Things to Consider while Buying Router Bits for Planing

Not knowing what to look into while buying something is the easiest way to end up with a wrong purchase. So, before you swipe that card of yours on your next bit, make sure that you’ve checked out the following things in it.

Material

For obvious reasons, you can never think of getting a bit made out of poor-quality material. It has to be tough enough to sustain the humongous RPM of your router and keep with all kinds of surfaces you want to work on.

Besides, material quality is the prime determinant of durability. So, picking the right material is what will determine whether it’s going to keep up with you for a long time or will turn into another broken junk.

Shank Size

It depends on what you are going to do. You have to get a suitable size of shank for your router to obtain the best performance. The large diameter of the shank gets you less vibrant while using the router.

That doesn’t mean you’ll always have to take the larger diameter of shanks. If you have the option for choosing the shanks size, then the large diameter is preferable.

Cutting Head

The Cutting Head is usually made of steel(HSS) or with a carbide tip. Carbide tipped is way tenacious than steel and holds the sharpness longer. But you have to be careful using this carbide-tipped head since it gets broken.

Check the quality of the bit before buying. The edges of the head will be precisely furnished, and the braze that meets the carbide tip into the bit will seem even.

Compatible Surfaces

There is a huge impact on which materials or surfaces you are going to cut. If you are going to cut plywood, softwood, or hardwood, then the tungsten carbide tips cutter head is best to fit. These tips contain sharpness much longer than the solid steel bits.

On the other hand, when you are going to cut on MDF or board, the solid carbide bit is way better than the tungsten carbide bit.

Mounted Routing or Freehand Routing

If you are going to use a large diameter for cutting, then you have to mount the router on the table. Such as a 1/2-inch shank router bit. Otherwise, you can carry the router in your hand during the cutting. 1/4-inch shank router bit and 8mm shank router bit can be used as freehand routing.

Flute

The flute is responsible for the cut. It affects the speed as well as the cut by increasing or decreasing the number. If you are using single-bit, then the router performs super-fast but leaves flaws in the tasks. On the other hand, the higher number of flutes slow down your router speed but cut the edges like butter smooth.
