The 2230 kit comes complete with a #30 Jacobs Chuck Handpiece, a heavy-duty plastic foot control with solid state electronics, and a 54 piece assortment of professional jewelers accessories. The kit includes many of the newest items for metal working like Trizact bands, ScotchBrite EXL wheels, Metal Master wheels and rods, CW wheels and Platinum Blue and White compounds. The kit is covered by a two-year manufacturer's warranty on the motor and foot control.
