Abstract
A rotary shaper tool for use in conjunction with a power tool used to rotate the shaper tool in which a cutter panel is formed about a cylindrical framework. The cutter panel is formed with rows or sets of cutter teeth and an array of vent holes. Chips formed by the engagement of the spinning cutter panel with a wooden workpiece pass to the interior of the shaper tool and are ejected from the vent holes remote from the area of engagement.
Claims20
A rotary shaper tool, for use in concert with a power tool, for removal of measured amounts of material from a workpiece, comprising:
- a skeletal framework, said skeletal framework being formed about a central axis;
- a flat metallic panel, said panel having at least one tooth formed therein and an opening formed below said tooth;
- said panel further having at least one vent hole formed therein, said tooth and said vent hole being of such size as to permit material removed from said workpiece to pass there through;
- said panel being formed about said skeletal framework to define a cylindrical structure;
- said skeletal framework being rotatable by a power tool, such that when said rotary shaper tool is pressed against a workpiece, material in the nature of chips are removed from said workpiece, the chips being moved through said opening to the interior of said rotary tool and thereafter ejected from said rotary tool through said vent hole.
A rotary shaper tool for use in concert with a power tool to rotate said rotary shaper tool for removal of measured amounts of material from a wooden workpiece, comprising:
- a skeletal framework, said skeletal framework being formed with a central axis;
- a metal cutter panel formed about said skeletal framework;
- said cutter panel being formed with rows of cutter teeth;
- an array of vent holes formed in said panel, said vent holes being so positioned that at least a portion of each said vent hole is aligned with several cutter teeth in the direction of rotation of said rotary cutter tool;
- each cutter tooth having an opening there below and being aligned with, or at least partially aligned with, one vent hole such that when said shaper tool is rotated about said central axis by a power tool and pressed against a workpiece, a measured amount of material is removed therefrom in the form of chips, said chips passing through said opening below said tooth and moving to a vent hole to be ejected from said shaper tool remote from the area of removal.
