Plug cutter

A plug cutter adapted for use in a drill press or the like, said cutter comprising

• a holder having one portion adapted to be held for rotation on an axis coincident with the spindle of a drill press, and a second portion defining at least two symmetrically arranged sets of sockets with lands of each set circumaxially spaced and oriented at the same angle to said axis, each set having lands oriented at different angles with respect to said axis,
• cutting blades with portions adapted to be received in said sockets and having projecting portions extending beyond said holder in parallel relationship to said lands to produce a multi-tapered plug, and
• means for securing said blades in said sockets,
• said sockets comprise four in number and being symmetrically arranged circumaxially in said holder to provide at least two pairs of cutting blades, each blade in said pair oriented at the same angle to said axis, and each blade pair oriented at different angles to produce a double tapered plug work piece.

A plug cutter for use in a drill press or the like, said cutter comprising

• a holder having one portion adapted to be held for rotation on an axis coincident with the spindle of a drill press, and a second portion defining at least two sockets with angularly oriented lands inclined with respect to said axis,
• cutting blades with portions adapted to be received in said sockets and having projecting portions extending beyond said holder in parallel relationship to said lands,
• means for securing said blades in said sockets,
• each holder socket more particularly defined by a through slot extending from an outer end of said holder through to an inner end thereof, said socket slot having opposed side lands cooperating with said inclined land to slidably receive said cutting blade, and
• locating means, defined in part by a plug fixed in said holder alongside said socket slot, and in part by the inner end of said blade to locate the blade in the holder.
