Starrett 248D Drive Pin Punch 5/16 in 8 in hand tool

Drive Pin Punch 5/16 in Tip

The Starrett 248D is a drive pin punch built for technicians and tradespeople who need to remove or install pins in metal, plastic or wood assemblies. Its 8 in overall length provides reach into recessed holes while the knurled round shank gives a secure grip during striking. The tip diameter is slightly less than the listed 5/16 in to ensure a proper fit without binding.

Upgrade from worn or undersized punches

A punch with a mushroomed tip or a loose fit can damage the surrounding workpiece or fail to move a stubborn pin. The heat-treated construction on this tool resists deformation under repeated blows, so the jump is worthwhile when existing punches no longer hold their diameter or when a precise 5/16 in size is required for the job at hand.

Consistent performance under sustained use

Heat treatment maintains hardness across long sessions of driving pins, preventing the tip from peening over or the shank from bending. The clearly marked diameter on the head allows quick identification without calipers, and the absence of a striking cap means the full length transfers each hammer blow directly to the pin.
