 3-degree angle with an overall length of 3 inches, this hardened steel block provides a stable, accurate reference surface for angular measurement and workpiece positioning. The block is hardened to 55 HRC, delivering the surface durability required for repeated use in close-tolerance applications. Accuracy is rated to 20 arc seconds, making it suitable for demanding inspection and machining setups. Machinists and toolroom technicians are the primary users.

This angle block is suited for use on surface plates, milling machine tables, and inspection setups where a precise 3-degree angular reference is needed. Typical applications include setting compound angles, checking angular surfaces with precision measuring instruments, and supporting workpieces during layout or inspection operations. Its compact 3-inch length makes it practical for benchtop and machine table use where space is limited.

Key Features

• 3-degree angle ground into the block for accurate angular reference work
• 55 HRC hardness for wear resistance and long service life
• 20 arc second accuracy for close-tolerance inspection and setup
• 3-inch overall length suits surface plate and machine table use
• Compact single-piece design with no moving parts to maintain or adjust

Compatibility

Designed as a standard precision angle block for use with surface plates, sine bars, and inspection fixtures in general machining and toolroom applications.

Installation Notes

Angle blocks are used by machinists and quality control technicians and require no permanent installation. Clean mating surfaces before use to remove chips, oil, or debris that could affect angular accuracy. Handle hardened tooling blocks with care to avoid nicking ground surfaces, as surface damage will compromise measurement accuracy. Store on a protected surface or in a case when not in use to preserve the ground faces.
