Hougen Mfg. has upgraded its 14,000-series Holcutters, which cut holes in sheetmetal of up to ¹ /8-in. thick, to include a single arbor size for all cutting diameters, a four-lead thread for fast spin-on attachment of arbor and cutter, and an outside shoulder on the cutter, which prevents it from plunging through the completed hole.
