The PRECISION BRAND 40110 is a punch die set designed to cut custom washers, shims, and gaskets quickly and cleanly from sheet material. The set uses a patented punch, pilot, and pin system that guides the cut for consistent, accurate results on every stroke. Technicians working in HVAC, plumbing, and mechanical trades often need non-standard shim or gasket sizes that are not available off the shelf. This set lets the installer produce a finished part on the job in seconds without machining or fabrication equipment. At 2.45 pounds, the set is compact enough to carry in a service bag.
The 40110 is suited for field and shop use wherever a technician needs to fabricate a custom washer, shim, or gasket to match a specific bore or outside diameter. Typical applications include isolation shims for mechanical equipment, custom gaskets for flanged connections, and replacement washers for fastener assemblies in residential and light commercial systems. The punch-and-die design produces clean edges without tearing or deforming the workpiece material.
Designed as a general-purpose punch die set for fabricating custom washers, shims, and gaskets from sheet stock materials across trade service applications.
This tool is operated by hand or with a press and does not require electrical power. Select an appropriate backing material to protect the work surface before punching. Follow the manufacturer instructions for aligning the pilot pin to prevent off-center cuts. Keep fingers clear of the punch path during operation.
