PrePackaged Tool Kits take guesswork out of product selection, offer the best value, and feature smart tool combinations for specific applications. They contain just about everything you need to get to work- motor, speed control, handpiece and accessories. When purchased with an optional motor hanger, you are ready to go straight out of the box! Motor and Speed Control carry a 2 Year Warranty. Components: 1. Series TX Motor: Foredom's most powerful flex shaft machines with 1/3HP. They have permanent magnet DC motors that feature the latest in flex shaft technology. These ball bearing models utilize advanced rare earth magnets (in place of the wound fields in Foredom's universal type Series SR motors) that deliver more torque at the low end and throughout the entire speed range of 500 to 15,000 RPM. No other flex shaft gives you greater control of the cutting tool, drill, or bur under any load. It comes equipped with a motor bale for hanging, and Foredom's standard 39? long key-tip inner shaft and outer sheath for connecting to any of Foredom's interchangeable handpieces. Foredom’s permanent magnet motors require the use of a C.TXR, C.SXR, or C.EMX speed control. Damage will result if the motor is connected to any other speed control. 2. C.SXR Speed Control: The C.SXR looks the same as Foredom's standard foot operated control but it has special electronics that converts AC current from an electrical outlet to DC current, the type required by Series TX motors. This control also has a different style plug that is made to fit the motor’s shielded-type plug. The C.SXR offers the same electronics and smooth control as the C.TXR but in a much heavier, cast iron housing. The added weight eliminates any unexpected movement of the control along the floor. The bottom surface of the speed control is covered with non-skid material. CSA listed.
