Dremel-Compatible Rotary Tool Blades for Plastic
 |  |  |
Style A | Style B | Style C |
The segmented edge on these blades is coated with diamond grit for cutting plastic. They’re often used for plunge cuts into the center of your material and small, precise jobs, such as trimming 3D-printed parts.
Style C—Style C have round slots so you can see your workpiece better during cuts. The slots also dissipate heat to prevent dulling.
0.007" Wide Cut—Blades with a .007” cut width are good for slow, smooth cuts.
0.011" Wide Cut—Blades with a .011” cut width are coated with coarser abrasives than blades with a .007" cut width. Use them for fast, rough cutting.
