Starrett 50614 Pin Vise Set 0.187 in 4 Piece

Product Description

The STARRETT 50614 is a 4-piece pin vise set designed for holding small-diameter round stock, drill bits, reamers, and similar tools during precision hand operations. Each vise in the set uses a special tapered collet that maximizes clamping surface contact, reducing slippage on delicate workpieces. The set handles stock up to 0.187 inches (4.80 mm) in diameter, covering a broad range of small-bore applications. Handles are insulated for added safety during use near electrical components. The complete set stores in an included vinyl pouch, keeping all four pieces organized and protected on the job site or in the shop. Machinists, toolmakers, electricians, and maintenance technicians are the primary users.

This pin vise set suits bench work, layout, and light-duty drilling tasks where a standard drill chuck is too large or impractical. Common applications include starting small holes, hand-reaming, holding wire for bending or stripping, and manipulating fine components during assembly or repair. The insulated handles make the set appropriate for low-voltage electrical work where incidental contact with energized conductors is a concern. The 4-piece configuration provides multiple collet sizes within the 0 to 0.187 inch capacity range, allowing the technician to match the collet closely to the workpiece diameter for the best grip.

Key Features

• Suitable for drill bits, reamers, wire, and other small-diameter tooling

Compatibility

Designed as a general-purpose pin vise set compatible with round stock, drill bits, and tool shanks up to 0.187 inches in diameter across maintenance, electrical, and precision machining applications.

Installation Notes

No power source or dedicated installation is required for this hand tool set. Before use near energized circuits, verify that insulation is intact and undamaged. Select the collet that most closely matches the workpiece diameter and tighten firmly before applying rotational force to avoid slipping. Store in the provided vinyl pouch when not in use to protect collet threads and seating surfaces.
