Routing adapter for wide shallow recesses
View Patent ↗A router apparatus for cutting grooves in surfaces at a range of depths includes a housing having a central threaded aperture, a set of saw blades with a diameter less than the aperture. In addition, the apparatus includes at least one handle attached to a side of the housing, an adjustment bushing configured for operational engagement with the central threaded aperture, wherein turning the bushing adjusts the cutting depth of the set of saw blades, and a female coupling opposite the set of cutting blades wherein the female threads are operationally engageable with the male threads of a common right-angle grinder.
1. A routing apparatus for cutting grooves in surfaces at a range of depths, the routing apparatus comprising:
a) a housing having a central threaded aperture on a first side of the housing and a second aperture with a first diameter on the second side of the housing;
b) a set of saw blades with a second diameter, wherein said second diameter is less than said first diameter wherein the set of saw blades can move into and out of the second aperture to determine the cutting depth;
c) at least one handle attached to a side of said housing;
d) a cutting depth adjuster comprising:
an adjustment bushing having central bore, the adjustment bushing is configured for operational engagement within said central threaded aperture;
a coupling mounted within the central bore of the adjustment bushing;
one side of said coupling has female threads which are operationally engageable with male threads of a common right-angle grinder;
the opposite side of said coupling is connected to said set of saw blades;
wherein turning the adjustment bushing adjusts the cutting depth of said set of saw blades.
2. The routing apparatus of claim 1 wherein said set of saw blades is three.
3. The routing apparatus of claim 1 wherein said cutting depth adjuster bushing can be locked in place temporarily with at least one set screw.
