Router table vs. handheld router: which setup for which operation

The router is the most versatile power tool in a furniture shop — with the right bit selection it cuts profiles, joinery, dadoes, mortises, and inlays. But versatility creates a decision point every time you set up a cut: does this operation go better with the router in your hands, or with the work piece running over the router in a table?

This is not a preference question. The geometry of the cut determines which configuration is correct.

The fundamental difference

A handheld router moves through or over the work. You guide the router; the work is stationary. The bit direction relative to the work changes as you change direction.

A router table reverses this: the router is stationary, the work moves over it. The bit stays in one position; you control the feed direction and rate.

This reversal has consequences for each type of operation.

Operations that belong on the router table

Edge profiling on small pieces: the router table is the correct setup for any edge profile cut on a piece that is too small to safely support a handheld router. A handheld router is supported by the work piece surface — if the work is narrow or small, the router base overhangs the edge, the router tips, and the bit digs in unevenly. On the router table, the work rides against the fence and the bit height is fixed; the small piece is fully supported by the table surface.

The practical threshold: any piece smaller than about 6 by 8 inches is safer to profile on the table. This includes most molding work, small box parts, and frame components.

Long edge profiles with a fence: shaping a long profile (a chamfer, roundover, ogee, or cove) along the entire length of a board is more consistent on the router table than with a handheld router. The table fence controls the cut depth consistently across the full length without the variation that occurs when handheld router technique drifts over a 6-foot run.

Raised panel doors: raised panel bits and cope-and-stick sets are designed for router table use. The raised panel bit is large (2.5–3.5 inch diameter), requiring a heavy-duty router (3+ HP) mounted in a table with a fence and a starting pin for safe operation. Running a raised panel bit handheld is possible but substantially more dangerous and produces less consistent results.

Mortising with a fence and stops: a router table with a fence and two adjustable stops (as described in the jig-building article) produces consistent, repeatable mortises across a run of parts. The fence controls mortise width; the stops control mortise length; the bit depth controls mortise depth. The work slides in on one stop, the bit cuts the mortise, the work slides out at the other stop. For a set of 20 chair legs, this is dramatically faster and more consistent than individual handheld router mortising setups.

Rabbets and dadoes across the grain: short cross-grain dadoes (for shelf supports, drawer bottom grooves) are well-suited to the router table with a fence or sled. The table provides consistent depth and the fence controls position accurately.

Operations that belong with the handheld router

Edge profiling on large or assembled pieces: any piece that cannot be run safely through a router table — a full carcass side, a tabletop edge, an assembled cabinet — needs the router to come to the work. A template with a pattern bit (a bit with a bearing that follows the template) guides the handheld router along a curved or profiled edge with consistency.

Template routing: template routing is the technique of cutting a part to a precise shape defined by a template, using a pattern bit or a template guide bushing. This is inherently a handheld (or router table with template support) operation — the template is fastened to the work, and the router follows it. Curved chair legs, shaped table aprons, and complex furniture components are all candidates for template routing.

Inlay and engraving work: routing a shallow pocket for an inlay (brass or wood) or an engraved design is almost always a handheld operation, because the inlay area may be in the center of a large panel, inaccessible to a router table fence.

Routing with a straightedge guide: a clamped straightedge (a piece of MDF or aluminum extrusion clamped to the work) guides a handheld router along a line for dadoes, grooves, and long-grain rabbets. This is faster to set up than a router table for a one-off cut on a large panel and more flexible in positioning.

Flush trimming: trimming an assembly flush — a drawer face flush with a cabinet side, a laminate surface flush with the substrate — requires the router to access the assembled piece in position. A pattern bit or flush-trim bit running in a handheld router along a straightedge or template produces a precisely flush surface.

The half-depth cut rule

For any large-diameter bit (over 1 inch), the first pass should be at half the final bit depth. The final pass brings the cut to full depth and cleans the surface. This applies to both router table and handheld operations. Full-depth cuts with large bits stress the router motor, can deflect the bit slightly (producing a surface that is not the intended depth), and increase the risk of the bit grabbing the work.

In softer woods (pine, poplar, basswood) full-depth single-pass cuts are more forgiving. In dense hardwoods (hard maple, hickory, osage orange), two-pass cuts are the correct default.

Router table investment considerations

A functional router table can be built from a piece of 3/4-inch MDF, a router mounting plate, and an adjustable fence — total material cost under $100. The manufactured router table systems (Bosch, Kreg, Bench Dog, Jessem) add precision, fence quality, and convenience features at prices ranging from $150 to $800 and up.

The two features that separate functional from frustrating in a router table: fence micro-adjustment (the ability to move the fence 1/64 inch without unlocking and repositioning the whole fence) and bit height adjustment (the ability to raise and lower the bit without removing the router from the table). Most mid-range and premium tables have both. Budget tables often have neither.

If you build the router table yourself, add a fence with a micro-adjust mechanism (a carriage bolt and nut system that moves the fence incrementally is sufficient) and choose a router with an above-table adjustment mechanism (Bosch 1617EVS, Triton TRA001) or buy an aftermarket above-table adjustment system.

The router table does not replace the handheld router; the two are complementary. Having both configured and ready — the table set up with the most-used bit, the handheld router on a hook next to the bench with a collet wrench nearby — means the setup time for any given cut is minimized and the correct configuration is always accessible.
