Router bits are the small metallic attachments at the tip of a router that ensure router's operations through any material. In this article, we will look at the detailed review of CMT Router bits. Usually, bits are varied and are available for a range of purposes. There is no general way of classifying best router bits. They can be grouped according to the material of creation- carbide or high-speed steel(HSS) tipped. Innovation has even led to the manufacture of solid carbide bits which are much more powerful than the normal carbide tipped bits. One can also classify the bits based on their mode of operation- edge bits and non-edge bits.

Edge bits are the ones that can be used for moulding purposes. Non-edge bits, on the other hand, work on the surface of the wood in association with CNC routers to drill holes or carve designs on to it. Router bits can also be classified through their shank diameter. The available standard diameters are ½ inch, 12mm, 10mm; ⅜ inch, 8mm, and ¼ inch, 6mm shanks. No matter what the diameter is, every bit is loaded with a fence.
Edge bits have a ball bearing attached to it that acts as the fence while non-edge bits have a fence attached to the router table or the workpiece! This ensures that you do not scrape off more wood than was required and damage your work in progress! The speed at which the router bits rotate can be maintained in modern machinery. It is better to use the ½" bit because it is sturdier and likely to last longer at such extreme speeds. The speed of a bit can be controlled anywhere between 8,000 to 30,000 rpm.

Why to choose CMT bits?
Why not to choose CMT Bits?
CMT Bits come with the same set of disadvantages as any other router bits. Their durable and precise finish ensures that the bit never comes off the router in working condition. However, if you are not too careful, such a fatal accident can easily take place.
The tips of the bits are made from such things that they are not affected by heightened temperature from repeated use. However, the tips can get so hot that it chars the surface of wood it is working on if you are not too careful.

Freud or CMT? Which router bits are better?
When you are going for router bits both Fred and CMT are very trusted names. However, CMT has incorporated the latest innovations into its products giving way to a more efficient design. Every bit that you purchase from CMT will have a coating of high-density carbide to make it a better and long-lasting cutter. This is not the case with Freud.
On the other hand, Freud is capable of making more durable bits compared to CMT. It is difficult to compare between the two as both of them are equally placed as far as the cutting operations, resharpening, sturdiness, and other such factors are concerned.
To know if your bits have gotten dull, check the router bit by scraping on your finger nail and if it does that that’s a sign of a dull bit. If it burns the wood more often then that can also be an indication of a dull router bit.
Step 1: Clean the bit with a brass brush or a normal brush. This way, all the residue will clean up
Step 2: On the edge or tip of the router. rotate them slowly and check for any shiny spot, it can be a spot or a thin line. if it's there then the bit is definitely worn down.
The best way to sharpen a dull router bit is by using a diamond paddle. Use a 600 grid if the bit is slightly dull and a 30 grid for the ones which are in very bad shape.
In case of a carbide bid, Take out the bearing and start with brushing off the profile edge of the bit. Rub the flat side with the diamond paddle.
Step 1: Clamp the paddle on a workbench
Step 2: Use some water for lubrication and less friction
Step 3: Make 5-10 strokes on the cutting edges, make sure to do so equally on all sides
