Value Collection 630-0025 Angle Block 0.25 Degree 3 Inch

Product Description

The VALUE COLLECTION 630-0025 is a precision angle block machined to a fixed 0.25-degree angle and measuring 3 inches in overall length. Angle blocks are hardened reference tools used in metrology, inspection, and machining setups to establish or verify precise angular relationships between workpiece surfaces or inspection fixtures. This block is hardened to 56 HRC, providing the surface durability required for repeated use in production and quality-control environments. An accuracy rating of 20 arc seconds makes it suitable for close-tolerance layout and inspection work. Machinists, tool-and-die makers, and quality technicians are the primary users.

This angle block is suited for use in machine shops, tool rooms, and inspection departments where small, precise angular offsets are needed for setups, sine plate work, or surface plate inspection routines. Its compact 3-inch length fits standard setups without overhanging critical reference surfaces. The 0.25-degree angle addresses fine-offset applications common in precision grinding and milling fixture work.

Key Features

• Fixed 0.25-degree angle for consistent, repeatable angular reference
• 3-inch overall length fits standard machine and inspection setups
• 56 HRC hardness resists wear and surface deformation with regular use
• 20 arc-second accuracy rating supports close-tolerance inspection and layout
• Single-piece solid construction with no moving parts to drift or loosen

Compatibility

Designed as a general-purpose precision angle block for use on surface plates, sine plates, and magnetic chucks in standard metrology and machining fixture applications.

Installation Notes

Angle blocks are positioned and used by machinists or quality technicians — no power source or licensed trade certification is required for typical use. Clean the reference surfaces of both the block and the mating surface plate or fixture before each use to prevent burrs or debris from introducing angular error. Do not drop or impact the block against hard surfaces, as shock can alter hardness characteristics or introduce surface damage that degrades accuracy. Store in a protective case or on a padded surface when not in use.
