Please choose one of the Carbide Burr Categories above
Tungsten Carbide:
Carbide is the hardest material next to diamonds and will outlast high speed steel cutters.
Use for shaping, smoothing and material removal on hardened steel, stainless steel, cast iron, nonferrous metals, fired ceramics, plastics, hard woods and other hard materials.
Do not use these for drilling holes or for enlarging holes that are less than twice the diameter of the cutter. The tungsten carbide surface can easily catch the side of a hole and break the bit.
Structured Carbide:
Sharp, fast cutting teeth for greater material removal.
Use on fiberglass, wood, plastic, epoxy, rubber, laminates, particle board, soft metals, ceramic tile.
Helpful Tips:
For more stablility, insert the accessory bit all the way into the tool and then back it out slightly before tightening down the collet nut or keyless chuck.
Use higher speeds for hard woods, slower speeds for metals and very slow speeds for plastics (to avoid melting at contact point).
Use the sides of the cutter for effective cutting. The tip cuts poorly and can break under pressure.
