Select a product to estimate shipping.This ultra-precision 1 2 3 block pair comes with 5 pieces of 3/8"-16 socket head cap screws, 1 pair of 23-hole 1-2-3 blocks, and 1 hex key. The 23-hole feature provides more configuration than the other 1-2-3 blocks. The cap screws and the hex key saves you time on the setup of the machines. The 0.0001"/1" squareness, ±0.0001" height accuracy in pair, and ±0.0001" parallelism can give you much more accurate results. The 1-2-3 blocks are for both metalworking and woodworking. Everyone will love it as it is affordable, versatile, and convenient.

Mill Setup Tools
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.
Count of holes of Accusize Precision Blocks
The holes on the precision blocks enable them to be bolt together into different configurations. So the more holes a block has, the more configurations the pair of the blocks can create.
The precision blocks with fewer holes or without holes have advantages. During the milling application, the craps, chips, abrasives from the wheel, coolant, etc., could enter the blocks' holes. It lowers the total productivity of the work. The concerns can be solved by using the blocks with fewer holes or even no holes.
The following are the all Accusize Precision Blocks:
