ABSTRACT:
A material working tool 10 includes a device for working material 18 and a base 12 for supporting the device 18 for working the material. The base 12 includes a rigid member 26 and a cavity 54 defined in the rigid member 26 which is connected to a source of vacuum. A seal 66 is provided about the bottom surface 56 of the rigid member 26. The seal 66 is compressed as a vacuum is created in the cavity 54 so that the rigid member 26 comes into contact with the surface of the working material allowing for the accurate positioning of the material working tool 10 relative to the material to be worked.
