Brass Drive Pin Punch for Delicate Assembly

The Starrett B248D is a hand-held punch designed for driving pins without marring softer workpieces. Its brass construction prevents damage to metal, plastic and wood surfaces during assembly or maintenance tasks. The 8 in overall length provides reach for recessed fasteners. Machinists and technicians who need non-marring impact choose this tool for precise alignment work.

Knurled Grip and Marked Diameter Improve Control

A knurled round shank gives a secure hold even with oily hands. The punch diameter is clearly stamped on the head so the correct size is identified at a glance. No striking cap or handguard is included, keeping the profile slim for tight access. The flat tip delivers direct force to pin ends without slipping off centre.

Brass Build Resists Sparking and Deformation

Brass material will not damage softer materials and reduces spark risk in sensitive environments. The round shank fits standard punch holders and the 5/16 in tip matches common pin diameters. Diameter of punches is slightly less than listed, ensuring a free fit in holes. The tool ships in a simple box ready for the bench or tool roll.

Questions about this item

Will the brass tip on this B248D punch need replacing after heavy use?

The brass tip is softer than steel and will mushroom or wear down over repeated strikes, so it will eventually need replacement.

What stops me from driving this 8 in punch deeper into a workpiece?

The 5/16 in tip diameter and 8 in overall length set the practical depth limit before the shank contacts the surface.

Does the brass construction keep the punch cooler during extended driving sessions?

Brass conducts heat well, so the punch body warms quickly with sustained hammer blows, but it will not spark or damage softer materials.
