The Mittler Bros. 13-Piece AC-35 Aircraft Punch & Flare Set covers the most common panel hole sizes from 1″ through 4″ — punching a clean hole and adding a low-profile 35° aircraft flare in a single step for improved strength and appearance. Simply drill a small pilot hole for the draw bolt, apply the tool, and tighten. No need to pre-drill the full hole size — the punch and aircraft-style flare happen simultaneously.
Use it in the Mittler Bros. Bench/Louver Press (sold separately) for fast production work, or use with just a wrench on the supplied bolt for a quick one-off job. Rated for .020″–.040″ aluminum and mild steel. Precision machined from heat-treated steel for years of use. Made in the USA.
