A panel face drilling system using a plunge router wherein an attached guide assembly in conjunction with a guide rail registered to a dual position work holding fixture provides tool guiding means to repeatably drill hole patterns within an array of perpendicular columns and rows. The column and row positions are fixed in relation to the work holding fixture. Nonstandard hole positions are obtainable through use of spacers. The work holding fixture is configured to allow loading of two work pieces at a time each to be aligned against a fence, positioned against a stop, constrained by a resilient clamping means, ready for drilling. By referencing the hole position number sets marked on the tool guiding means one can quickly drill required holes in one panel and then drill a mirror image of that hole pattern in a second panel.
