Pin punch for pin removal
The Mayhew 21500 is a hand-held pin punch designed for driving and removing pins in automotive and mechanical work. Its 1/8 in tip suits small pin diameters commonly found in brake, suspension and linkage assemblies. The tool is sold new and meets or exceeds ASME standards for professional use. It targets technicians and DIYers who need a dedicated pin-driving tool.
Heat noise and power draw
As a non-powered hand tool the punch generates no heat, noise or electrical draw during operation. The black oxide finish resists corrosion without requiring lubrication or external energy input. Users rely solely on hammer strikes so physical effort determines the work rate. There are no thermal or acoustic factors to manage in normal use.
One-piece steel build and tether point
The punch uses a one-piece steel construction with a 5/16 in hex body that resists bending under repeated impact. A black oxide coating adds surface hardness and reduces glare under shop lighting. A tether-capable feature allows attachment to a lanyard for drop prevention when working at height. The single-piece design eliminates loose heads or handle separation over time.

Questions about this item
How do I correctly align the 1/8 in tip on the pin so it does not slip off?
Hold the 5/16 in hex body steady and centre the 1/8 in tip on the pin before striking; the common error is tilting the punch, which causes the tip to skate.
What wear should I expect on the black oxide finish and tip over time?
The black oxide will gradually wear to bare steel at the tip and striking end; re-sharpen the 1/8 in tip with a fine file when it mushrooms.
At what point does the 8 in length become a limitation during repeated heavy blows?
The slender 8 in shaft flexes under sustained high-impact use, reducing driving force and increasing the chance of bending.
