Starrett 50609 Pin Vise 0.040 Inch Collet Jaw

Product Description

The STARRETT 50609 is a pin vise designed for holding small-diameter round stock, wire, drills, and pins during precision hand work. It features a collet-style jaw with a special tapered collet that maximizes clamping surface contact, giving the user a secure grip on workpieces up to 0.040 inches (1.0 mm) in diameter. The octagon-shaped handle provides positive grip and prevents the tool from rolling on a bench surface. The handle body measures 0.5 inches in diameter. This tool is commonly used by machinists, instrument technicians, electricians, and trade professionals who work with small wire gauges, drill bits, or needle files requiring precise manual rotation.

The STARRETT 50609 is suited for bench work, field service, and precision layout tasks where a standard drill chuck or vise is too large for the workpiece. Typical applications include holding small twist drills for hand reaming, gripping thin wire for routing or bending, and securing small taps or reamers during close-tolerance work. The insulated construction adds a layer of safety when working near energized circuits or sensitive electronic assemblies. This vise is appropriate for individual use in maintenance, electrical, and instrumentation trades.

Key Features

• Collet-style jaw with special tapered collet for maximum clamping surface on small stock
• Capacity up to 0.040 inches (1.0 mm) diameter workpieces
• Octagon handle shape prevents bench rolling and improves grip control
• Insulated construction for added safety near sensitive or energized components
• Compact 0.5-inch body diameter suited for tight-clearance bench work

Compatibility

Designed as a general-purpose pin vise for use with small-diameter drill bits, wire, pins, and round stock up to 0.040 inches in diameter across a range of precision hand-tool applications.

Installation Notes

Pin vises require no installation. When using near electrical panels or energized conductors, verify the insulation rating is appropriate for the voltage present before contact. Keep jaws clean and free of debris to maintain consistent clamping force on small-diameter stock. Avoid exceeding the rated capacity of 0.040 inches to prevent collet damage or workpiece slippage.
