What drill should be used to drill bamboo?
I realise if I ask for very bamboo drill in any tool shop in my town anyone there would make eyes that big. Maybe they would have them in stores like Castorama and Leroy Merlin, but it's kind of trip for me to get there, so I'd rather use something less professional.
What do you suggest?

For more info, Google 'brad point bits'.

Funny, that's the last type of drill I would think about...
I have little experiance with using them but always I use them they leave awulf splinters on the hole's edge. But this is probably my lack of skills, not drill fault.

Good find Ed. Lots of sizes between 3/8 and 1/2!

Might be the quality of the bits. Mejiro has good quality bits as well. Forstner bits (found in most hardware stores) will also work.

Smartass...

With any of these bits, brad point or Forstner, you get what you pay for, like most tools.

Also: bit speed and solid securing of the work (ie, NOT hand-holding it...) have much to do with performance.

I use brad points in a drill press, don't press too quickly and turn the drill off before withdrawing the bit as this sometimes causes the top edge skin to tear.

How holes were put in the flute body before electric tools? I like to use hand drill as it gives me the old-time, pre-modern feeling. But it seems there is no rational explanation of keeping this habit if I want to get things done right.

Karmajampa · 2010-09-18 18:55:55

They used to be burned in using red-hod steel rods. Some people still like to do this today. I would if I could see what I was doing, I think it would be a very interesting way to observe the changes as the hole got larger.

I respectfully disagree. No reason you can't use a hand drill if your heart is in it. Persevere until you get it right!

if u want to make hole by hand totally, u can use hobby knife set, i dont like it, i usually use surgery knife, kind of "Knife Blade Detachable" number 11, i made hundred of flute by using it, but it's a very slow procedure.

I prefer Forstner bits to Brad bits. Past the cutting tip the shaft is narrow so there is nothing touching the bamboo when I turn off the drill press before withdrawing the bit. I won't use Brad bits any more now that I have some Fostners.

+1 on the Forstner bits. I've used pretty much every kind of drill bit there is, Dremel tool, red hot metal....etc... and the best one by far is the forstner bit in a drill press.

Meijiro's bits are frickin' expensive, but they are great:

Go to "Opening finger holes"

Taldaran · 2010-11-03 11:13:34

Forstner for me as well.

Rockler woodworking asked me if I was going to use it very little (cheaper one) or frequently when I was making my choice.

Don't go cheap.

There is really no need to mail order or even go to a specialty shop for forstner bits (in the US at least). They have rather high quality ones at Lowes, Home Depot, and almost any other hardware store, and you may save a dollar or two. They also have them at places like Northern Tool, but they generally carry lower quality stuff.
