Value Collection MVB/4P V-block Set Magnetic Matched Pair

Product Description

The VALUE COLLECTION MVB/4P is a matched pair of magnetic V-blocks designed for holding and inspecting cylindrical workpieces in machining and metrology applications. Each block features a 90-degree V angle and accommodates round stock from 3/16 inch minimum up to 2-3/4 inches maximum capacity. Constructed from steel with an integrated magnetic chuck, these V-blocks hold workpieces securely without additional clamping hardware. The set is sold as a matched pair, making it suitable for supporting long shafts or round parts at two contact points simultaneously.

These V-blocks are used in tool rooms, machine shops, and quality control environments for layout, grinding setups, and inspection tasks. The magnetic chuck feature allows the blocks to be anchored to ferrous surface plates or machine tables, keeping them positioned during precision work. The matched pair configuration is standard practice when checking roundness, runout, or performing cylindrical grinding on longer stock.

Key Features

• 90-degree V angle for standard cylindrical workpiece support
• Maximum V capacity of 2-3/4 inches; minimum capacity of 3/16 inch
• Steel construction for rigidity and durability under repeated use
• Integrated magnetic chuck secures blocks to ferrous surfaces
• Sold as a matched pair for two-point workpiece support
• Overall dimensions: 4 inches long, 3 inches wide, 3-3/4 inches tall

Compatibility

Designed as a general-purpose matched V-block pair suitable for use on ferrous surface plates, magnetic chuck tables, and similar setups in machine shop and inspection environments where cylindrical workpieces up to 2-3/4 inches diameter require secure support.

Installation Notes

V-blocks are typically set up by machinists or metrology technicians on a clean, flat ferrous surface plate. Ensure the surface plate and V-block bases are free of burrs, chips, and debris before placement to maintain accurate seating. Engage the magnetic chuck according to the block design before loading the workpiece. Demagnetize workpieces after inspection or grinding operations as needed to prevent chip attraction during subsequent machining.
