    I think my old age is getting me now. We have a S2 t-160 series cutter and the blade we have been using needs changing. I see where Airmark recommends a 45° blade as standard, a 36° for reflective and a 60° for sandblast medias. I was under the impression a 36° would be the best for universal purposes. Can I receive some feedback on what y'all are using for most cast & calendared vinyl's with good results?

    I don't have a Summa ( we have Roland GR & a GX) Though I usually use a 45° blade. If I'm cutting something thicker than your average vinyl, like reflective vinyl or .020 HIPS then I'll use a 60° blade.

    i run Graphtecs all day long.. 8600-130's and 30' plotters as well and i run a 45 degree blade all day long on cast vinyl, calendared vinyl, vinyl paint mask & printed & laminated contour cut graphics.... I get years out of a Graphtec 45 blade.... If im cutting reflective a lot, ill swap out another dedicated 45 degree blade but i never use a 60 blade... I even cut this small on my plotters...

    This is from Summa, but it's a few years old so maybe they've changed it. We've always used a 36° blade for standard vinyl.

    Another vote for the OEM 45° blade as an all around great choice. I use it for all my 2-6 mil vinyl, laminated or not, kiss or all the way through. This is also on an S2 tangential.

    Thank y'all for your input. 45° it is. I'm also impressed with Von's small cuts on his Graphtec.

    36 or 45 degree for regular vinyl and 60 for reflective

    The 30 for reflective isn't your typical reflective. They're talking about road reflective.... Such as diamond EGP/HI/DG - the ones with a hard shell and prismatic beads. While you can use a 45 with it... It'll likely snap the blade, or dull it really fast. For those you need a k30 blade that's made out of a different stronger steel.

    60 degree is meant for super thin stuff like window tint and really small letters. You don't seem to have an issue cutting small stuff on a 45 degree blade! You should give the 60 a try if you.do that a lot though... It does give it a more.consistant cut, which makes weeding easier (small letters are always a pain).

    And just a note - summa and graphtec do things differently... For the graphtec a 30 is for thick, 45 is for regular, and 60 is for really small thin stuff. On summa it goes 60/45/36.... Complete reversal. So if someone's reading this and confused about the blade degrees.... Just know it's different for different echosystems!
