Straight Flute Router Bit

[Tom Blank]

Does a carbide straight double flute router bit have any advantages over a carbide spiral cut or shear cut bit?

Thanks.

The other way around in my experience. If I was looking for one it could be that the shearing is directional as in up-cut or down-cut. If you use double sided veneer products, there are bits that meet in the middle to "down" shear (towards center) against the veneer on both sides. Look for UP/DOWN or COMPRESSION bits if this interests you. Again, I can only speak to my experience but, straight cutter show the loss of edge a little more definitely than spirals and shears.

The main advantage of straight fluted bits are that they're affordable, so you don't mind using them for things like MDF, plywood, etc.

When you need to remove a lot of material fast, try a SINGLE flute carbide bit.
