For people on a tight budget, having the ability of a single router to switch between a fixed base and plunge base configuration may seem to be ideal. Only 30 to 60 seconds are needed to switch this router between the two base options. The cost of this kit, without adjusting for inflation, is less than what I paid for a Milwaukee 2 HP fixed base router roughly 33 years ago (adjusted for inflation, that 2 HP router would have cost $653 today). I much prefer having dedicated routers that are permanently set in a fixed base or plunge base configuration. Some operations, such as cutting dovetails with a jig, may require dedicating a fixed based router or two for just that one task, so as to avoid wasting considerable time fine tuning the router’s depth of cut to create tight fitting dovetail joints. The PantoRouter that I bought a few months ago included a fixed base Bosch 1617 EVS router. That router in the PantoRouter has performed well, although I managed to stall out the motor in that router a couple of times while cutting a ½” wide through-groove in 1 ½” thick hard maple, likely cutting between ¼” and ½” deep in each pass. Other than those stall outs, I am very happy with that router. Shortly after I bought the PantoRouter with the Bosch 1617 EVS router, I bought a used Bosch 1617 EVSSPK kit at a small woodworking business closure auction for $65. That kit was missing the sub-base for the plunge base, the ½” collet, the collet wrenches, and the plastic chip deflectors. The plunge depth stop on the plunge base was bent, the thumbscrew on the plunge depth lock was apparently replaced with a hex head screw, and the previous owner had partially ground away the plastic that helps to prevent the router from being turned on accidentally. Replacing the sub-base for the plunge base, the ½” collet, and the collet wrenches with new parts approximately doubled the cost of this used router kit. During Amazon’s recent sale on the Bosch 1617 EVSSPK kit, I bought a new Bosch 1617 EVSSPK kit, thinking that I could use the router motor from this kit as an emergency spare for the router in the PantoRouter, should that router motor fail in the next few years (the ground away plastic surrounding the power switch on the used router could lead to safety concerns when used in the PantoRouter). Unlike some of the recent reviewers of this kit, I received a new router – the router has a few minor blemishes in the metal portions of the router, but nothing that affects performance. Out of the box, the chip shield for the plunge base had a roughly ½” long crack on one side, as shown in the closeup picture. The depth adjustment for the fixed base worked smoothly, so I put a ½” wide two flute spiral bit into the router, set the depth of cut to 9/16”, and made a test cut in red oak. The router has plenty of power to make that cut. However, as seen at the left of the close up picture, the bottom of the cut was not perfectly smooth – there are visible lines at the bottom of the cut, possibly a few 1/1000 of an inch deep, suggesting that something in the router may have been flexing during the cut. I saw the same visible lines at the bottom of the cut when using the plunge base. The depth of the plunging action is shorter by possibly an inch compared with the plunging action of my 34 year old Bosch 1611 EVS dedicated plunge router and my Bosch 1619 EVS dedicated plunge router. The plunging action of the new Bosch 1617 EVS plunge router base is rough compared to the plunging action of my two dedicated plunge routers, and the plunge base that came with the used Bosch 1617 EVS kit. The plunging action will sometimes not auto-release at the bottom of the cut to pull the router bit up without upward pressure applied to the handles. The rubber boot that covers the right plunge rod will often bow to the right during a plunge (this bowing is visible in the attached pictures). I am not sure if the rougher than expected plunging action is due to insufficient lubricant, a problem with the right side rubber boot, the 22F temperature in the shop (the plunge action in the other routers seemed to work fine at this temperature), or this is expected plunging behavior when the router is new. The handles on the plunge base provide good control of the router in operation and when turning on the router. I have mixed feelings about the round knobs on the fixed base of the kit. The round knobs seem to provide decent control of the router when in use, but when switching the router on with the router not in contact with a board, the round handles do not provide a lot of control. As the router’s motor has a soft start feature, and the position of the on-off switch does not change position at different depths of cut, the opportunity for losing control of the router when switching the router on is likely low. Many of the older Porter Cable fixed base routers in the 2 ¼ HP and lower range also used round knobs for handles, but the position of the on-off switch changes as the depth of cut changes with those routers, so the risk of losing control of those routers when turning them on is a bit higher than with this router kit. For fixed base routers, I prefer the Milwaukee body-grip routers that allow firmly cradling the router body with one hand while the other hand activates the power switch – the current versions of those body-grip routers are manufactured in China, while this router is assembled in Mexico. D-handle routers, with the power switch integrated into one handle, also offer much more control than do the round handles on the fixed base in this router kit. The plunge base in this router kit works with the Bosch RA1054 deluxe router edge guide that I bought earlier this year to use with my 34 year old Bosch 1611 EVS router (I did not test the edge guide with the fixed base). The thumbscrews that came with that edge guide, which work perfectly with my 1611 EVS router, also work in the plunge base for this kit – that is an impressive dedication to product compatibility. I installed the plunge base components from the Bosch RA1173AT dust extraction kit in the plunge base. A Festool dust extractor was able to directly connect to that additional cost component, and likely collected 95%+ of the saw dust when I repeated the 9/16” depth of cut test in red oak with the ½” wide spiral router bit. It would be nice if that dust extraction kit were included with this router kit, but not if including those parts raised the purchase cost by the cost of that kit (roughly $35).
