Description

1-2-3 precision blocks are precision ground block at exactly 1 inch by 2 inches by 3 inches. The 2-3-4, 2-4-6, and 25-50-75mm blocks apply the same principle. The blocks are accurately ground, so they are the standard that machinists use in terms of setting up, doing fixturing, touching off tools. They can be used with various milling machines' setup tools such as height gauge and test indicators in inspection for calibration and measuring.
