“Gold Standard” Sheet Metal Hole Cutters and Cutter Bits
Malco’s sheet metal hole cutter quickly installs into the chuck of any corded or cordless drill as small as 1/4″ (6.35 mm). The Distinctive Gold Bits, Bearings, and Pivot Pin signify the longest lasting, fastest cutting, and easiest adjusting solution for cutting holes in sheet metal. A Lightweight aluminum frame makes these accessories extremely portable for a variety of hole cutting applications in sheet metal, which includes 20-gauge (1.02 mm) galvanized steel. A compact model HC1 Hole Cutter is adjustable for making 2 to 12″ (51 to 305 mm) diameter holes. The larger HC2 model cuts 2 to 20″ (51 to 508 mm) holes. A combination English/Metric diameter gauge is included on the adjustable pivot slide for both models and both models use the same mill-type Cutter Bit and replacement parts.
Both the HC1 and HC2 sheet metal hole cutter feature Malco’s “Gold Standard” Cutter Bits. These cutter bits feature a long lasting, mill type cutting edge and large flat for adjusting the cutting edge location up or down to extend bit life. The CB cutter bit fits either model and is easily replaceable. These bits are available in 1 pack (#CB), 6 pack (#CBB), as well as a bulk pack of 100 (#CB100).
- Versatile for a variety of metal work.
- Longest lasting cutter bit.
- Precision-fit sealed bearings.
- Easy-adjusting pivot pin.
NOTE: Cutting bit wears only in the dimension of the thickness of material cut. Adjusting bit up or down slightly will expose a new cutting edge and thus increase life of bit.

Can the HC1 Hole Cutter be used to cut 52mm deep composite aluminum sheet with insulated core (as used in cladding and insulated window frame construction)?
Malco’s testing of the HC1 did not cut aluminum material as well as other metals. The bit loads up with the aluminum material and would not be recommended to use the HC1 tool for this purpose.
What size is the hex key for bit on the hole cutter?

Works greatI saved myself a $150 for moving my wood furnace by buying this little jewel. Works great and even though there isn't a manual, it's really easy to figure out with what they send you.
Tip to Reduce Bit BreakageOverall a great tool.Perfect for round holes in sheet metal.I broke 1st bit on second hole in 26 gauge duct.Forty holes later,still using the 2nd bit.Put drill in screwdriver mode & reduce torque setting to lowest value.As soon as bit catches, torque clutch releases & bit stops turning.Release drill trigger,move back a little and start again.
Malco HC1I was adding a couple returns and supplies in the basement during remodeling. This did the trick, definitely wear goggles as this puts out tons of small metal fragments.
One of those tools you’ll only use once in a blue moonUnless you're in a profession that requires it, but when you need to put a round hole in thin sheet metal, there's not much better way to do it than this tool. Also great for metal siding, just make sure your center hole is on a peak in the metal and not a valley.
Love itLove it, made my work much easier. Cutting holes is so much faster with this tool. Saves a lot of time...Would recommend.
