Abstract:

A tool receiver or chuck is provided which may receive a cutting tool, such as a router bit or the like, therewithin and non-rotatably retain the tool relative to a rotary driving device. The tool receiver includes a plurality of blades substantially encased within a conical surface. A biasing member biases the blades toward a narrow end of the conical surface such that the blades are biased in a tool engaging or operative position. The biasing member and conical surface thus bias the blades radially inward toward the cutting tool such that the blades engage the conical surface and the cutting tool. The tool receiver preferably includes a retaining member, which retains the blades within the conical surface and biases the blades radially outwardly toward the conical surface. The tool may be released by overcoming the biasing force of the biasing member by moving or sliding a retaining ring or by activating a lever or the like, such that no accessory wrenches or tools are required to insert or release a cutting tool or bit. Preferably, a width and radial length of the blades are dimensioned and/or the contact surfaces are defined to provide non-rotating engagement of the cutting tool by the blades, since the conical surface substantially limits twisting of the blades as the blades begin to rotate relative to the tool, thereby locking the tool relative to the blades.
