Blade to Cut 5" K Style ?

18383 Views 9 Replies 8 Participants Last post by  AAA Gutter
I have a Dewalt 12" miter box.

What's the blade type / set up to cut 5" K style gutter (white alum) to 45 deg and other angles to match the roof pitch ?

Tin snips then rip with your hands. You're going to cover the edge with a miter box or with an end cap anyways, right? If you really want to use your miter saw try a reverse plywood blade. meaning install the plywood blade the opposite way the directions tell you so it actually drags along the metal instead of biting into the metal. You'll get a much cleaner cut that way. I think the saw will slow you down though. I can get a real clean cut with tin snips and even ripping the metal by hand.
I've used a metal chop saw w/ abrasive blade... Clean cut w/ just a little burr to remove..

Snips are just as easy though:thumbsup:
Another vote for backwards ply blade or snips.
A sharp aluminum cutting blade (triple chip grind) works well and leaves almost no burrs. It also works well for cutting downspouts. I also use a DeWalt 12" miter saw, and find that the saw tends to scratch the bottom of the gutter. I put electrical tape on the edges of the saw base to keep this from happening.
My guys would have the whole house run out and cut by the time you set up your miter saw
Thanks a lot fella's.

The guy who installs and provides me lengths was using a miter box on a job a while back with mitered O.C. not box. I just got some lengths the other day but the Hispanic helper couldn't explain too much. The boss said snips.

On the neatness side I was curious about the miter box. I have wiss and med aviators. I guess I need to get some Malco's. I'll keep in mind the abrasive blade. Thanks
snips are how most pro gutter guys i see do it
but there are someguys out there that dont use
miter strips or boxes [not sure how they do it] so i could see
then wanting to get perfect cuts

On copper we miter our corners, not strips or box, and we use snips and get a nice neat perfect cut. I think we can all agree it comes with practice. I'm out of practice myself, but have done it in the past. At this point LOL a saw may be faster for me. I worked a 10 hour day yesterday (Sunday) and I am beat.

We use a Diablo blade on our miter saw to cut aluminum, either downspouts or gutter.

But I do agree that snips are quicker.
