Mitutoyo 985-119 Pin Punch Set 8 Piece Drive Style

Product Description

The MITUTOYO 985-119 is an 8-piece drive-style pin punch set covering a size range of 0.0625 to 0.3125 inches. Each punch features a round shank and measures 4 inches in overall length. The set ships stored in a plastic sleeve, keeping the punches organized and ready for jobsite use. Pin punch sets of this type are used to drive pins, rivets, and roll pins from bores and assemblies without damaging the surrounding material. Licensed machinists, millwrights, maintenance technicians, and tool-and-die professionals reach for a set like this during disassembly and reassembly tasks on machinery, equipment housings, and mechanical linkages.

This set is suited for use in maintenance, repair, and overhaul (MRO) environments across industrial, commercial, and light manufacturing settings. The eight included sizes provide coverage for the most commonly encountered pin diameters in mechanical assemblies. Sizes included are 0.0625 inches, 0.09375 inches, 0.125 inches, 0.15625 inches, 0.1875 inches, 0.21875 inches, 0.25 inches, and 0.3125 inches. The drive style makes these punches compatible with a standard ball-peen hammer or mallet for controlled impact work.

Key Features

• 8-piece set covers 0.0625 to 0.3125 inches in eight incremental sizes

Compatibility

Designed as a general-purpose pin punch set for use with standard roll pins, dowel pins, and drive pins found in mechanical assemblies across industrial and maintenance applications.

Installation Notes

Pin punch work is typically performed by machinists, millwrights, or maintenance technicians. Secure the workpiece in a vise or fixture before driving pins to prevent movement and avoid injury. Always use a ball-peen hammer or brass mallet rated for impact tooling — substituting improper strike tools can damage punch faces or create uncontrolled ricochets. Inspect punch tips before each use and replace any punch showing mushrooming, cracking, or deformation.
