Forget the direction of your plates. Place it on any direction and grind your piece in either V. Steel used in all the V-blocks and parallels is selected for the highest magnetic transfer and low retention of magnetic flux. Cast integrally with aluminum to insure the blocks will never crack or become loosened even when accidentally dropped.
- Precision ground
- Integrally cast into one solid piece

Precision Blocks are extremely useful in mounting work for precision grinding, machining, layout or inspection. Blocks are precision ground on all six sides to a smooth and accurate finish. Holes are not drilled in order to eliminate the trapping of dust and dirt. The corners are not chamfered to push particle out of the way on your surface plate. These precision blocks are sold singly and measure 1" x2" x3" within ± .0001", making .0002" the maximum possible error exist between two blocks.
- Quality steel hardened to Rc 58-60
- Square and parallel within .0002"
- One Piece Precision 1-2-3 Block- no holes
