The Mittler Bros. 3-3/8″ Gauge Hole Punch creates a clean, precise hole for standard automotive instrument gauges in one easy step. Just drill a small pilot hole for the draw bolt, apply the tool, and tighten — the result is a perfectly round, properly sized hole ready for your gauge to drop right in.
Use it with a Mittler Bros. Bench Press for fast production work, or simply tighten the supplied bolt with a common wrench or ratchet for a quick one-off install. Bench/Louver Press sold separately. The 3-3/8″ is the largest size in the lineup, used for bigger gauge clusters and speedometer-style instruments. Made in the USA.
