Toolroom Use V Blocks Precision Vee Blocks for Design Processing Clamping & Runout Checking Work
Description:
V-Blocks are professional work holding fixtures that enable operators to securely locate and clamp workpieces for machining and inspection operations. The base, side faces and V contact surfaces are fully precision ground, offering stable, reliable and repeatable reference planes to guarantee consistent machining and measuring results.
To maintain long-term accuracy, V-Blocks require periodic inspection. Our V blocks are fully heat treated and precision machined, ensuring stable performance as dependable workshop holding tools.
The signature V-shaped dual contact surfaces firmly support components including round bar, tubular goods and shaft parts. Workpieces rest evenly against both faces of the V profile, which evenly distributes clamping pressure. This uniform force distribution locks the workpiece in a fixed position for precise milling, grinding, layout marking and runout testing.
Each matched-pair V Block is constructed from premium-grade steel, hardened to HRC 55–62 for superior wear resistance. Featuring a standard 90° V-angle and supplied with matching clamping brackets, our metric and inch specification V-blocks achieve high accuracy up to 0.005 mm (0.0002 inch).

long-term heavy workshop usage.
4.Supplied as Matched Pairs with Clamps
Complete set includes paired V-blocks and matching clamping brackets. Metric and inch dimension specifications
cover a wide range of workpiece sizes.
5.Wide Application for Precision Metrology
Perfect work holding fixture for shaft runout testing, petroleum tubing inspection, layout marking, grinding, milling and
quality control in machinery & metrology labs.
Applications:
Q1: What kinds of workpieces can be clamped on these V‑blocks?
A: Perfect for round bar stock, tubular goods and various shaft parts. Workpieces sit evenly against both V‑faces, clamping force is well distributed without workpiece shifting.
Q2: Do V‑blocks need regular maintenance?
A: To keep long‑term accuracy, periodic inspection is required. Keep contact surfaces clean, avoid heavy impact and scratches on ground reference faces. Proper maintenance will extend service life.
Q3: What is the difference between matched‑pair V‑blocks and single V‑block?
A: Matched‑pair V‑blocks are machined as a set to ensure parallelism and height consistency. When supporting long shafts or tubular parts, paired units maintain stable coaxiality; single V‑block cannot satisfy such measuring and clamping demands.
