“Gold Standard” Sheet Metal Hole Cutters and Cutter Bits


Distinctive gold Bits, Bearings and Pivot Pin signify the longest lasting, fastest cutting, easiest adjusting solution for cutting holes in sheet metal. Malco’s sheet metal hole cutter quickly install into the chuck of any corded or cordless drill as small as 1/4″ (6.35 mm). Lightweight aluminum frames make these accessories extremely portable for a variety of hole cutting applications in sheet metal including 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.

The HC1 and HC2 sheet metal hole cutters 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. One cutter bit fits either model and is easily replaceable. These bits are available in 1 pack (#CB), 6 pack (#CBB), and bulk pack (#CB100).

 

Features

  • 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.

Muy bien muchas gracias, thanks.

Works great
I 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 Breakage
Overall 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 HC1
I 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 moon
Unless 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.

Awesome
If you need to cut a hole in sheet metal, this is the tool. You have a clean, professional hole. Will pay for itself many times over.
