Drill bits for rectangular hole ?

[Alain M-D]

I found this picture on the www.Brisa.fi web site:
It's Drill bits to make the slot in the handle for hiddent tang...
Anyone know where i can find something similar in Canada or USA ?
What is the name of this bit ?

They're not for rectangular holes, but for making a hole elongated, kind of like a drywall bit or Zip router bit. Not as good as a mill, though.

This will be very hard on the bearings of your drill or drill press, even going into wood. They dont have radial thrust bearings, trust me. Not even with a milling bit. I ruined a drill press, good thing it was cheap. (like, actually my friends, on indefinite loan!) Levi

They do make square hole bits for woodworking.It contains a drill bit [round]inside a square sleeve.The drill cuts a round hole and the sleeve cleans up the corners by shearing the wood.

mete, i know (they exist in other shapes too, such as hexagon or octagon), just try to picture a drill bit (nothing extra) rotating and making a square hole When i was younger a friend of mine told me a story about his schoolmate - that guy (the schoolmate) was thick as a brick and didn't know anything about mechanical engineering (in mechanical engineering school ). Once a teacher gave up on that guy and offered him one final chance - if he got that question correctly he'd pass. The question was "what shape of holes do we make with square drill bit ?" - the answer is obvious but the guy answered "square" (and, as the legend goes, replied with "triangular" to teacher's "Huh ?"), flunked the class, dropped out of school and went on to become one of those TV fortune tellers / astrologists. Now whenever somebody mentions square holes i get this vivid image of that klutz from TV in front of a drill press, using square drill bit and drilling square holes It sounds hilarious even if it wasn't for that story

Actually there are machines and bits that can drill square and polygonal holes. Not talking about a mortising machine either. The bit is a funny shape, 3 sided for a 4 sided hole, 4 sided for a 5 sided hole etc. and the head on the machine is an eccentric so that the bit rotates through an orbit while it drills. I don't know anyone that has one, but if you do a google search there are some websites on the process
