Why Bigger Isn’t Always Better

For some routing jobs, bigger isn’t always better—sometimes it’s just a hassle. When working on small, precise cuts, using a full-sized router can feel like swatting a fly with an elephant gun. That’s where the trim router comes in.

Originally designed as a laminate trimmer for cabinet and countertop work, the trim router quickly found its place in woodworking shops. This compact tool has proven itself invaluable, offering comfort, control, and versatility that larger routers simply can’t match.

Why Use a Trim Router?

Palm a trim router, and you’ll immediately notice its key advantage—one-handed operation that gives you better control and precision. While full-sized routers are more versatile, a trim router excels at specific tasks, making it an essential addition to any shop. And with prices ranging from half to a third of a full-sized router, it’s easy to justify keeping one or more trim routers pre-loaded with frequently used bits.

Where a Trim Router Excels

While a trim router isn’t built for heavy-duty cutting or use in a router table, it shines in many other areas:

A Ready-to-Go Edger

Most trim routers have motors rated at 1 HP or less, but they are powerful enough for common edge-shaping tasks. They handle round-over, cove, and chamfer bits with ease and can accommodate most 1/4″-shank bits that fit through the base opening. Because of their size, trim routers typically operate at higher speeds than full-sized routers, resulting in cleaner cuts with fewer tear-outs.

Their smaller bases also allow them to navigate tighter spaces where larger routers can’t fit, making them ideal for profiling face-frame edges or flush-trimming solid-wood edging.

A Mighty Mini Mortiser

The lightweight motor and small base make a trim router perfect for routing shallow dadoes and grooves on horizontal and vertical surfaces. Many models feature square bases, which provide stability when running along a straightedge.

When fitted with a straight or down-cut spiral bit, a trim router can quickly create small mortises. For single mortises, freehand routing works well, though final cleanup with a chisel may still be needed. For multiple mortises, using a bearing-guided bit or bushing with a simple jig can greatly reduce chiseling time.

The Countertop King

Despite its many woodworking uses, the trim router still excels in its original role—trimming plastic laminate. When a workpiece is too large or awkward to maneuver on a bench, a trim router makes flush-trimming laminate edges or plywood edging much easier and safer.

Many trim routers come in deluxe kits with multiple bases for increased versatility. Some single-base models still include a trim guide—an adjustable bearing-tipped arm that can turn a regular straight bit into a bottom-bearing flush trim bit. This guide can also be adjusted for additional profile options.

Choosing the Right Trim Router

Trim routers range in price from around $90 for basic models to over $200 for feature-packed versions. Consider these key features when choosing one:

Bit Visibility

Unlike laminate work, where bearing-guided bits handle most of the work, woodworking often requires precise control over the bit tip. Models with large viewing windows or clear acrylic bases make it easier to see your cuts.

Bit Height Adjustment

Older trim routers used basic threaded housings for bit height adjustment, which worked for rough settings but lacked precision. If you plan to use your trim router for edge work, a simple base may suffice. However, for delicate tasks like inlays or fine-tuning a brass hinge recess, look for a model with a threaded depth adjustment for fine control.

Speed Control

Most trim routers run at high speeds, which generally results in cleaner cuts. However, dense hardwoods like maple and cherry can burn at excessive speeds. While fixed-speed routers are fine for most applications, a variable-speed model gives you more control, allowing slower speeds for delicate cuts.

Bit Changing

Trim routers use either a single-wrench spindle lock system or a two-wrench collet. The single-wrench system is more convenient (one less wrench to lose), but two-wrench systems offer more leverage for tightening and loosening. Your preference will likely depend on your experience with other routers.

Extra Bases

Some trim routers come as single-base units, while others offer multi-base kits. While these extra bases are more useful for countertop work, they can provide additional versatility in the shop:

  • Tilting Base: Primarily for laminate trimming but can create unique profiles by changing the bit orientation.
  • Offset Base: Uses a belt-driven chuck to allow routing within 3/4″ of a wall or corner—great for scribing workpieces for a perfect fit or trimming laminate in tight spaces.

If your budget is limited, don’t skip a trim router just because you can’t afford the deluxe kit—you’ll likely use the standard base the most.

  • Electronic Feedback Control: Maintains consistent speed under load for smoother cuts.
  • Interchangeable Bases: Many routers now come with plunge, offset, and tilt bases for greater versatility.

Final Thoughts

Trim routers have come a long way from their humble beginnings as laminate trimmers. Their lightweight design, ease of use, and surprising versatility make them a must-have tool for any woodworker. Whether you’re flush-trimming, edge-profiling, or cutting small mortises, a trim router proves that sometimes, smaller really is better.

If you haven’t added one to your shop yet, now might be the perfect time to do so.
