Value Collection 630-4315 Angle Block 15 Degree 3 Inch

Product Description

The VALUE COLLECTION 630-4315 is a 15-degree angle block used for precision setup work in machining and inspection applications. The block is 3 inches long and ground to 55 HRC hardness, which provides durability and resistance to wear during repeated use. Accuracy is rated to 20 arc seconds, making this block suitable for tight-tolerance setups. Machinists, toolroom technicians, and quality control personnel use angle blocks to establish precise angular reference surfaces when grinding, milling, or inspecting workpieces.

This angle block is sized for benchtop and surface plate use in toolrooms, job shops, and manufacturing environments. The 15-degree angle covers a common setup requirement for chamfered parts, angled surfaces, and compound fixtures. Its compact 3-inch length fits standard vises and magnetic chucks without overhang issues. The hardened steel construction holds its geometry under clamping loads and normal shop-floor conditions.

Key Features

• 15-degree fixed angle for repeatable angular setups
• 55 HRC hardness resists wear and maintains accuracy over time
• 20 arc-second accuracy for tight-tolerance machining and inspection
• 3-inch overall length suits most benchtop and surface plate applications
• Compact single-piece construction with no moving parts to go out of adjustment

Compatibility

Designed as a general-purpose angle block for use with surface plates, sine bars, magnetic chucks, and milling vises in standard toolroom and machining setups.

Installation Notes

Angle blocks are set up by toolroom machinists and quality technicians — no power tools or trade licenses are required. Clean the reference surfaces of both the angle block and the workholding device before use to remove chips, oil, and debris that could affect angular accuracy. Do not use the block as a striking surface or clamp against it with excessive force, as this can alter ground surfaces.
