112-Piece Metric Gage Block Set: Block Sizes and Stack Examples

Gage block stacks โ€บ 112-piece metric set

The 112-piece metric set extends the 0.5 mm series up to 24.5 mm and adds 25, 50, 75 and 100 mm blocks, so mid-size stacks can use fewer blocks than with the 88-piece set.

The block list below is the composition the free gage block calculator uses for this set. Sets from different makers can differ slightly, so check the sizes marked on the blocks in your own box.

Total: 112 blocks, smallest 0.5 mm, largest 100 mm. All blocks laid end to end would measure 933.7955 mm.

What sizes can it build?

Each block can be used once in a stack. Working it out for every size, every size in steps of 0.001 mm from 2.000 to 930.795 mm can be built, as long as the stack uses each block only once.

Worked examples

Fewest-block stacks from the same solver the calculator uses; each one adds up to the target exactly.

If a block is missing or worn

Untick the block in the free gage block calculator and it finds the next-best stack from what is left. If your set includes wear blocks, they can be added to the ends of a stack to protect the working blocks; see gage block care and wear blocks.
