Buying Guide: What To Consider When Choosing Dremel Bits for Cutting Plastic
- Material compatibility: Plastic types vary (PVC, acrylic, polycarbonate). Choose discs and burrs suited for the specific plastic to minimize heat buildup and cracking.
- Cutting vs. finishing: Use cutting bits for initial pass and sizes, then switches to finishing burrs or engraving bits for smooth edges.
- Heat management: Thin resins and acrylics heat quickly; opt for low-heat discs or carbide burrs with efficient chip removal to prevent warping.
- Shank size and RPM: Most hobby bits use 1/8″ shanks and high RPM ranges. Ensure compatibility with your tool and recommended speeds.
- EZ Lock vs. standard mandrels: EZ Lock systems offer faster changes and less downtime; ideal for repetitive plastic cutting tasks.
- Durability and wear: Carbide burrs and diamond-coated discs generally last longer on hard plastics and composite materials, reducing overall replacement costs.
- Edge quality and finish: For clean edges, consider burrs with polished surfaces or coatings that reduce chipping and burr formation on plastics.
- Application scope: If your work includes engraving or detailing, combine cutting discs with carving kits to achieve both accuracy and aesthetics.
- Safety: Wear eye protection and a dust mask when cutting or engraving plastics to control particulates and potential fumes.
