What do I use to cut Acrylic?

What type of saw?
Typically you would use an over head panel saw, below table saw, or a table saw. For thinner sheets .177” or thinner you can use a jigsaw, band saw, or scroll saw. For thicker material you can use a band saw or jigsaw but the edges will be very rough. For thicker material table and panel saws are best. Whatever saw you choose there must be minimal vibration and enough power to make the required cuts. 


What type of blade?

A carbide tipped blade with a triple chip design is best. This type of blade will give you the most uniform cuts. For the longevity of the blade you should only use it when cutting acrylics.


What are the common blade diameters and tooth selections used for cutting acrylic sheet?

-         10” diameter, 60 and 80 tooth

-         12” diameter, 60,80, and 100 tooth

-         14” diameter, 60,80, and 100 tooth

Size and teeth per blade depends upon the thickness of the acrylic being cut. Thinner sheets require more teeth then the thicker sheets.
