Starrett 63323 Magnetic V-block 1-3/4 in 90 Degree

Product Description

The STARRETT 63323 is a dual-vee magnetic V-block used to hold and position cylindrical workpieces during layout, inspection, and machining operations. Built from hardened steel, it accepts round stock from 1/4 inch minimum up to 1-3/4 inch maximum diameter and features a 90-degree V angle for stable, repeatable seating. The integrated magnetic base holds the block securely to ferrous surfaces without clamps. At 5.2 pounds, this is a solid, professional-grade toolroom accessory suited for machinists, metrology technicians, and precision tradespeople who need consistent part positioning during measurement or light grinding setups.

The 63323 is used in toolroom, machine shop, and inspection environments where accurate cylindrical workpiece support is required. The magnetic feature makes it practical for surface plate work and magnetic chuck applications. It is sold as an individual unit and is well suited for use on surface plates, milling machine tables, and inspection fixtures where a 90-degree reference angle and firm magnetic hold are required.

Key Features

• 90-degree V angle provides stable, centered seating for round stock
• Accepts workpieces from 1/4 inch to 1-3/4 inch diameter
• Hardened steel construction for wear resistance and dimensional stability
• Integrated magnetic base secures block to ferrous surfaces without additional clamps
• Dual-vee design increases versatility across workpiece size ranges
• Compact overall dimensions suit surface plate and fixture use

Compatibility

Designed as an OEM-style precision toolroom accessory compatible with standard surface plates, magnetic chucks, and milling machine tables where a hardened steel V-block with magnetic base is required.

Installation Notes

Installation and use of V-blocks typically falls to machinists or metrology technicians working in tool and inspection rooms. Before positioning a workpiece, ensure the mating surface is clean and free of chips or burrs that could affect seating accuracy. When used on a magnetic chuck or ferrous surface plate, verify the magnetic hold is fully engaged before applying any clamping or measuring force. Do not use the magnetic base on non-ferrous surfaces, as holding force will not be achieved.
