Precision Brand 40045 Shim Replacement Punch A2 Tool Steel

Product Description

The PRECISION BRAND 40045 is an A2 tool steel shim replacement punch designed for precision hole punching in shim stock and thin sheet materials. With a 0.5 inch diameter and a 2 inch overall length, this punch delivers clean, accurate cutouts for shim applications in mechanical assembly, maintenance, and alignment work. A2 tool steel provides a balance of toughness and wear resistance, making it suitable for repeated use in production and field service environments. Machinists, millwrights, and maintenance technicians typically keep this tool in their precision layout and fitting kits.

This punch is suited for use in industrial, commercial, and manufacturing settings where custom shim fitting is required. Common applications include machinery alignment, equipment mounting, and bearing or gear clearance adjustment. The 0.5 inch punch diameter covers one of the most frequently needed sizes for standard shim stock perforation, making it a practical addition to any shim toolkit used in plant maintenance or precision assembly operations.

Key Features

• A2 tool steel construction for durability and wear resistance under repeated impact
• 0.5 inch diameter for consistent, clean holes in shim stock
• 2 inch overall length provides adequate hand clearance during use

Installation Notes

This punch is driven with a hammer or mallet against shim stock placed on a firm backing surface such as a steel block or end-grain hardwood. Always wear appropriate eye protection when using punches. Inspect the punch tip for deformation or chipping before each use and replace if the tip shows signs of cracking or mushrooming on the strike end.
