MAYHEW PRO

Mayhew Pro punches and chisels are forged from high-carbon steel, which provides the hardness and toughness required for striking and cutting applications. The tools are heat-treated to achieve a balance of strength and durability. For example, the diamond-point chisel (MPN 10604) is designed for cutting or shaping metal, concrete, and masonry. The steel construction allows the tools to withstand repeated hammer strikes without premature deformation. Some sets, such as the combination punch set (MPN 62277), feature non-sparking construction for use in environments where flammable vapors or dust may be present. The specific steel grade and heat treatment are not published in the catalog, but the tools meet ASME B107.410-2008 for chisels and related standards for punches.

A prick punch, such as the Mayhew Pro 6-inch prick punch (MPN 23003) with a 1/8-inch tip, is used to create small indentations in metal as a starting point for drilling or layout marking. It has a tapered point that allows for precise marking. A solid punch, like the 1/4-inch solid punch included in the combination punch set (MPN 62277), is typically used for driving out pins or aligning holes. Solid punches have a flat or slightly rounded tip and are designed for direct impact. Both types are available in various sizes and lengths. The prick punch has a hexagon, plain grip design for better control, while solid punches may have a similar grip. The choice depends on the task: marking versus driving.

Yes, Mayhew Pro offers gasket punch sets in both SAE and metric sizes. For example, the 11-piece metric hollow punch set (MPN 66010) includes metric hollow punches for cutting clean holes in light sheet metal and gasket materials. The set comes in a case and includes a 4 mm punch size. SAE sets are also available, such as the 10-piece SAE hollow punch set (MPN 66012) with a 5/16-inch punch, and the 11-piece SAE set (MPN 66008) with a 3/8-inch punch. The 31-piece set (MPN 66006) includes a range of SAE sizes from 5/8 inch to 2 3/8 inch. These sets are used for cutting gaskets from sheet material, with hollow-ground punches for precise, burr-free holes.

The non-sparking feature in the Mayhew Pro combination punch set (MPN 62277) is designed for use in environments where flammable vapors, gases, or dust may be present. Standard steel tools can produce sparks when struck against hard surfaces, which could ignite combustible materials. Non-sparking tools are typically made from materials such as beryllium copper or aluminum bronze, which reduce the risk of sparking. This set includes a 1/4-inch solid punch and a pin punch with overall lengths of 4 inches and 6 inches, supplied in a bag. It is suitable for maintenance tasks in petrochemical, mining, or other hazardous industries where spark prevention is critical. The set is not intended for high-impact striking in the same way as standard steel punches.

The Mayhew Pro 31-piece gasket punch set (MPN 66006) includes hollow punches in sizes 1 inch, 5/8 inch, 2 1/4 inches, 1 3/8 inches, 1 7/8 inches, 2 1/8 inches, and 2 3/8 inches. Each punch has an overall length of 46 mm. The set is supplied in a vinyl case for storage and organization. This range of sizes allows for cutting various gasket diameters from sheet material. The punches are hollow-ground to produce clean, burr-free holes in gaskets and light sheet metal. The set is part of the Mayhew Pro line of gasket punch sets, which also includes SAE and metric configurations in smaller piece counts. The 31-piece set is suitable for maintenance operations that require a broad selection of punch sizes.
