If you've ever wondered why one cut looks like a pro's and another looks like a beginner's, the secret is often the router bit. Think of router bits as the paintbrushes of woodworking — the quality, shape, and size all change the final stroke. Using the right bit makes your joinery tighter, your edges cleaner, and your grooves truer, saving you time and frustration. Whether you're trimming laminate, shaping an edge, or cutting a dado, the correct bit delivers predictable results that feel satisfying every time.
Straight bits are the workhorses of the router world. Use them for making grooves, dados, and mortises. They come in many diameters, and are perfect when you need a flat-bottom cut or to hollow out a section of wood. Want to rout a channel to hide cables? A straight bit is your go-to tool.
Flush trim bits have a bearing that rides against a template or edge, trimming material flush to a pattern. They’re ideal for copying templates, trimming laminates, and finishing veneers. Picture them like a groom finishing the edges of a suit — precise and clean.
Roundover bits soften sharp edges and add a finished look without a sander. Available in small radii like 1/16 inch up to bigger curves, they give furniture and shelving a comfortable, touchable edge. Think of them as the icing on a cake — small detail, big effect.
Chamfer bits cut an angled edge and are useful for simple decorative profiles or to remove a sharp corner. They’re great for creating bevels for picture frames, door trims, or to add a modern, crisp edge to a project.
Need ornate profiles or classical mouldings? Roman ogee and cove bits bring traditional decorative shapes into modern workshops. They’re often used for cabinet doors, skirting, and decorative trims that demand character and rhythm.
V-groove bits are perfect for sign-making and engraved lettering. They deliver sharp, tapered cuts that pop in painted or stained finishes. If you’re adding routed lettering or a groove detail to a tabletop, this bit gives a crisp result.
Rabbet bits create stepped edges and are used in joinery for hinges or to set glass into frames. Dado cuts are broader and used for shelving slots. These bits are structural tools for projects where parts must fit together snugly.
Router bits are commonly made from high-speed steel (HSS) or carbide-tipped steel. Carbide tips stay sharp far longer and are the preferred choice for hardwoods, laminates, and frequent use. Coatings such as titanium nitride help reduce friction and heat, but the real game-changer is solid carbide or carbide-tipped edges. For most DIYers and pros in the UK, carbide-tipped bits offer the best balance of performance and longevity.
Shank size matters. A 1/4 inch shank fits most compact and trim routers, giving access into tight spaces and lighter cost. A 1/2 inch shank, however, offers greater rigidity, less vibration, and usually cleaner cuts, particularly with bigger diameters. If you’re serious about routing, a router that accepts 1/2 inch shanks and a collection of 1/2 inch bits is a solid investment. Think of it like using a thicker pencil for bolder strokes — steadier and more durable.
Screwfix is a favourite for tradespeople across the UK, offering a wide range of router bits from entry-level sets to branded, professional options. Their quick-click store collection and nationwide availability make them a convenient choice if you need a replacement bit in a hurry.

Toolstation is another trade-focused retailer with competitive prices. They often stock value-for-money sets and branded options, ideal for both DIYers and professionals. If you’re comparing price and basic performance, Toolstation is a smart place to check first, especially for standard straight, roundover, and chamfer bits.

Machine Mart and Robert Dyas supply tools and accessories to both hobbyists and smaller trade operations. Machine Mart can be a good source for industrial or specialist bits, and Robert Dyas is great for quick-buy essentials and seasonal offers. Both stores strike a balance between convenience and product depth.
Reading bit specs helps you match the tool to the job. Key specs include shank diameter (commonly 1/4 inch or 1/2 inch), cutting diameter, cutting length, and overall length. Also check the number of flutes — more flutes often mean a smoother finish but slower chip removal. Look for “carbide-tipped” on the label if you need long life, and note whether a bearing is included for template work. Treat the spec sheet like a map: it tells you where the bit will perform best.
Treat router bits like investments, not disposables. Clean resin and pitch off after cuts using a carbon cleaner, avoid overheating by using shallow passes, and don’t force slow bits through dense material. Store bits in a rack or foam block to prevent nicking. And when the edges dull, either have them professionally re-tipped or replaced — a sharp bit is safer and more precise than a dull one.
Safety is non-negotiable. Always wear eye protection and hearing protection, secure work with clamps, and use a push block or featherboard when working small pieces. Set the depth in small increments and make multiple passes rather than forcing a deep cut. Remember direction of feed: move against the rotation for better control. Think of the router bit like a hungry animal — if you don’t respect it, things can go wrong quickly.
If you’re just starting, a value set is a great way to cover the basics without breaking the bank. They typically include straight, roundover, chamfer, and flush-trim bits. As you grow, buy individual premium bits for the profiles you use most. Professionals often prefer buying a single high-quality bit over repeatedly replacing cheaper ones. It’s the classic trade-off: breadth now, depth later.
Trend is a British brand known for precision and professional-grade bits. Their range covers everything from basic edge profiles to advanced templates, and they’re a common sight in workshops across the UK. If you want consistent results, Trend is a brand to trust.

Router bits span a wide price range. Cheap multi-bit sets might cost a modest sum and suit casual users, while a single premium 1/2 inch carbide bit from a top brand can cost significantly more but last far longer. For most DIYers, a balanced approach works best: keep a small kit of trusted, quality bits for common tasks and supplement with cheaper specialty bits when needed. Think of it as building a tool wardrobe — a few durable staples plus occasional trendy items.
MDF is abrasive and wears bits faster; choose carbide-tipped cutters and take light passes to avoid burning. Softwood is forgiving, so cheaper bits can perform well, but a sharper edge prevents tear-out. Hardwood demands carbide tips and slower feed rates to maintain edge life. For laminate and veneered boards, use a top-bearing flush trim or an anti-chip scoring bit to reduce splintering. Matching the bit to the material is like choosing the right tire for weather — the better the match, the smoother the ride.
Before buying, make a short wishlist: what profiles do you use most, which shank size does your router accept, and which stores near you stock trusted brands? Read reviews, compare price per bit for sets, and consider buying specialty profiles from a specialist retailer like Axminster if your project demands it. Small investments in quality now save you headaches later, and the right bit can turn a good idea into a beautiful finish.
Choosing the right router bit is a mix of understanding profile shapes, material compatibility, and using reliable suppliers. From general retailers like B&Q, Screwfix, and Toolstation to specialist outlets such as Axminster and Machine Mart, the UK offers plenty of options to suit any budget or skill level. Equip yourself with 1/2 inch shank staples, a few high-quality profile bits, and a plan for maintenance — and watch your projects rise from ordinary to exceptional. Ready to tidy up that edge or add a flourish of moulding? The perfect router bit is closer than you think.
