Value Collection VB/T/45 V-block Set 1 in 90 Degree

Product Description

The VALUE COLLECTION VB/T/45 is a matched 2-block V-block set machined from tool steel and hardened to 55-60 HRC for precision workholding applications. Each block features a 90-degree V angle and accepts round stock from 9/16 inch minimum up to 1 inch maximum capacity. Overall dimensions are 1-3/4 inches long, 1-19/32 inches wide, and 1-7/16 inches tall. The set ships with two clamps and is suited for inspection, layout, drilling, and grinding setups where accurate and repeatable part positioning is required.

This V-block set is intended for use in machine shops, tool rooms, and precision inspection environments. The hardened tool steel construction and tight parallelism tolerance of 0.0003 inch make it appropriate for both production and quality-control workflows. Machinists, toolmakers, and metrology technicians typically use sets like this on surface plates, milling machine tables, and drill press fixtures to hold cylindrical workpieces during machining or measurement operations.

Key Features

• 90-degree V angle with 9/16 inch minimum and 1 inch maximum round-stock capacity
• Tool steel construction hardened to 55-60 HRC for wear resistance and dimensional stability
• V parallelism of 0.0003 inch (8 micrometers) for repeatable, accurate workholding
• Squareness tolerance of 0.0003 inch per inch for precise angular alignment
• Large V width of 1-1/8 inch provides stable seating across the capacity range
• Includes two clamps to secure workpieces without additional hardware
• Sold as a matched 2-block set for shaft alignment and through-bore applications

Compatibility

Designed as a general-purpose precision V-block set compatible with standard surface plate and machine table workholding setups where a 90-degree V angle and up to 1 inch round-stock capacity are required.

Installation Notes

V-blocks should be placed on a clean, burr-free surface plate or machine table before securing the workpiece with the included clamps. Inspect mating surfaces for nicks or debris prior to use, as contamination will affect parallelism and squareness readings. Clamp fasteners should be snugged evenly to avoid distorting the workpiece or rocking the block. Always verify block seating and workpiece runout with an indicator before committing to a machining or inspection operation.
