When should I use a spiral router bit?

Can I use a 6mm shank in a 1/4 inch collet?

In short: No, no, no. You can technically do this, unluckily, but it is highly inadvisable. It is a pity that it just looks like one could do it (1/2'' is not far off compared to 12mm, and 1/4'' is ...

I was thinking of buying a router. I tried a router bit in my power drill. It didn't work

A router spins at around 20,000 RPM. Your drill, at top speed, is closer to 300 RPM. Very different animal.

How can you safely operate a router table without a fence?

Sure. In the picture above, the bit has a bearing on it, which sort of acts as a fence. I have that exact set of Woodpecker's radius jigs and use them exactly as pictured. I don't know what purpose ...

Can I run a router bit over its max RPM?

In short: No. Compared to 16,000 RPM, 20,000 RPM is 25% over the specified maximum. Manufacturers -- even cheapish ones -- always calculate in a bit of tolerance, but 25% over limit is a lot. I ...

Routing boards without burn

An oft overlooked reason for burning is excessive pitch build up on the bits. Use a bit cleaner (I use Simple Green) and nylon or brass brush to clean the bit and it will cut much cleaner.
