Product overview

The JXHONG Upgraded Broad Head Bull Pin Alignment Punches combine precision with durability for workshop tasks that involve guiding and seating pins. The cone range runs from 1-1/4 inches to 5/16 inch, and the assembly is 13.75 inches long, offering a balanced reach for both shallow and deeper holes. Crafted from heat-treated AISI 4135 alloy steel, this tool is built to hold its edge and shape through repeated use.

Thoughtful design for real-world work

The mushroom-shaped broad head is paired with a galvanised surface to reduce sticking and corrosion in damp environments. The tool feels substantial in hand, with a weight around 2.63 lbs that provides confidence without sacrificing control. A flat surface is machined for compatibility with a spanner, helping you loosen wedged pins more smoothly. A 1/4 inch tether hole lets you pass a small tether or hook, keeping the tool accessible during busy jobs.
