DW-625 Offset Subbase

The 625 offset subbase is 11" long, the router end is ~210 degrees of 6-5/8" diameter circle. The left hand control knob has been removed for easier switch access. Expect the max stability and control whilst routing along the edge of stock. (I make the product; none of the work is farmed out nor made in another country.)

Shown on its side, the plate is drilled on five 1" centers for easy hole and disk making. The pivot pin is supplied. This one accepts PC/DW collar guides. Use it once to make a circle, avoid an accident, drop the tool on the plate (saving the router), do a perfect circumnavigation of the work once, and you may have paid for the device!

I make it an every day practice to study the nature, quality, application and overall friendliness of routers. In my view, the DeWalt 625 is the best 3 HP plunger in the US. Plungers, though most often found upside down in router tables, are designed for hand-held use. They are clumsy when used along the edge of stock but they perform well on inside cuts or cuts where they are surrounded by substrate. That was their design intention, namely, to work well where the fixed base was at risk.

Well, the 625, like the DW 621, is so well made it would be nice to get more than just occasional inside (not along the edge) use out of it. With my new 625 offset subbase you can exploit the plunge function and do most of the heavy outside work of the fixed base router, more than doubling its service.

There is a unique niche in routerdom, the 3+HP fixed base router. There are only 2 examples extant, PC 7518/19 and the Milwaukee 5625. There are at least 13 3 HP plungers and all of which, are handicapped working the edge of stock; they're unstable. With my offset subbase on your DW-625 (or Elu 3337) you'll have more control along the edge of stock or templet, more stability, facility and more utility than the 2 fixed base 3 HP routers. Moreover, you'll still have the inside plunge function.

I've designed the plate like the DW-621, (they are not interchangeable). The circle making function is present. 4, 6, 8, 10, and 12" circles are generated simply by drilling a 3/16" hole in the templet-stock or work piece, inserting a (supplied) 3/16" pin in the hole and the other end in the appropriate pivot hole in the subbase. With a Ľ" cutter in the collet, the operator plunges and rotates the router to make the even numbered holes as indicated.

Besides a larger footprint, the 625 offset subbase large diameter is on the cutter/spindle diameter. There are about 210 degrees of a circle on the router end of the plate, and the cutter is centered to that circle. (Centricity ~ + or - .006-.012"). The same 2 cutter holes, PC/DW counterbored collar/bush and 1-3/4", are available in either the 621 or 625 plates and the prices are the same. For more about the application, ordering, and utility of the 625/621 plates please see the DW-621 Offset page.

A 625 offset subbase with either cutter hole is 46$. A set of both plates is 83$ (W/S&H). PRC straight, solid carbide 1/4" cutter for circle making (depth of cut~3/4"): 24$. The ordering information and pricing schedule at the end of the 621 link apply here.
