Malco HC1 2 in. to 12 in. Sheet Metal Hole Cutter Accessory for 1/4 in. or Larger Drill, Multi

Works as described.

This new rendition has solved the problems of their prior product! The cut was absolutely perfect and smooth. It’s really easy to use. Seems a lot more durable than its predecessor. Good value for the workman. Fits all drills pretty much It cut this 8 inch hole perfectly in HVAC flat stock for my kitchen fan.

I needed to drill out a lot of 4" holes in tin on my metal shop for lights, thought a carbide hole saw would work... don't even try it. I used a 1/2 bit as a starter hole and then used my Makita nibbler, it sucked but worked. I then saw this tool used on some social media post by a guy that builds barndos for a living. Bought this and holy crap, I will forever use this for holes in tin. Cuts like butter even on my thicker gauge PBR panels. PERFECT holes, fast and easy. Built well, heavy duty. Genius idea! GET ONE!

It’s a magnificent tool makes everything go really fast extremely easy to use would recommend for any HVAC project cuts like butter, easy Peezy lemon squeezy.

Works well but the item arrives in damaged condition. Manufacture was made aware and suggested returning. The damage is going to happen any way since the frame is not inside the clamshell allowing it to get dinged and banged around. Ours had several chips in the powder coated paint. Using it is super simple but is easiest with a second helper. The drill needs to be high speed and this thing saves a lot of time making those duct work cut outs. Would recommend even if you only plan a few cuts. The cut finish is awesome like a laser cut. Price is a little high for such a simple tool but the end results show why you bought it. Suggestion to manufacture: include a pouch for the tool and allen key along with a spare cutting bit. The price is high enough to do this at no charge.

Great time saver. Sharp bits and perfect circles

Overall a great tool. Perfect for round holes in sheet metal duct. But, I broke the first bit on my second hole in 26 gauge duct. Forty holes later, (6" to 12") I am still using the second bit. The trick was to use a screwdriver/drill combo. I put the drill in the screwdriver mode and reduced the torque setting to its lowest value (1 for my drill). It cuts just as fast as before, but as soon as the bit catches for any reason, rather than breaking, the torque clutch releases and the bit stops turning. Release the drill trigger, move back a little (1/8") and start again. The clutch releases once or twice per hole, but this slight delay is well worth not having to buy bits every few holes. Another thing I started doing was to not finish each hole as this is where the bit seems to hang for me. I leave about 1/4" uncut, then I finish the cut with tin snips.

I used it on round metal duct Worked great Not one issue I would buy again Worth every penny

Terrible, soft alloy! I don’t believe it will last long. Didn’t finish the first cut before drill bit broke! Waste of money! Poor product!

Cut through sheet metal like butter

I am a DIY Handyman, I prefer to tackle most jobs aroung the house myself and try to research the proper tools for the job so I'm prepared. I purchased this and a Rigid right angle drill head for my Ryobi One+ JobPlus multitool, so I could cut 6" circles between the joists of my house into in my existing HVAC trunk lines. I had enough room height wise with 10" joists to fit this tool and a right angle drill. Once I got a hang of it, the tool worked perfectly. I cut 4 holes in a matter of minutes, and didn't break any bits. The instructions state to hand tighten the center pin lock nut, I would recommend using more than you hands to tighten it as I had it come out of adjustment on my first attempt. Angling the tool back slightly helped to get a good cut going.

Easy to use and accurate

So much better than a hole saw for cutting holes in steel soffit for lights. No chatter and damaging adjacent areas. So much faster than a hole saw. I echo the slight angle advice. Slightly varying the depth also helps cut faster
