Use 30-50% less downforce, for complete cuts that weed easier for very fine details and thick materials. Clean Cut Roland-style vinyl cutter blades are guaranteed to last longer than OEM or other after-market blades!
Roland Compatible Blades, GS-ROLL-30 - US made carbide brazed to a harden steel blank and are polished to a micro fine cutting edge. This 30° is great for thin material such as window tint, sign gold, or ruby lithe, as well as big lettering.
This blade fits: Roland, GCC, Camm 1, US Cutter, P-Cut, Bridge, Panther, Stika, Allen Datagraph, Zecu, Creation, Rabbit, Lynx
The primary rationale for blades of different angles is cutting depth. A lower angle (45 degree) is great for thin materials, while a steeper angle (60 degrees) has a more vertical cutting orientation that penetrates deeper.
An increased amount of blade dragging through the material when cutting fine detail can cause, what they call, vinyl ears (parts lifted up). With minimal blade in the material, a 60 degree blade tends to cause fewer, if any, vinyl ears.
Using a 60 degree blade on everyday cutting is a waste of a blade, technically speaking. Less of the blade's cutting area is used, and blade life is wasted. The more horizontal cutting orientation of the 45 degree blade accurately distributes the cutting task over a larger blade area, and thus last longer (and is cheaper). So use a 45 degree blade always, unless a 60 degree blade is needed for thick or more custom types of cutting, if 45 degrees blades are not available.
