Buying guide: the best high quality router bits for your router

Shank size

Router bits meet the router at the shank, and the listings here use two sizes: 1/4 inch and 1/2 inch. Most of the sets in this guide, including the KOWOOD, MNA and Bosch sets, use a 1/4 inch shank, which fits the collet that compact and mid-size routers ship with. The 70-piece Yonico set uses a 1/2 inch shank, which suits full-size routers with a 1/2 inch collet. Match the shank to the collet your router accepts; none of these listings include an adapter.

Carbide grade

Several makers name the carbide grade: C2 on the KOWOOD 35-piece set, C3 on the MNA 25-piece set, and C3 micro grain carbide on the Yonico 70-piece set. The Bosch listing calls its carbide micrograin and says precision-ground tips give sharper edges and a smoother finish. The KOWOOD 24-piece set describes a Kowood High Grade Carbide blade. Carbide grade reads as a rough guide to edge life, and the listing’s own words are all we have; no maker here states a hardness figure.

How many bits

Set sizes in this guide run from 10 to 70 pieces. The Bosch 10-piece set covers the popular profiles for all routing job applications, from straight and mortising bits to edge-forming and trimming bits, in a small footprint. The 24, 25 and 35-piece sets from KOWOOD and MNA add profiles a maker uses as projects grow. The 70-piece Yonico set is for a shop that wants one box covering furniture, moldings, cabinetry and frames.

The case matters

Every set here ships with a case: a wooden box for the Yonico and KOWOOD 24-piece sets, an aluminum or aluminium carry case for the KOWOOD 35-piece and MNA sets, and a solid wood base with a clear plastic top for the Bosch set. The Yonico box is labeled and mounts on the wall, which keeps 70 profiles easy to find.

Read the limits

The KOWOOD 24-piece listing is the only one that states speed ratings: 18,000 to 24,000 rpm for bits under 1 inch, and 16,000 to 18,000 rpm for bits from 1 to 2 inches. It also states what the bits will not cut: no ferrous metal and no non-wood materials such as steel, iron or sand. Workpieces it names are woods, MDF, particle board and plywood compact panel.

What listings do not tell you

Safety statements are thin across this guide. The KOWOOD 24-piece and Yonico 70-piece listings describe an anti-kickback design, and the Yonico listing adds sealed bearings and a heat-resistant coating; the rest state nothing to score. No listing here states a warranty term, so warranty scores nothing across the guide. The Yonico listing disagrees with itself on weight, as its review covers in detail.

What these sets will not cut

The KOWOOD 24-piece listing says its bits are for wood materials and warns against cutting ferrous metal and non-wood materials such as steel, iron and sand. None of the five listings rate their bits for plastics, composites beyond MDF and particle board, or metal. Keep bits to the materials the maker names.

Project Match

Pair the set to the work:

• Full-shop joinery and profiling: Yonico 70-piece set, 70 bits on a 1/2 inch shank for furniture, moldings, cabinetry and frames.
• Handheld router trim and joinery: Bosch 10-piece set, the popular profiles from straight and mortising to edge-forming and trimming.
• Beginner multipurpose work: KOWOOD 24-piece set, rated for beginners, with tongue and groove plus the common profiles on a 1/4 inch shank.
• Professional woodworking: MNA 25-piece set, C3 carbide tips rated for MDF, hardwood, softwood and particle board.
• Many profiles on a handheld router: KOWOOD 35-piece set, 35 bits with C2 carbide covering most woodwork needs on a 1/4 inch shank.

How the scores add up

Each set is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A spec the listing does not publish scores nothing. The quick picks and tables below reflect the final scores.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

FAQ: lasers and CNC

What router bit shank size do I need?

Check the collet your router accepts. The KOWOOD, MNA and Bosch sets in this guide use a 1/4 inch shank, while the Yonico 70-piece set uses a 1/2 inch shank. Buy the shank your router’s collet fits; none of these sets include an adapter.

Does a higher carbide grade mean a better bit?

C2 and C3 name the carbide grade the maker states: C2 on the KOWOOD 35-piece set, C3 on the MNA set, C3 micro grain on the Yonico set, and micrograin carbide on the Bosch set. The grade hints at edge life, but the listing’s wear claims are the maker’s words, not measured data.

Can I use these bits on materials other than wood?

The listings name wood, MDF, hardwood, softwood, particle board and plywood compact panel. The KOWOOD 24-piece listing warns against ferrous metal and non-wood materials such as steel, iron and sand. None of the five listings rate their bits for metal or plastic.

How many bits does a beginner need?

The Bosch 10-piece set covers the popular profiles for all routing job applications, and the KOWOOD 24-piece set calls itself multipurpose for beginners. A small set teaches which profiles you reach for; a big set like the 70-piece Yonico box suits a shop doing varied joinery and trim.

What speed should I run a router bit at?

Only the KOWOOD 24-piece listing states speeds: 18,000 to 24,000 rpm for bits under 1 inch, and 16,000 to 18,000 rpm for bits from 1 to 2 inches. The rest of the listings state nothing, so follow your router maker’s guidance for the bit diameter you are using.
