Best choice for most woodworkers
One 2-1/4 HP motor with both a fixed and a plunge base, so you don’t have to choose.
- Fixed only DEWALT DW618
- Plunge only Makita RP2301FC
A fixed base router holds the bit at one depth, so you set it and start every cut from an edge; a plunge base router rides on spring-loaded columns, so you can start with the bit above the wood and lower it into the middle of a board. Fixed bases are simpler, steadier and better in a router table; plunge bases are needed for mortises, stopped grooves, inlays and stepped deep cuts. If you can only buy one router, buy a kit with both bases.
Below I compare the two bases side by side, show the jobs where each one wins, answer the questions people ask most, and point to three routers that fit each choice. For the full range of routers, see my best router for woodworking picks.
⚡ Quick Pick
Best choice for most woodworkers: the DEWALT DW618PK – one 2-1/4 HP motor with both a fixed and a plunge base.
Choose fixed for edge profiles, rabbets, grooves from an edge and router-table work.
Choose plunge for mortises, stopped grooves, inlays, templates and cuts that start mid-panel.
Plunge vs Fixed Base Router: Side by Side
| Feature | Fixed base | Plunge base |
|---|---|---|
| How depth works | Set before the cut, locked for the whole cut | Bit starts above the wood, plunges to a depth stop |
| Where cuts start | At an edge, or by tilting the router in (not recommended) | Anywhere, including mid-panel |
| Depth precision | Very fine micro-adjust rings | Turret stops for repeat passes; fine adjust varies |
| Handling | Lower, more compact, steadier on edges | Taller and heavier; handles high on the base |
| Router table | The usual choice; some adjust from above | Works, but springs fight height changes unless designed for it |
| Best jobs | Edge profiles, rabbets, grooves from an edge, flush trimming | Mortises, stopped grooves, inlays, templates, deep cuts in steps |
| Cost | Lowest | Slightly higher; a two-base kit costs a little more again |
How a Fixed Base Router Works
In a fixed base, the motor clamps into a sleeve and you set the depth by raising or lowering the motor, usually with a threaded ring or a micro-adjust knob, then lock it. The bit sticks out the same amount for the whole cut. Because the motor sits low in the base, a fixed-base router has a low center of gravity and feels steady on an edge. Its depth adjustment is also the most precise: DeWalt’s DW618 ring moves in 1/64″ steps. It’s the base most people bolt under a router table, and some, like Bosch’s MRC23EVSK fixed base, adjust from above the table.
The limit is that the spinning bit is always exposed below the base, so a cut has to start at an edge. Tipping a fixed-base router into the middle of a board to start a cut is how bits catch and routers jump.
How a Plunge Base Router Works
A plunge base carries the motor on two columns with springs that hold it up. You place the router flat on the wood with the bit above the surface, switch on, unlock and push down to a depth stop, rout, then let the springs lift the bit out before you switch off. A turret under the depth rod gives you three to five preset stops, so you can reach a deep cut in equal passes without touching the setting. That makes the plunge base the right tool for anything that starts or stops inside the board: mortises, stopped flutes and grooves, inlays, hinge mortises with a template and keyhole slots.
The trade-off is a taller, heavier tool with its handles higher up, which feels less steady on narrow edges, and a depth setting that is usually coarser than a fixed base’s micro-adjust.
When to Use Each Base
Use a Fixed Base For
- Roundovers, chamfers, coves and ogees on edges with a bearing bit.
- Rabbets for cabinet backs and picture frames.
- Grooves and dadoes that run out at an edge, with an edge guide or straightedge.
- Flush trimming laminate, veneer and edging.
- Router-table work: molding, rail-and-stile joints, raised panels.
Use a Plunge Base For
- Mortises for mortise-and-tenon joints and loose tenons.
- Stopped grooves, flutes and dadoes that don’t run out at an edge.
- Template work where the cut starts inside the template: hinge mortises, inlays, letters, keyholes.
- Deep cuts in several passes using the turret stops.
- Circles and cut-outs in the middle of a panel.
Plunge cuts need bits made to cut at the tip, such as plunge-cutting straight bits, spiral bits and core box bits; profile bits with a bearing on the tip can’t plunge. My guide to types of router bits shows which is which.
💡 Pro Tip: One Motor, Two Bases
With a two-base kit, leave the fixed base under your router table and move the motor into the plunge base for hand-held jobs. You pay for one motor and get both tools. Read how to use a router for plunge cut and feed-direction steps.
Routers for Each Choice
Three routers that cover the options. All three could be ordered on Amazon when I checked them, and the specs come from DeWalt and Makita.
DEWALT DW618PK Fixed and Plunge Base Router Kit
Best of Both: a Two-Base Kit
The answer to plunge vs fixed for most people is both, on one motor. The DW618PK pairs DeWalt’s 12 A, 2-1/4 HP variable-speed motor (8,000 to 24,000 RPM, soft start) with a DW6184 fixed base and a DW6182 plunge base. The fixed base adjusts on a micro-fine ring in 1/64″ steps; the plunge base has a five-position turret stop and through-the-column dust collection. The motor swaps between them with quick-release latches, and you get 1/4″ and 1/2″ collets and a 3-year warranty. It’s the top pick in my best router for woodworking list.
- ✅ Fixed and plunge bases, one motor
- ✅ 1/64″ depth ring and turret stop
- ✅ 3-year warranty
- ❌ Costs more than a fixed-base router alone
Best For: Anyone who wants to do edge work, table work and plunge cuts with one router.
DEWALT DW618 2-1/4 HP Fixed Base Router
Fixed Base Only
If your work is edge profiles, rabbets, grooves from an edge and router-table jobs, the fixed-base DW618 is the same 12 A, 2-1/4 HP motor with variable speed from 8,000 to 24,000 RPM, soft start, the 1/64″ micro-fine depth ring and a tool-free steel cam lock, without the plunge base. DeWalt sells the DW6182 plunge base separately, so you can add it later and end up with the same kit.
- ✅ Same motor as the kit for less
- ✅ Plunge base can be added later
- ❌ No plunge cuts until you buy the base
Best For: Edge work and a router that will live in a table.
Makita RP2301FC 3-1/4 HP Plunge Router
Plunge Base Only, With Power
A dedicated plunge router makes sense when most of your routing is mortises, stopped cuts, templates and deep work. Makita’s RP2301FC has a 15 A, 3-1/4 HP motor (9,000 to 22,000 RPM), a 2-3/4″ plunge on linear ball bearings, a quick-release depth adjustment with micro control and three preset stops, an electric brake, twin LEDs and a tool-less template guide system. It weighs 13.4 lb, with 1/4″ and 1/2″ collets.
- ✅ Smooth 2-3/4″ plunge on ball bearings
- ✅ Electric brake and LEDs
- ❌ Heavy for edge work
- ❌ No fixed base
Best For: Mortising, template routing and deep plunge cuts.
What About Trim Routers?
Compact trim routers come with a fixed trimmer base and often accept a plunge base too: Makita’s RT0701CX7 kit includes both. A small plunge base on a trim router handles hinge mortises and small inlays well, but it limits you to 1/4″ bits and shallow cuts. For deep mortises and big bits, use a full-size plunge router.
🏆 The Verdict
Pick a fixed base if you mostly shape edges and plan a router table; pick a plunge base if your work is mortises, stopped cuts and templates. For most woodworkers, the right answer is a kit with both bases on one motor, like the DEWALT DW618PK, which costs only a little more than a single base.

Conclusion
The difference between a plunge and fixed base router is where the cut can start. A fixed base starts at an edge and is the steadier, more precise choice for profiles and table work; a plunge base drops into the board for mortises, stopped cuts and templates. Buy a two-base kit and you won’t have to choose. Questions about which base suits your project? Ask in the comments.
