Bosch launched the Colt in 2005 with only a fixed base; to this day it still proves easy to grip and use.…
The new plunge base mirrors Bosch’s mid-size plunger (MRC23EVS, launched in 2011), only smaller. It lacks the power of comparable compact router kits, but it's adequate with a sensible feed rate. This base has the greatest plunge travel and tied for best fine-depth adjustment in our test of six compact routers. But, because the motor fits into the bases only one way and the handles on the plunge base (though comfortable) angle back, it’s not practical to operate the router from its “back” side. (Sometimes we like to angle the power cord toward us.) Neither base comes equipped for using guide bushings—you need to buy an optional attachment (#RA1126, $8) to use Bosch’s proprietary bushings. The kit comes with an edge guide for the fixed base, but you must buy an optional guide (#RA1054, $45) for the plunge base. Also optional: plunge-base dust-collection hoods (#PR012, $15; #RA1175, $18).
