• CUTS CLEAN, ACCURATE HOLES FROM 2" TO 12" IN 20-GAUGE GALVANIZED STEEL: The HC1 installs into the chuck of any corded or cordless drill with a 1/4-inch or larger chuck and punches precise round holes through 20-gauge galvanized steel, aluminum, copper, and 22-gauge stainless. Adjustable in 1/8-inch increments across the full 2"–12" diameter range. The combination English/metric diameter gauge on the pivot slide takes the guesswork out of setting your diameter.
• "GOLD STANDARD" MILL-TYPE CUTTER BIT WITH PRECISION-FIT SEALED BEARINGS: The distinctive gold bit, bearings, and pivot pin aren't just cosmetic. The mill-type cutting edge wears only in the dimension of the material thickness being cut and not through the full bit. When the active cutting zone dulls, slide the bit up or down along its large flat to expose a fresh edge and keep cutting. Precision-fit sealed bearings deliver smooth, vibration-free rotation at the full rated capacity. Replacement
• LIGHTWEIGHT ALUMINUM FRAME; PORTABLE ENOUGH FOR THE TOOL POUCH, STURDY ENOUGH FOR DAILY USE: The HC1's aluminum frame keeps the tool light without sacrificing rigidity. Fits easily in a tool bag or pouch between jobs with no dedicated case required. Installs into the drill chuck in seconds and stores just as fast. On a job site where you're moving between locations all day, a hole cutter that travels like a hand tool matters.
• CUTS GALVANIZED STEEL, ALUMINUM, COPPER & STAINLESS; ONE TOOL FOR EVERY HVAC HOLE CUTTING APPLICATION: The HC1 handles 20-gauge galvanized steel, aluminum, copper, and 22-gauge stainless steel, covering the materials commonly used in HVAC installation, ductwork fabrication, and sheet metal work. From register openings and collar holes to take-off cutouts and equipment knockout holes, if the job requires a clean, round hole in sheet metal, the HC1 delivers.
• FIELD-SERVICEABLE WITH BITS YOU CAN ALREADY HAVE IN YOUR POUCH: The HC1 and HC2 use the same mill-type cutter bit, sealed bearings, and pivot pin; meaning one set of spares covers both tools. Bits are easily replaceable on the job. The easy-adjusting pivot pin holds its set position through repeated use in heavy-gauge material.
