Must-Have Router Bits for Beginners: The Short List

Router Bits at a Glance

Four router bits cover 90% of what beginners actually cut. Skip the 20-piece starter set. Buy these four, learn them well, and add profiles only when a specific project demands one.

Part 1: The Four Bits Worth Buying First

Skill level: Beginner. No prerequisites beyond owning a router. Fixed-base, plunge, and trim routers all work.

A router does different things depending on which bit you put in it. The bit does the cutting; the router is just the motor that spins it. Most beginners make the mistake of buying a large set (20 bits, 40 bits) and using three of them. The smarter move is to buy four specific profiles and know them well.

These four show up in nearly every beginner project:

Flush trim bit

A flush trim bit has a small bearing at the tip (or top) that's the same diameter as the cutter itself. Ride that bearing against a template, and the cutter shaves your workpiece to match. Every copy comes out identical.

Template routing (where one carefully-made template produces as many matching parts as you want) becomes straightforward with this bit. Trimming iron-on veneer edge banding flush with a plywood edge takes seconds. Following a straight fence to clean up a sawn edge produces a glue-ready surface.

Get one with at least 1 inch of cutting length and a 1/2" shank. Katz-Moses recommends the double-bearing version, which runs either bearing in either position. It handles difficult grain without tearout and replaces two single-bearing bits with one.

Roundover bit (3/8" radius)

If you're buying only one bit to start, buy this one first. The 3/8" roundover puts a smooth curved profile on a board's edge. One pass on a shelf, a drawer front, or a tabletop edge, and the piece reads as designed rather than just built.

The 1/4" radius is so subtle it reads almost like a broken corner. The 1/2" radius changes the visual weight of a piece significantly. The 3/8" lands in the middle. It works on almost anything without looking out of place.

Straight bit (3/4" diameter)

Straight bits cut flat-bottomed channels into the material. A dado (a channel running across the grain) holds a fixed shelf in a bookcase. A groove (a channel running with the grain) keeps a drawer bottom in place. A shallow mortise, routed with a straight bit and cleaned up with a chisel, fits hardware, handles, and inlays.

The 3/4" diameter is the most useful starting size because it matches nominal plywood thickness, which makes routing dadoes for plywood shelves straightforward. Get one with 1 inch of cutting length. It handles most dadoes and grooves in 3/4" stock. For more on this bit's capabilities, see the straight router bit guide.

Chamfer bit (45°)

A chamfer is a flat 45° bevel. The chamfer width is controlled entirely by routing depth: a shallow pass gives a hair-thin edge break, a deeper pass gives a bold decorative detail. One bit, many results.

Box lids, furniture leg bottoms, contemporary shelving, serving boards. Chamfer details show up everywhere once you start noticing them. You don't need a collection of chamfer bits. The 45° angle covers virtually all chamfer work.

Part 2: What These Bits Cut in Practice

Each bit shows up in a different category of work:

The flush trim bit and the straight bit do structural work: they create the joints and surfaces that hold pieces together. The roundover and chamfer handle appearance. These four cover the functional and decorative routing that fills year one.

What to skip for now: Raised panel sets (for cabinet doors) require a router table and technique that takes real time to develop. Dovetail bits need a dedicated jig to produce good results. Learn routing fundamentals first, then add the jig when you're ready for joinery work. Large 20–50 piece starter sets include profiles (keyhole bits, multi-profile sets, large cove bits) you won't reach for in years. Buy the four. Expand when a project demands something specific.

Part 3: Shank Size, Brands, and What to Spend

Use 1/2" shank whenever your router accepts it

Router bit shanks come in two diameters: 1/4" and 1/2". A 1/2" shank has roughly four times the cross-sectional material of a 1/4" shank. More material means less deflection under load, less vibration, and a cleaner cut surface. Rockler's beginner guide puts it plainly: whenever your router accepts both sizes, use the 1/2" shank.

For any bit with a cutting diameter over 1 inch, the 1/2" shank is a safety requirement. Running a large-diameter bit on a 1/4" shank creates a shank-failure risk under load. ToolGuyd's analysis covers the engineering in detail if you want to understand why.

If you have a trim router (the small, one-hand-grip style), its collet only accepts 1/4" shank bits, which is fine for that tool. For any mid-size router, use 1/2" shank whenever available.

Brands

Start with Freud. The carbide is consistent across the line, the bits are available at Home Depot, Lowe's, Woodcraft, and online, and the quality holds up for the kind of use a beginner puts on bits. The ToolGuyd brand guide and the broader woodworking community consistently point to Freud as the best value at the mid-range level.

Whiteside is American-made (Claremont, NC) with noticeably better edge retention and surface quality than Freud. Worth buying once you've confirmed you reach for a specific profile constantly enough to justify the premium.

MLCS works for testing out an unfamiliar profile before committing to better carbide. Not the right choice for bits you'll use regularly.

Avoid no-name bits from Amazon. Cheap carbide burns wood faster than it cuts it, dulls quickly, and at high RPM is a safety concern with no manufacturer accountability.

Buy individually, not as a set

The four bits above from Freud run roughly $60–80 total. A 15-piece starter set in that price range packs in profiles you won't use for years. The Router Forums community is consistent on this: start with specific bits for specific reasons, add only when a project demands something you don't have.

With the flush trim bit, the roundover, the straight bit, and the chamfer bit, you can build shelving with dadoes, produce identical template-routed parts, give any edge a finished profile, and add decorative details to furniture. That's a substantial range for four bits and an afternoon of routing practice.
