InSize 6889-1 Magnetic V-Blocks 3.0x2.2x3.0 Inch Pair

The InSize 6889-1 Magnetic V-Blocks are a matched pair of precision magnetic V-blocks designed for workholding, inspection, and layout tasks in machine shops, toolrooms, and metrology environments. Each block measures 3.0" x 2.2" x 3.0", providing a stable and versatile platform for holding cylindrical workpieces securely during grinding, milling, drilling, or inspection operations.

These V-blocks feature built-in magnetic bases that allow them to clamp firmly to ferrous surfaces such as surface plates, machine tables, and magnetic chucks — keeping both the block and the workpiece firmly in position without the need for additional clamps or fixtures.

Key Features:

• Matched Pair: Supplied as a matched pair for supporting long shafts, rods, or cylindrical parts at two points
• Magnetic Base: Integrated magnets hold the V-blocks securely to ferrous surfaces for hands-free workholding
• V-Groove Design: Precision-machined V-groove accurately centers and supports round or cylindrical workpieces
• Dimensions: Each block measures 3.0" (L) x 2.2" (W) x 3.0" (H)
• Hardened Steel Construction: Ground and hardened steel surfaces for long-term wear resistance and dimensional stability
• Versatile Application: Suitable for inspection, layout, grinding setups, and general machining support tasks

InSize is a globally recognized manufacturer of precision measurement and inspection tools. The 6889-1 magnetic V-block pair is a reliable addition to any toolroom or quality control department, combining the convenience of magnetic holding with the accuracy demanded by professional machinists and metrologists.
