USE OUR GREEN ALTERNATIVE - NEVER THROW AWAY ANOTHER DISPOSABLE PLASTIC BLADE HOLDER AGAIN.
There are 6 depth settings to select from. Here are some guidelines for using the holder with the 45° degree Roland blade.
Click setting 1 exposes the least amount of blade and would be used to "kiss-cut" vinyl, including heat transfer vinyl. This means you can cut your vinyl design layer, leaving the backing layer intact. You can then weed your design, apply your transfer tape and set it aside until you're ready to apply the vinyl.
Click setting 2 would be used to cut on thin/light paper, for example sheer vellum, 20 pound printer paper and 40 to 60 pound patterned paper. Other papers like thin cardstock (index cards from Staples) and occasionally a heavier vinyl, like Orajet, will need to be cut at 2.
Click setting 3 will be good for flocked vinyl, flocked heat set vinyl, and cutting completely through smooth vinyl, and textured papers, I recommend using 3 when cutting intricate, small cuts on patterned/design papers.
Click setting 4 is a good mid-range setting. Origami paper, inkjet photo paper, vellum, double-sided patterned paper, brown kraft paper are a few examples. Wausau Astrobrights©, 96 pound premium printer paper, and similar weight papers with intricate cuts also do well with a 4 setting.
Click setting 5 takes on cardstock, medium weight metallic papers, commercial photo paper, adhesive backed cardstock, and thin stencil material.
Click setting 6 handles heavy cardstock, thin acetate, metallic papers, thin chipboard (I highly recommend a 60° Roland blade for all thin chipboard) in a pinch.Stencil material also works but again a 60° Roland blade is a better choice.
These are suggested depth settings only. With so many types of paper, vinyl, and other materials it's impossible to give definitive settings here. So, take the time to play and don't be afraid to sample cut.
Most of all, have fun! Otherwise, what's the point?
