A router spins a shaped bit at high speed to cut profiles, grooves, dadoes, and joints in wood. It is the most versatile shaping tool in a woodworking shop — edge profiles, decorative inlays, dovetails, mortises, template work, and sign carving all come from the same tool with different bits and setups. The buying decision starts with whether you need a fixed-base, a plunge, or a combination kit that includes both.
Fixed-Base vs Plunge
A fixed-base router sets the bit depth before you start and maintains it throughout the cut. It is simpler, lighter, and easier to control for edge work and table-mounted routing. For most beginners and general woodworkers, a fixed-base router is the right first choice.
A plunge router lets you lower the spinning bit into the material and then move it laterally. This is essential for interior cuts (mortises, inlays, stopped grooves) where you cannot enter from the edge. Plunge routers are bulkier and slightly harder to control for edge profiling.
Combination kits include one motor and both a fixed base and a plunge base. This is the best value if you need both capabilities. Swap the motor between bases depending on the task. Most major manufacturers offer combination kits in the $200 to $350 range.
Power and Speed
Router power is rated in horsepower or amps. A 1-3/4 HP (11-amp) router handles most woodworking tasks. Larger profile bits and hardwood routing benefit from 2-1/4 HP (15-amp) or more. Compact (trim) routers at 1 HP handle edge profiles and light work but struggle with large bits and deep cuts.
Variable speed is essential. Large-diameter bits must run at lower RPM to keep the tip speed safe and produce clean cuts. A 3-1/2-inch raised panel bit at full speed (25,000 RPM) is dangerous — the rim speed exceeds safe limits and the cut quality is terrible. Variable speed lets you match RPM to bit diameter per the manufacturer's chart.
Soft start gradually ramps up the motor rather than jolting to full speed. This reduces the startup torque that can twist the router in your hands, especially with large bits. It also extends motor and bearing life.
Collet Size
The collet is the chuck that holds the bit shank. Two sizes: 1/4-inch and 1/2-inch. Full-size routers accept both (with a 1/4-inch adapter collet). Trim routers are typically 1/4-inch only.
Half-inch shank bits are stiffer, produce less vibration, and are less prone to deflection during heavy cuts. For any bit larger than about 1 inch in diameter, a 1/2-inch shank is strongly preferred. The extra stiffness produces cleaner cuts and is safer.
If you can only have one collet size, choose a router that accepts 1/2-inch shanks. You can always use a 1/4-inch adapter, but you cannot use 1/2-inch bits in a 1/4-inch-only router.
Essential Router Bits
Roundover bit: the most-used edge profile. Softens sharp edges on shelves, tabletops, and trim. Available in 1/8, 1/4, 3/8, and 1/2-inch radii. A 1/4-inch roundover covers most general use.
Straight bit: cuts grooves, dadoes, and rabbets. Available in 1/4, 3/8, 1/2, and 3/4-inch widths. A 1/2-inch straight bit handles the majority of joinery and groove work.
Flush-trim bit: follows a template to duplicate shapes. The bearing rides along the template while the cutter trims the workpiece flush. Essential for template routing and edge banding.
Chamfer bit: cuts a 45-degree bevel on edges. An alternative to roundover for a more geometric look. Also useful for creating V-grooves when plunged into the surface.
Rabbet bit: cuts a step (rabbet) along an edge for joining panels or setting glass into frames. The depth is set by the bearing size — interchangeable bearings create different rabbet widths from the same bit.
Frequently Asked Questions
Should I get a trim router or a full-size router?
If you only do edge profiling and light work (roundovers, chamfers, hinge mortises), a trim router is lighter and easier to handle one-handed. If you do any joinery, dado cutting, raised panels, or template work, a full-size router is necessary. Many woodworkers own both — the trim router for quick edge work and the full-size for everything else.
Do I need a router table?
A router table turns a handheld router into a small shaper. It is safer and more controlled for small workpieces, narrow stock, and repetitive edge profiling. You can build a simple router table from a piece of MDF and a commercial insert plate for under $100. If you do any volume of routing, a table improves both quality and safety.
