Precision Block Sets, metric and inch

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.
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.

We are expanding the product line of Accusize precision blocks. We provide 1-2-3 blocks with no-holes, 1-hole, 11-hole, and 23-hole; we carry 2-3-4 blocks and 2-4-6 blocks with 23-hole. In the future, we are bringing more and more options. Choose the blocks based on your milling jobs.
