Mitutoyo 985-143 Pin Vise Set 4 Piece 0.1880 in

Product Description

The MITUTOYO 985-143 is a 4-piece pin vise set designed for holding small-diameter stock, drill bits, wire, and pins during precision hand work. Pin vises are the standard tool for controlled manual drilling, reaming, and light rotation tasks where a power tool would be too aggressive or imprecise. This set accommodates stock up to 0.1880 inches in capacity, covering a practical range of small-diameter work common in instrument repair, metrology, machining, and fine fabrication. The set ships in a vinyl pouch for organized storage. It is used by machinists, instrument technicians, and precision trade professionals who require accurate hand control over fine tooling.

Pin vises in this size range are well-suited for residential and commercial maintenance environments, tool rooms, and precision assembly benches. The 4-piece configuration allows a technician to pre-chuck multiple bits or pins and swap between them without re-chucking mid-task. Typical applications include tapping small holes, holding drill bits for hand drilling in tight spaces, and gripping wire or rod for bending and forming operations. The vinyl pouch keeps the set contained and portable for field or bench use.

Installation Notes

Pin vises are hand tools and do not require mechanical installation. Ensure the collet or chuck is fully tightened before applying rotational force to avoid slipping and damaging the workpiece or bit. When used for hand drilling, secure the workpiece firmly in a vise or fixture before proceeding. Inspect the vise body and chuck mechanism for wear or damage before each use.
