Overview
Five tool steel punches make up the Mayhew 32020 set, finished with a brushed surface and weighing 8 ounces total, sized for driving pins and rivets in metalworking and automotive repair.
Tool steel is a common choice for punches because it holds a point under repeated hammer strikes better than softer metals. A 5-piece set typically spans a small range of tip diameters, letting one set cover several pin or rivet sizes rather than needing separate tools for each. The listing does not break out individual punch diameters, so buyers needing an exact size should confirm before ordering.
- Tool steel construction
- Brushed finish
- 5-piece set
- 8 ounce total weight
Who it's for
Fits mechanics and metalworkers who need a small set of punches for pins, rivets and similar driving tasks. Less useful for anyone needing one specific, confirmed punch diameter, since sizes are not broken out.
Strengths and trade-offs
Drawn from this product's published specifications.
- Tool steel construction resists deforming under repeated strikes
- 5-piece set covers a range of pin sizes
- Light overall at 8 ounces
- Individual punch diameters not listed
- No handle or grip detail given
- No case or storage information provided
Performance notes
Tool steel construction lets these punches hold their point through repeated hammer strikes without deforming as quickly as softer metal would. Being sold as a 5-piece set spreads that durability across a range of tip sizes for different pin and rivet jobs. The brushed finish is mainly cosmetic and does not affect how the punches perform.
