Starrett 50604 Pin Vise Set 0.187 in 4 Piece

Product Description

The STARRETT 50604 is a 4-piece pin vise set designed for holding small-diameter round stock, drill bits, reamers, and wire during precision hand work. Each vise features a special tapered collet that provides maximum clamping surface across the capacity range, reducing slippage and improving control. The set handles stock up to 0.187 inches (4.80 mm) and is suited for machinists, toolmakers, electricians, and maintenance technicians who need repeatable grip on small workpieces. The complete set ships in a vinyl pouch that keeps all four vises organized and protected on the job or in a toolbox.

This set is a practical addition to any precision hand-tool kit used in light manufacturing, instrumentation work, electrical panel assembly, or general maintenance. The range of four vises covers different collet sizes within the 0 to 4.80 mm capacity, allowing the technician to select the correct chuck for the workpiece without re-adjusting a single tool. Typical applications include starting small taps, holding carbide scribers, and spinning small drill bits by hand in confined spaces where a powered drill is impractical.

Key Features

• 4-piece set covers 0 to 0.187 inches (0 to 4.80 mm) capacity range
• Special tapered collet design maximizes clamping surface for secure grip
• Compact 4-inch handle length for controlled hand rotation in tight areas
• Includes vinyl pouch for organized storage and transport
• Suitable for drill bits, reamers, wire, and small-diameter round stock

Compatibility

Designed as a general-purpose precision hand tool compatible with any round workpiece or shank up to 0.187 inches (4.80 mm) in diameter, including standard wire gauges and small-diameter drill bits used across machining, electrical, and maintenance trades.

Installation Notes

No power source or mounting hardware is required for use. Inspect collet threads and tapered seating surfaces before use and keep them free of chips and debris for consistent clamping. Apply only hand-level torque when tightening the collet cap to avoid deforming the tapered collet. Store the set in the included vinyl pouch to protect collet surfaces from contamination.
