7 Best Carbide Router Bits in 2021

Disclaimer: All claims are strictly my personal opinion. As an Amazon Associate, I may earn from qualifying purchases.

Carbide router bits have a higher hardness to help for very precise cuts, especially across edges. Users can choose from among three options which include solid carbide, high-speed steel, and carbide tipped.

Those that aim for long-lasting use would go for solid carbide or carbide tipped as it has more strength and endurance than steel.

These tips are not that expensive. In the longer run, they tend to prove beneficial in optimal finishing and economic life. You can use both plastics and hardwood without much trouble.

Buying Guide for Carbide Router Bits

Here we’re going to discuss some of the factors that are important to consider while purchasing router bits, as well as the types of bits you can choose from.

Shank Size

The choice of the shank size is not an option for many router users as it probably supports one size only. But, if the router you’re using is compatible with different collagen sizes, you might want to consider the shank size you want to work with.

The size (diameter) of the shank does affect how the router bit performs and the result. If the shank has a larger diameter, less vibration will occur, and there would be more precision during cutting.

This doesn’t mean that a smaller shank-sized bit would perform worse and give a terrible cut as there are plenty of other factors like the material you’re working on, the length of the bit, etc.

So, if you haven’t yet bought a router and choose to go for the wider bits, make your purchase accordingly. But if you already have a router, look for the shank size compatible with it.

Type of Material

The material you are planning to work on will determine the type of bit you should buy. For softwoods, plywoods, and softwoods, it is best to go for tungsten carbide tips.

These tips are made to last longer than steel bits and lose their sharpness very slowly. This makes it cost-effective for users to purchase them and get that extra bit of finishing due to their sharpness.

If you have to engrave or cut abrasive materials like MDF or particleboard in your project, remember to use solid carbide tips only as they are sturdier than tungsten carbide bits and can work even longer.

Freehand or Table-Mounted Routing?

Both the diameter and the flute type indicate whether you could use the bit on a router table or work freehand with it.

Those router bits with smaller shank sizes like 1/8″ have relatively tiny cutting heads that make it easier for the user to use it freehand. Well, the same goes for ½” shank size bits with small heads; the main focus is on the cutting head.

To sum it up, if the cutting head is small, it’s better to use it freehand. The larger bits that also have a bigger cutting head should be used in a router table only.

Bearing Guided

With this, the need to have a router fence to cut straight or curved edges is eliminated. These bearing-guided tips do it flawlessly on their own and can create some precise edges. The bearing makes it possible to position itself along the lines of the edge for increased accuracy.

These bearing guides are also extremely helpful when you’re using a template on a project. The bit would shape the work while the bearing would carefully follow the template. With these guides, there is no need to go for specialist base plates and guide bushes.


The part of the bit that delivers the cut is called the flute. They might differ in number and, resultantly, affect the actual results and speed and cutting. Working with a single flute bit might not give you a cleaner and smoother finish, but it would certainly speed up the process. With more flutes, you can easily achieve optimal results with smooth finishing.

FAQs about Carbide Router Bits

Here are a few questions that people ask about carbide router bits for money;

What are the Best Carbide Router Bits?

Here is my list of the Best Carbide Router Bits in 2021;

  1. Hiltex Tungsten Carbide Router Bits
  2. Bosch Professional Router Bit Set
  3. HQMaster CNC Router Bits for Wood
  4. StalwartRouter Bit for Woodworking
  5. MLCS 8377 Carbide Router Bit Set
  6. MLCS 8377 Professional Router Bit
  7. Whiteside Spiral Router Bits
  8. FivePears Carbide Router Bits

What is the benefit of using a spiral bit over a straight bit?

You would get a smooth result when using spiral bits, particularly when working on strong end-grain and figured wood material. This is due to the shearing action that is created by the design of the spiral bits.

The cutting edges on a spiral bit are in constant contact with the material you’re working on, unlike straight bits. In essence, a spiral bit would eliminate the need for sanding.

What happens if the bit comes out of the collet and why does it happen?

This did happen with a customer once, as while he was using the straight bit to engrave, the bit came out a little bit which caused uneven grooves in terms of depth.

The reason for this might be the size of the bit shank. If it is too small in diameter, the collet might not be able to hold it properly in place. So, look for brands that are polished to be of the size they claim to be. Otherwise, you can always alter them to make them fit securely.

Another reason why this may happen is due to the router collet being worn out. You should have it checked at your local hardware store and also measure your router bits with a dial caliper for size. This slippage can become a safety hazard and can also ruin your project completely.

Can you use a router bit in a drill press?

You can use these bits in a drill press, but you would have to first make the drill work at a higher rpm in order to get optimal results.
