Value Collection 420-5616 V-block 2-1/4 in 90 Degree

Product Description

The VALUE COLLECTION 420-5616 is a hardened steel V-block designed for precision workholding in machining, inspection, and layout operations. It features a 90-degree V angle with a maximum capacity of 2-1/4 inches, making it suitable for securing round stock, shafts, and cylindrical workpieces during drilling, grinding, or measurement tasks. The block measures 4 inches in overall length, 3 inches in overall width, and 3 inches in overall height. A clamp is included. V parallelism and squareness are both held to 0.0002 inches, reflecting the tight tolerances expected in precision toolroom and metalworking applications. Machinists and toolmakers are the primary installers and users of this accessory.

This V-block is suited for use on surface plates, milling machine tables, drill press tables, and inspection benches. It is sold as an individual unit and is appropriate for both job shop and production environments where repeatable, accurate workholding of cylindrical parts is required. The 90-degree angle accommodates a wide range of round stock diameters up to 2-1/4 inches. The included clamp helps secure the workpiece during machining or layout without additional fixturing hardware.

Key Features

• Hardened steel construction for wear resistance and long-term dimensional stability
• 90-degree V angle accepts cylindrical workpieces up to 2-1/4 inches in diameter
• V parallelism held to 0.0002 inches for precise, repeatable positioning
• Squareness tolerance of 0.0002 inches supports accurate layout and inspection work
• Clamp included for positive workpiece retention without additional hardware
• Non-magnetic construction avoids interference with sensitive measuring instruments

Compatibility

Designed as a general-purpose precision V-block for use with standard surface plates, milling tables, and drill press setups that accommodate a block measuring 4 inches long, 3 inches wide, and 3 inches high.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician familiar with workholding practices. Ensure the mating surface is clean and free of chips or burrs before seating the V-block to maintain accuracy. Secure the included clamp firmly before beginning any machining or grinding operation. Periodically verify parallelism and squareness against a known reference if the block is used in high-cycle production environments.
