Description
Product Overview
The Taytools 770788 1-2-3 Blocks V‑Block pair is a precision‑engineered solution for dimensional calibration, inspection, and machining setups. Constructed from hardened tool steel with a Rockwell hardness of RC 56‑60, each block undergoes meticulous precision grinding on all six faces, guaranteeing flatness and parallelism within ±0.0001″. This extreme tolerance ensures that the blocks provide a stable, true reference surface for a wide range of industrial applications.
Both blocks are matched to each other with a tolerance of 0.0002″, meaning that when used together they maintain consistent geometry, reducing cumulative error in multi‑block assemblies. The overall dimensions of each block are controlled to within ±0.0001″ and the squareness of each face is held to within ±0.0003″ per inch, delivering the kind of repeatable accuracy demanded by high‑precision environments.
Usage
These V‑Blocks are ideal for securing workpieces, fixtures, and tooling components during machining, grinding, and inspection processes. The eleven 5/16″‑18 tapped holes—strategically placed on the 2″ × 3″ and 1″ × 2″ faces—allow users to bolt the blocks directly to a workbench, a jig, or to each other, creating custom angle plates or converting the pair into a stable base for complex setups.
Typical applications include:
- Mounting cylindrical parts for turning or grinding operations.
- Creating reference planes for coordinate measuring machines (CMMs).
- Building custom fixtures for aerospace component inspection.
- Forming angle plates for precision layout work.
- Supporting workpieces in metrology labs where sub‑micron accuracy is required.
The blocks’ robust construction and matched tolerance make them suitable for both high‑volume production environments and low‑volume, high‑precision prototyping labs.
Why Choose Us
Choosing the Taytools 770788 V‑Block pair means investing in a product that combines material excellence with meticulous manufacturing. Hardened tool steel provides superior wear resistance, ensuring the blocks retain their geometry even after repeated use and exposure to coolant or abrasive environments.

FAQ
What is the advantage of hardened steel (RC 56‑60) for V‑Blocks?
Hardened steel offers superior wear resistance and maintains dimensional stability under temperature changes and mechanical stress, ensuring the V‑Block remains accurate over many years of use.
How do I install the V‑Blocks on my workbench?
Use the eleven 5/16″‑18 tapped holes to bolt the blocks directly to a flat surface or to each other. This creates a rigid, stable platform that can be customized for a variety of fixture configurations.
Can the blocks be used as angle plates?
Yes. By fastening the two blocks together at a specific angle using the tapped holes, you can form a precise angle plate suitable for layout and inspection tasks.
What is the recommended maintenance routine?
Periodically clean the block surfaces with a lint‑free cloth and mild solvent to remove debris. Inspect the tapped holes for wear and re‑tap if necessary to maintain secure fastening.
Do you provide calibration certificates?
While the blocks are manufactured to tight tolerances, we can supply a calibration certificate upon request to document the exact dimensions and flatness achieved during production.
