The Contractor’s Take
After 31 years, I’ve seen homeowners try to sink hidden hangers with a standard 1-inch bit and a prayer. It doesn’t work. To drive a hanger home through a heavy aluminum gutter into the fascia, you need reach and you need precision. This is the exact setup I carry in my Milwaukee M12 kit every single day.

Why these are “Non-Negotiable”:
- 2-inch Magnetic Nut driver: For guard attachment and downspout assembly the 2-inch nut driver is a must have.
- 6-inch Magnetic Nut Driver: For driving home gutter hanger screws you need the 6-inch length to clear the outer edge of the gutter without the body of your drill scuffing the finish. The magnetic tip is a life-saver when you’re 20 feet up and only have one hand free to steady the hanger.
- #30 Double-Ended Cobalt Bits: Standard 1/8″ bits are for hobbyists. A #30 bit is the professional standard for 1/8″ rivets—it provides just enough “breathing room” for the rivet to seat perfectly without fighting it.
- The “Double-Ended” Value: In this business, you will snap a bit or dull a tip. Having a fresh bit on the other end of the shank means you don’t have to climb down the ladder to grab a replacement mid-job.
Pro Tip: Keep these in a small, dedicated “Bit Box” in your Milwaukee M12 case. When you’re standing on a 28-foot ladder, you want to know exactly where your steel is.
The “No-Leak” Sealant: The Contractor’s Standard
Don’t waste your time with hardware store silicone that peels off in a single season. Shop my Contractor’s Toolbox to grab the exact tripolymer sealant I’ve trusted for over 20 years. This isn’t your average caulk; it’s a professional-grade sealant that actually bonds to wet metal and stays flexible for decades. In the Tennessee humidity, you need a ‘Shield’ that doesn’t quit. Get the right gear the first time, and seal your gutters like a pro.
